    This cross-sectional study aimed to clarify how cognitive biases and situational factors related to diagnostic errors among physicians. A self-reflection questionnaire survey on physicians’ most memorable diagnostic error cases was conducted at seven conferences: one each in Okayama, Hiroshima, Matsue, Izumo City, and Osaka, and two in Tokyo. Among the 147 recruited participants, 130 completed and returned the questionnaires. We recruited primary care physicians working in various specialty areas and settings (e.g., clinics and hospitals). Results indicated that the emergency department was the most common setting (47.7%), and the highest frequency of errors occurred during night-time work. An average of 3.08 cognitive biases was attributed to each error. The participants reported anchoring bias (60.0%), premature closure (58.5%), availability bias (46.2%), and hassle bias (33.1%), with the first three being most frequent. Further, multivariate logistic regression analysis for cognitive bias showed that emergency room care can easily induce cognitive bias (adjusted odds ratio 3.96, 95% CI 1.16−13.6, p-value = 0.028). Although limited to a certain extent by its sample collection, due to the sensitive nature of information regarding physicians’ diagnostic errors, this study nonetheless shows correlations with environmental factors (emergency room care situations) that induce cognitive biases which, in turn, cause diagnostic errors.

    <sec><title>Objectives</title>This study aimed to assess trends in the prevalence of alcohol use depending on smoking behaviours and that of smoking depending on drinking behaviours among Japanese adolescents.

    </sec><sec><title>Design</title>This was a retrospective study using Japanese school-based nationwide surveys conducted between 1996 and 2017.

    </sec><sec><title>Setting</title>Surveyed schools, both junior and senior high schools, considered representative of the entire Japanese population, were sampled randomly.

    </sec><sec><title>Participants</title>We enrolled 11 584–64 152 students from 179 to 103 schools yearly. They completed a self-reported and anonymous questionnaire on smoking and drinking behaviour.

    </sec><sec><title>Results</title>Since 1996, the prevalence of alcohol use and smoking among adolescents decreased in each survey (p&lt;0.01). The prevalence of alcohol use in the non-smokers group was 29.0% in 1996 and 4.0% in 2017, and in the smokers group, it was 73.3% in 1996 and 57.4% in 2017. The reduction rate (the difference in prevalence between 1996 and 2017 divided by the prevalence in 1996) was 0.86 in the non-smokers group and 0.22 in the smokers group. The prevalence of smoking in the non-drinkers group was 6.7% in 1996 and 0.7% in 2017, while that in the drinkers group was 32.5% in 1996 and 18.9% in 2017. The reduction rate was 0.90 in the non-drinkers group and 0.42 in the drinkers group. Therefore, downward trends differed among the groups. In a subanalysis of senior high school students, we divided students into three groups according to their intention to pursue further education. Between 1996 and 2017, there was a consistent difference in the prevalence of alcohol use and smoking among these groups.

    </sec><sec><title>Conclusions</title>Alcohol use and smoking among Japanese adolescents seem to have reduced. However, certain groups showed poor improvements, and health risk behaviour disparity exists, which may widen further. We need to focus on high-risk groups and implement appropriate measures or interventions accordingly.

    <title>Abstract</title>
    <sec>
    <title>Study Objectives</title>
    Sleep problems and problematic Internet use have important implications for adolescent health; however, there have been no large-scale surveys using comprehensive measures. We examined the association between Internet use duration and sleep problems among Japanese adolescents.


    </sec>
    <sec>
    <title>Methods</title>
    We used data from the Lifestyle Survey of Adolescents collected in 2012, 2014, and 2017. We calculated the change in sleep status (insomnia, sleep duration, bedtime, and sleep quality) and Internet usage (screen time and services such as Internet surfing, social media use, streaming such as YouTube, and online gaming). A binary logistic model was estimated for insomnia. Generalized ordered logit models were employed for the ordinal outcomes (sleep duration, bedtime, sleep quality, and multidimensional sleep health). Sampling weights were constructed based on participation rate on survey years and selection rates from population statistics.


    </sec>
    <sec>
    <title>Results</title>
    We analyzed data from 248 983 adolescents. Sleep status was unchanged; however, many adolescents used more Internet services and for longer durations. The odds ratio of Internet screen time for all sleep problems (insomnia, shorter sleep duration, later bedtime, and worse sleep quality) gradually declined. Longer Internet screen time (&amp;gt;5 hours) was strongly associated with all sleep problems. Internet services were also associated with sleep problems; particularly, social media use and online gaming were linked to later bedtimes.


    </sec>
    <sec>
    <title>Conclusions</title>
    Despite the decreased strength in the association between Internet usage and sleep problems, longer Internet time was strongly associated with sleep problems. Public health interventions should consider Internet use as an intervention target to improve adolescents’ health.

    Purpose This study aimed to assess the success of the Japanese government's "Early to bed, early to rise, and don't forget your breakfast" (EB, ER, and DFB) health promotion program for adolescents, which has been ongoing since 2006. Methods We randomly selected 264 junior and senior high schools and conducted a survey of their habits related to EB, ER, and DFB. We defined EB, ER, and DFB as follows: bedtime before 10 p.m. (junior high school) or 11 p.m. (senior high school) and waking-up before 7 a.m., at which point the student should eat breakfast every day. Multivariate analysis was performed on the students' lifestyles, and school-related factors were set as independent variables. Results Data from 84,988 participants (31,474 from junior and 53,514 from senior high school) were analyzed. The effective response rates were 47.9% for junior high schools and 53.7% for senior high schools (overall rate: 51.4%). The data showed that 70-80% of students complied with ER and DFB, while less than 10% complied with EB. For almost all adolescents, "using the Internet >= 2 h/day" was the most negative factor influencing EB, ER, and DFB, and "family rules for using the Internet" was the most positive factor. Conclusions For Japanese adolescents, it is especially important to promote the achievement of EB, and limits on the amount of time and rules for using the Internet were significantly related factors. Further study is required to clarify these causal relationships for an improved implementation of EB, ER, and DFB.

    <title>Abstract</title>

    <title>Study Objectives</title>
    To determine the prevalence of and risk-factors for difficulty waking up for school among adolescents.


    </sec>
    <sec>
    <title>Methods</title>
    We used a self-administered questionnaire (140 junior high schools [JHSs]; 124 senior high schools [SHSs]) selected randomly in 2012 from throughout Japan.


    </sec>
    <sec>
    <title>Results</title>
    Total response rate: 60.7%. Data from 38 494 JHS and 61 556 SHS students were analyzed. The prevalence of at least one instance of school tardiness/absence due to difficulty waking up over a 30-day period was 10.9 (95% confidence-interval:10.5–11.3)%/2.9(2.7–3.1)% for JHS-boys and 7.7(7.3–8.1)%/2.0(1.8–2.2)% for JHS-girls. The prevalence was 15.5(15.1–15.9)%/5.6(5.3–5.9)% for SHS-boys and 14.4(14.0–14.8)%/5.9(5.6–6.2)% for SHS-girls. We used ordinal regression to identify the risk factors associated with the experience of school tardiness/absence. Factors significantly associated with school tardiness in all four groups (JHS boys/girls, SHS boys/girls) were “no-participation-in-club-activities,” “early-morning-awakening,” “feeling bad throughout a morning,” “drinking,” and “smoking.” Among associated factors, the highest odds ratio was found for monthly smoking-days (none vs. at least one-day or more) for JHS-girls at 5.30(3.57–7.85). Factors significantly associated with school absence in all four groups were “no wishing to go to university,” “no participation in club activities,” “disorders of initiating and maintaining sleep,” “long internet use,” “drinking,” “smoking,” “poor-mental-health” and “feeling bad throughout a morning.” Among associated factors, the highest odds ratio was found for monthly smoking-days (none vs. at least one-day or more) for JHS-girls at 4.60(3.45–6.15).


    </sec>
    <sec>
    <title>Conclusions</title>
    These results suggest that the risk factors for difficulty waking up among adolescents are sleep status, lifestyle, and mental health, which can indicate the presence of an underlying disease.

    Telomere length (TL) influences the development of lifestyle-related diseases, and neonatal TL may influence their prevalence. Various factors have been reported to affect neonatal TL. Although the fetus is exposed to multiple conditions in utero, the main factors affecting the shortening of neonatal TL are still not known. In this study, we sought to identify factors that influence fetal TL. A total of 578 mother-newborn pairs were included for TL analysis. TL was measured in genomic DNA extracted from cord blood samples using quantitative PCR. The clinical factors examined at enrollment included the following intrauterine environmental factors: maternal age, assisted reproductive technology (ART) used, body mass index (BMI), gestational diabetes mellitus (GDM), maternal stress, smoking, alcohol consumption, preterm delivery, small-for-gestational-age, neonatal sex, and placental weight. Univariate and multivariate regression analyses were used to verify the relationship between neonatal TL and these clinical factors. The median neonatal TL to single-copy gene ratio was 1.0. Pregnancy with ART was among the 11 factors associated with shorter neonatal TL. From multiple regression analysis, we determined that neonatal TL was significantly shorter for pregnancies in the ART group than in the other groups. We conclude that pregnancy with ART is associated with shorter neonatal TL.

    Unhealthy dietary behaviors in adolescence are an important public health problem. Gender differences in dietary behaviors have already appeared during adolescence. However, few studies have assessed a variety of adolescent dietary behaviors in Japan. We aimed to clarify gender differences in unhealthy dietary behaviors among Japanese adolescents. The participants consisted of 84,988 participants from seventh to 12th grades. Unhealthy dietary behaviors were defined according to the National Health and Nutrition Survey. Multivariable logistic regression was used to analyze a nationally representative sample of Japanese adolescents from the 2014 to 2015 Lifestyle Survey. The effective response rate was 51.4%. The prevalence of unhealthy dietary behaviors (skipping breakfast, snacking, eating out, skipping meals, eating alone at dinner, and subjectively poor diet quality) among boys and girls was 14.2% versus 12.4%, 19.6% versus 14.1%, 10.6% versus 7.0%, 7.9% versus 5.6%, 13.3% versus 12.1%, and 12.3% versus 15.8%, respectively. Compared with boys, girls were more negatively associated with skipping breakfast [OR = 0.76 (95% CI 0.73-0.79)], snacking [OR = 0.67 (95% CI 0.65-0.70)], eating out [OR = 0.62 (95% CI 0.59-0.66)], skipping meals [OR = 0.61 (95% CI 0.58-0.65)], and eating alone at dinner [OR = 0.79 (95% CI 0.76-0.83)]. However, girls were more positively associated with subjectively poor diet quality [OR = 1.19 (95% CI 1.14.1.24)]. The findings suggest that gender differences existed in dietary behaviors. Gender differences in dietary behaviors suggest opportunities for tailoring interventions related to dietary education in schools.

    OBJECTIVE: The prognostic implication of isolated systolic hypertension (ISH), defined as SBP at least 140 mmHg and DBP less than 90 mmHg, among young-to-middle-aged adults remains controversial. We examined the association of ISH with cardiovascular disease (CVD) risk in adults aged 30-49 years. METHODS: In a prospective cohort of representative Japanese general populations from the NIPPON DATA80 (1980-2009), we studied 4776 participants (mean age, 39.4 years; 55.4% women) without clinical CVD or antihypertensive medication. Participants were classified as follows: normal blood pressure (BP) (SBP/DBP, <120/<80 mmHg), high-normal BP (120-129/<80 mmHg), elevated BP (130-139/80-89 mmHg), ISH, isolated diastolic hypertension (IDH) (<140/≥90 mmHg), and systolic--diastolic hypertension (SDH) (≥140/≥90 mmHg). RESULTS: ISH was observed in 389 (8.1%) participants. During the 29-year follow-up, 115 participants died of CVD, 28 of coronary heart disease, and 49 of stroke. Cox proportional hazards models adjusted for demographics and CVD risk factors showed that participants with ISH had higher risk of CVD mortality than those with normal BP [hazard ratio (confidence interval), 4.10 (1.87-9.03)]. The magnitude of CVD mortality risk related to ISH was comparable with that related to IDH [3.38 (1.31-8.72)] and not as great as that related to SDH [5.41 (2.63-11.14)]. We found significant associations of ISH with coronary and stroke mortality. The association of ISH with CVD mortality was consistent across men and women and those aged 30-39 and 40-49 years. CONCLUSION: ISH among young-to-middle-aged Japanese adults was independently associated with higher risk of CVD mortality later in life.

    Evidence regarding the effect of psychological factors and evacuation on cardiovascular disease occurrence after large-scale disasters is limited. This prospective study followed up a total of 37,810 Japanese men and women aged 30–89 years from the Fukushima Prefecture with no history of stroke or heart disease at baseline (2012), until 2017. This period included 3000 cardiovascular events recorded through questionnaires and death certificates. The participants’ psychological distress, trauma reaction, and evacuation status were defined, and divided into four groups based on combinations of psychological factors and evacuation status. We calculated the hazard ratios and 95% confidence intervals for only psychological, only evacuation, or both of them compared with neither using Cox proportional hazard models. Psychological factors along with evacuation resulted in approximately 5% to 25% higher magnitude of stroke and heart disease risk than psychological factors only among men. Compared to neither, the multivariable hazard ratios of those with both psychological distress and evacuation were 1.75 for stroke and 1.49 for heart disease, and those of both trauma reaction and evacuation were 2.01 and 1.57, respectively, among men. Evacuation combined with psychological factors increased the risk of stroke and heart disease risks especially in men after the Great East Japan Earthquake.

    BACKGROUND: From among the global public health concerns, smoking remains one of the most crucial challenges. Especially for adolescents, the increase in the use of electronic cigarettes is controversial, as its use may lead to established smoking. In Japan, where a unique tobacco regulation system exists, the heat-not-burn tobacco market has been growing. However, the prevalence and association of combustible cigarettes and new tobacco-related products have not yet been closely investigated among Japanese adolescents. This study aimed to clarify the prevalence of smoking among adolescents, including new types of tobacco-related products, and to compare the characteristics of their users. METHODS: The 2017 Lifestyle Survey of Adolescents is a nationally-representative survey collected in Japan. From the national school directory, 98 junior high schools and 86 high schools were randomly sampled throughout Japan. The students completed an anonymous questionnaire at school. We calculated the prevalence of use for each type of tobacco product. Then, the use of a combination of products and the characteristics of different types of products were examined. RESULTS: In total, 64,152 students from 48 junior high schools and 55 high schools were included the analysis (school response rate = 56%, Mage = 15.7 years, 53.9% boys). The age-adjusted rate of ever (current) use of electronic cigarettes was 2.1% (0.7%) in junior high school and 3.5% (1.0%) in high school; that of combustible cigarettes was 2.6% (0.6%) in junior high school and 5.1% (1.5%) in high school. The rate of heat-not-burn tobacco use was lower relative to other products: 1.1% (0.5%) in junior high school and 2.2% (0.9%) in high school. An examination of the combined use of the three products identified a high number of dual users. Comparisons between different types of users indicated different backgrounds for combustible cigarette users and new product users. CONCLUSIONS: The prevalence of new tobacco-alternative products is growing in popularity among Japanese adolescents. Dual use is common, and many adolescents use new products only. Moreover, e-cigarettes might attract a broader range of groups to smoking. Continuous monitoring and research are needed to investigate their influence as a possible gateway to tobacco smoking.

    OBJECTIVES: Low sleep quality in adolescents is an important public health concern, as it relates to both their current and future physical and mental health. Furthermore, subjective happiness is also often regarded as a major life goal. Although Japan is an economically powerful country, the reported levels of subjective happiness among Japanese adolescents is low. Thus, this study aims to examine the relationship between subjective happiness and sleep problems in Japanese adolescents. METHODS: We conducted a nationally representative cross-sectional study of adolescents enrolled in junior and senior high schools in Japan. We used a questionnaire to determine the prevalence of sleep problems (eg, insomnia, short sleep duration (SSD) and poor sleep quality) and to evaluate the participants' reported levels of subjective happiness. Multivariable logistic regression analyses were used to examine the associations between subjective happiness and sleep problems. Adjusted variables were basic demographic characteristics (eg, gender and school grade), lifestyle behaviors, and mental health status. RESULTS: Data from 64,329 students were analyzed (age range 12-18 years, mean age 15.7 years, 53.9% male). The results indicated that reported levels of subjective happiness were strongly associated with the prevalence of sleep problems. Linear relationships can be observed between sleep problems and subjective happiness scores. The multivariable logistic regression analysis showed that dose-response association of subjective happiness score was observed with all three sleep problems. CONCLUSIONS: Due to these findings, we recommend that policy makers and school officials educate adolescents on the importance of both subjective happiness and good sleep hygiene.

    Subjective happiness is often regarded as a major life goal. Although Japan is an economically powerful country, the level of subjective well-being reported among Japanese adolescents is lower than in other countries. We aimed to investigate the lifestyle factors related to unhappiness in Japanese adolescents. We collected data through the 2017-2018 Lifestyle Survey of Adolescents, a nationally representative cross-sectional study enrolled in randomly selected junior and senior high schools throughout Japan. We assessed the prevalence of subjective unhappiness in junior and senior high school students according to school life factors and daily lifestyle habits. A multivariable logistic regression analysis was used to examine the associations between these factors and unhappiness. A total of 64,329 students were included in the sample (mean age 15.7 years, 53.9% boys). The average prevalence of unhappiness was 10.2%. The logistic regression analyses indicated that unhappiness was strongly associated with being male and with engaging in unhealthy lifestyle behaviors such as not having breakfast, poor sleep quality, and some problematic Internet usage. Although the prevalence of unhappiness was significantly higher among current smokers and alcohol drinkers, these behaviors were not associated with unhappiness in the multivariable logistic regression analysis. Unhappiness among Japanese adolescents appears to be strongly related to how they spend their daily life. We therefore consider it desirable for school officials to educate students on the importance of happiness and lifestyle factors conducive to happiness.

    BACKGROUND: Diagnostic errors are prevalent and associated with increased economic burden; however, little is known about their characteristics at the national level in Japan. This study aimed to investigate clinical outcomes and indemnity payment in cases of diagnostic errors using Japan's largest database of national claims. METHODS: We analyzed characteristics of diagnostic error cases closed between 1961 and 2017, accessed through the national Japanese malpractice claims database. We compared diagnostic error-related claims (DERC) with non-diagnostic error-related claims (non-DERC) in terms of indemnity, clinical outcomes, and factors underlying physicians' diagnostic errors. RESULTS: All 1,802 malpractice claims were included in the analysis. The median patient age was 33 years (interquartile range = 10-54), and 54.2% were men. Deaths were the most common outcome of claims (939/1747; 53.8%). In total, 709 (39.3%, 95% CI: 37.0%-41.6%) DERC cases were observed. The adjusted total billing amount, acceptance rate, adjusted median claims payments, and proportion of deaths were significantly higher in DERC than non-DERC cases. Departments of internal medicine and surgery were 1.42 and 1.55 times more likely, respectively, to have DERC cases than others. Claims involving the emergency room (adjusted odds ratio [OR] = 5.88) and outpatient office (adjusted OR = 2.87) were more likely to be DERC than other cases. The initial diagnoses most likely to lead to diagnostic error were upper respiratory tract infection, non-bleeding digestive tract disease, and "no abnormality." CONCLUSIONS: Cases of diagnostic errors produced severe patient outcomes and were associated with high indemnity. These cases were frequently noted in general exam and emergency rooms as well as internal medicine and surgery departments and were initially considered to be common, mild diseases.

    BACKGROUND: School teachers have a possibility toward at-risk Internet addiction (IA) due to increased opportunities to use the Internet, along with the spread of the Internet in recent years. Burnout syndrome (BOS) is found to be one of the symptoms related to unhealthy mental health, especially among teachers. This study aims to research the relationship between at-risk IA and the Internet usage or BOS by conducting a nationwide cross-sectional survey and examining the factors associated with IA. METHOD: This study was a cross-sectional survey by anonymous questionnaire. This survey was a random sampling survey of junior high schools across Japan in 2016. The participants were 1696 teachers at 73 schools (response rate in teachers 51.0%). We asked participants for details of their backgrounds, Internet usage, the Internet Addiction Test (IAT) by Young, and the Japanese Burnout Scale (JBS). We divided the participants into either the at-risk IA group (IAT score ≧ 40, n = 96) or the non-IA group (IAT score < 40, n = 1600). To compare the difference between at-risk IA and non-IA, we used nonparametric tests and t test according to variables. To analyze the relationship between the IAT score and the scores of three factors of the JBS (emotional exhaustion, depersonalization, and personal accomplishment), we used both ANOVA and ANCOVA, adjusted by relevant confounding factors. To clarify the contribution of each independent variable to IAT scores, we used multiple logistic regression analysis. RESULTS: In our study, at-risk IA was associated with using the internet many hours privately, being on the Internet both on weekdays and weekends, playing games, and surfing the Internet. In the relationship between IAT score and BOS factor score, a higher score for "depersonalization" had a positive relationship with at-risk IA, and the highest quartile for "decline of personal accomplishment" had a lower odds ratio with at-risk IA by multiple logistic regression analysis. CONCLUSION: We clarified there is a significant relationship between at-risk IA and BOS among junior high school teachers in a nationwide survey. Our results suggest that finding depersonalization at the early stage may lead to the prevention of at-risk IA among teachers. Those who are at-risk of IA may feel personal accomplishment through use of the Internet.

    PurposeDietary behaviors and sleep are important lifestyle factors to protect adolescent health. However, little is known about how dietary behaviors are related to sleep disturbances. The purpose of this study was to conduct a large-scale survey among Japanese adolescents to verify the association between unhealthy dietary behaviors and sleep disturbances.MethodsThis study included 65,688 and 99,581 students enrolled in 140 and 120 randomly selected junior and senior high schools, respectively. A total of 85,931 self-administered questionnaires were collected from 79 junior and 77 senior high schools from 2014 to 2015. The survey included questions on sleep patterns, dietary behaviors, alcohol consumption, and smoking, as well as questions on mental health. For dietary behaviors, we adopted the items on meal habits in the National Health and Nutrition Survey including, the frequency of eating breakfast, the frequency of family meals, and subjective diet quality. We performed a multivariate analysis on the relationship between the dietary behaviors and sleep disturbance.ResultsData from 84,988 questionnaires were analyzed. Boys and girls with less healthy dietary behaviors had a significantly higher prevalence for each sleep disturbance. Subjective sleep quality and insomnia were significantly associated with breakfast frequency, family meal frequency, and diet quality. Short sleep duration was significantly associated with breakfast frequency and family meal frequency, but not with subjective diet quality.ConclusionsOur study suggested that sleep and dietary behaviors affect one another. Those involved in public health education should encourage adolescents to establish healthy sleep patterns as well as healthy dietary behaviors.

    In 2018, a new training program for primary care physicians was launched in Japan. As physicians responsible for the training of new primary care physicians, we have faced many problems, particularly in rural areas. The influence of this new program on primary care physicians in rural areas of Japan has not been sufficiently investigated. The aim of this research was to improve training for primary care physicians in Japan by examining training programs in Sweden, where the population challenges are similar to those seen in Japan. In this paper, we will express our opinions and describe the differences in the primary care fostering systems and clinical research training for generalist in Japan and Sweden.

    Previous large-scale studies suggest that internet gaming disorder (IGD) among children and adolescents has become an important public concern. Minors are known to be particularly susceptible to problematic internet gaming use owing to age-related underdevelopment of cognitive control. It has been shown that precursors of addictions appear during adolescence; therefore, prevention efforts must be established targeting minors who have their first experience with addictive substances and behaviors during pubescence. Since the DSM-5 classification of IGD in 2013, studies on IGD have drastically increased in number. Thus, we performed an updated review of studies of IGD in children and adolescents to assess the clinical implications of IGD. The search included all publication years, using PubMed, MEDLINE, and PsycINFO. Across studies, the presence of IGD had a negative effect on sleep and schoolwork in minors. Additionally, family factors, including the quality of parent-child relationships, were important social factors in minors with IGD. Brain imaging studies indicate that impaired cognitive control in minors with IGD is associated with abnormal function in the prefrontal cortex and striatum. Persistent pathological online game use from childhood may aggravate abnormal brain function; therefore, preventive care and early intervention are increasingly important. Although extant research supports the effectiveness of cognitive behavioral therapy for minors with IGD, effective psychological intervention for minors with IGD is an urgent issue that requires further research. This review, which presents updated findings of IGD in minors, is expected to contribute to the development of future research and be useful in clinical practice in the field of child and adolescent psychiatry.

    BACKGROUND: Hazardous drinking (HD) and heavy episodic drinking (HED) constitute different types of alcohol-related harm. The socioeconomic status (SES) background of various alcohol consumption behaviors is not clear. The purpose of this study was to clarify existing SES differences between HD and HED. METHODS: The 2013 national survey regarding alcohol use among Japanese adults was utilized. The results from 1193 men and 1503 women aged 20-64 years were included in the analysis. Education attainment, household income, marital status, working status, and occupation were adopted as SES determinants. Binomial logistic regression analysis was conducted to estimate the odds ratios (ORs) of HD and HED for each SES group. RESULTS: ORs (95% confidence intervals) of HD were higher among persons with less education among both men [1.61 (1.18-2.20)] and women [1.78 (1.19-2.67)]. The OR of HED in men was significantly higher among those who belonged to high household income, were married, and managers or professionals. The OR of HED among women was higher in persons who were employed, as compared with those who engaged in housework. There were no correlations between HED and educational background. CONCLUSIONS: This study showed that in Japan, a lower educational background for both men and women was associated with a higher risk for HD, while higher current SES for men and working women were associated with a higher risk for HED. It is necessary to recognize the SES differences between HD and HED to achieve a policy to reduce alcohol-related harm.

    OBJECTIVE: This study investigated the association between secondhand-smoke (SHS) exposure and sleep disturbance symptoms. METHODS: This study was a cross-sectional survey of junior and senior high school students throughout Japan. A total of 85,931 adolescents responded, and 84,988 questionnaires were included in the analysis. RESULTS: Adolescents who had never smoked accounted for 88.0% of respondents; among that group 39.1% reported having been exposed to SHS over the previous week. The results of multiple logistic regression analyses indicated that the adjusted odds ratios for insomnia symptoms such as difficulty initiating sleep (DIS), difficulty maintaining sleep (DMS) and early morning awakening (EMA), as well as sleep disturbance symptoms such as subjectively insufficient sleep and short sleep duration (<6 h), tended to be higher both among never-smoking adolescents with SHS exposure and among smoking adolescents, as compared with never-smoking adolescents without SHS exposure. When adolescents with one or more of DIS, DMS, and EMA were defined as having insomnia, the adjusted odds ratio for insomnia was highest for adolescents who smoked, followed in descending order by those exposed to SHS both inside and outside the home, those exposed to SHS only inside the home, those exposed to SHS only outside the home, and never-smoking adolescents without SHS exposure (p < 0.001). CONCLUSIONS: The present study has revealed that SHS exposure is associated with sleep disturbance. Thus, in addition to smoking cessation programs, it is also necessary to endorse measures to protect adolescents from SHS exposure in order to promote good sleep in this population.

    BACKGROUND: The prevalence of Internet addiction (IA) among employed adults has not been reported using a large sample. To clarify the actual status of addictive Internet use among employed adults, this study aimed to evaluate the prevalence and the risk factors of IA and at-risk IA among employed adults in Japan. METHODS: This cross-sectional study surveyed all junior and senior high school personnel in Shimane Prefecture, a rural area in Japan. Eligible participants included 3,211 junior and senior high school personnel (1,259 men and 1,952 women). Participants completed a questionnaire on their activities and factors related to Internet use. RESULTS: The prevalence of IA and at-risk IA was 0.03% and 4.82%, respectively. Furthermore, game playing was shown to be the Internet activity most closely associated with at-risk IA. CONCLUSIONS: This study showed that around 5% of school personnel in a rural area in Japan are at risk for developing addiction to the Internet and that using the Internet for game playing is related to at-risk IA. Our results suggest that employed adults should be instructed to use the Internet properly.

    Previous studies demonstrated independent contributions of plasma free amino acids (PFAAs) and high uric acid (UA) concentrations to increased risks of lifestyle-related diseases (LSRDs), but the important associations between these factors and LSRDs remain unknown. We quantified PFAAs and UA amongst Japanese subjects without LSRDs (no-LSRD, n = 2805), and with diabetes mellitus (DM, n = 415), dyslipidemia (n = 3207), hypertension (n = 2736) and metabolic syndrome (MetS, n = 717). The concentrations of most amino acids differed significantly between the subjects with and without hyperuricemia (HU) and also between the no-LSRD and LSRD groups (p < 0.05 to 0.001). After adjustment, the logistic regression analyses revealed that lysine in DM, alanine, proline and tyrosine in dyslipidemia, histidine, lysine and ornithine in hypertension, and lysine and tyrosine in MetS demonstrated significant positive associations with HU among the patients with LSRDs only (p < 0.05 to 0.005). By contrast, arginine, asparagine and threonine showed significant inverse associations with HU in the no-LSRD group only (p < 0.05 to 0.01). For the first time, we provide evidence for distinct patterns of association between PFAAs and HU in LSRDs, and postulate the possibility of interplay between PFAAs and UA in their pathophysiology.

    Objective: Google+ is one of the most actively used Social Networking Sites in the world. The aim of our study is to characterize the Google+ communities related to diabetes and identify the factors associated with the activity level of these communities. Methods: We conducted a systematic search for diabetes-related Google+ communities. We categorized the principal objective of eligible communities into six themes: (1) awareness creation, (2) providing support and sharing experience, (3) product or service promotion, (4) diet-related topics, (5) exercise-related topics, and (6) others. The themes for the posts were: (1) asking for information, (2) providing information, (3) expressing emotion, and (4) advertisement. Results: We included 145 Google+ communities and 378 posts for analysis. Majority (80.0%) of the communities were focused on "General Diabetics", 11.8% were focused on "Type 1 diabetes", 6.2% were focused on "Type 2 diabetes", and 2.1% were focused on "Gestational diabetes". Majority of the communities (35.2%) had the principal objective "Provide support and share experience". Regarding the user-generated posts, 29.6% posts had at least one "+" ("+" is similar to "like" in Facebook), 17.7% posts had comments, and 89.2% posts had external links. Majority of the posts (69.6%) were focused on "General diabetes", 16.9% were focused on "Type 1 diabetes", 12.4% were focused on "Type 2 diabetes" and 1.15 were focused on "gestational diabetes". The top two themes of the posts were "Providing information" (72.8%) and "Advertisement" (31.5%). Conclusion: Our study revealed that major activity of diabetes-related Google+ communities was related to providing support and information. However, the accuracy and effectiveness of the information in the communities need to be scrutinized further from clinical perspective.

    BACKGROUND: Nicotine concentration in hair is a useful marker of tobacco exposure. Detection of nicotine in the hair of non-smokers indicates passive smoking. Accurate measurement of nicotine among active and passive smokers can help in smoking cessation programs or programs designed to prevent secondhand smoke exposure. OBJECTIVE: To establish, using high-performance liquid chromatography-ultraviolet detection (HPLC/UV), a hair nicotine cut-off value to distinguish active from passive smokers. METHODS: Hair samples were collected from randomly chosen Japanese men (n= 192) between 2009 and 2011. Nicotine and cotinine levels in hair were measured using HPLC/UV with column-switching. T-tests and chi-square tests were performed to compare active and passive smokers, while receiver operating characteristic curves were used to evaluate the effectiveness of the cut-off value. RESULTS: There were 69 active smokers and 123 passive smokers. The nicotine and cotinine concentrations in hair were significantly higher in active than in passive smokers (p< 0.01). The area under the curve for nicotine was 0.92. A hair nicotine cut-off value of 5.68 ng/mg, with a sensitivity of 94.2% and specificity of 87.0%, was identified as the optimal cut-off value for separating active from passive smokers. CONCLUSION: Nicotine and cotinine concentrations in hair clearly distinguished active from passive smokers.

    INTRODUCTION Japan is a developed country with high use of Internet and online platforms for health information. 'Yahoo! Answer Japan' is the most commonly used question-and-answer service in Japan. AIM To explore the information users seek regarding breast cancer from the 'Yahoo! Answer Japan' web portal. METHODS The 'Yahoo! Answer Japan' portal was searched for the key word 'breast cancer' and all questions searched for the period of 1 January to 31 December 2014 were obtained. The selected questions related to human breast cancer and were not advertisements or promotional material. The questions were categorized using a coding schema. High and low access of the questions were defined by the number of view-counts. RESULTS Among the 2392 selected questions, six major categories were identified; (1) suspected breast cancer, (2) breast cancer screening, (3) treatment of breast cancer, (4) life with breast cancer, (5) prevention of breast cancer and (6) others. The highest number of questions were treatment related (28.8%) followed by suspected breast cancer-related questions (23.4%) and screening-related questions (20%). Statistical analysis revealed that the treatment-related questions were more likely to be highly accessed. CONCLUSION Content analysis of Internet question-answer communities is important, as questions posted on these sites would serve as a rich source of direct reflection regarding the health-related information needs of the general population.

    Aims: There are no legal regulations in Japan governing minors' consumption of alcohol-flavoured non-alcoholic beverages (AFNAB); therefore, we examined if their consumption could lead to increased alcohol use among adolescents in Japan. Methods: This cross-sectional study used a nonclinical, nationally representative sample of 38,494 junior (19,662 boys) and 61,556 senior (31,925 boys) high school students recruited in 2012. We measured AFNAB consumption rates and the order that adolescents first consumed AFNAB and alcohol. Results: The AFNAB consumption was strongly associated with alcohol use in high school students. Among all age groups, alcohol was more commonly consumed before AFNAB for both males and females. Conclusions: Consumption of AFNAB is more prevalent among minors than alcohol consumption and it has a strong association with alcohol consumption. However, concerns that AFNAB use would lead to increased alcohol use were not supported because AFNAB consumption usually started after adolescents began consuming alcohol. Short Summary: Consumption of AFNAB is more prevalent among high school students than alcohol consumption and it has a strong association with alcohol consumption. However, concerns that AFNAB use would lead to increased alcohol use were not supported because AFNAB consumption usually started after adolescents began consuming alcohol.

    BACKGROUND: Recently, the association of plasma free amino acid (PFAA) profile and lifestyle-related diseases has been reported. However, few studies have been reported in large Asian populations, about the usefulness of PFAAs for evaluating disease risks. We examined the ability of PFAA profiles to evaluate lifestyle-related diseases in so far the largest Asian population. METHODS: We examined plasma concentrations of 19 amino acids in 8589 Japanese subjects, and determined the association with variables associated with obesity, blood glucose, lipid, and blood pressure. We also evaluated the PFAA indexes that reflect visceral fat obesity and insulin resistance. The contribution of single PFAA level and relevant PFAA indexes was also examined in the risk assessment of lifestyle-related diseases. RESULTS: Of the 19 amino acids, branched-chain amino acids and aromatic amino acids showed association with obesity and lipid variables. The PFAA index related to visceral fat obesity showed relatively higher correlation with variables than that of any PFAA. In the evaluation of lifestyle-related disease risks, the odds ratios of the PFAA index related to visceral fat obesity or insulin resistance with the diseases were higher than most of those of individual amino acid levels even after adjusting for potential confounding factors. The association pattern of the indexes and PFAA with each lifestyle-related disease was distinct. CONCLUSIONS: We confirmed the usefulness of PFAA profiles and indexes as markers for evaluating the risks of lifestyle-related diseases, including diabetes mellitus, metabolic syndrome, dyslipidemia, and hypertension in a large Asian population.

    BACKGROUND: Studies on the association of plasma-free amino acids with gout are very limited and produced conflicting results. Therefore, we sought to explore and characterize the plasma-free amino acid (PFAA) profile in patients with gout and evaluate its association with the latter. METHODS: Data from a total of 819 subjects (including 34 patients with gout) undergoing an annual health examination program in Shimane, Japan were considered for this study. Venous blood samples were collected from the subjects and concentrations of 19 plasma amino acids were determined by high-performance liquid chromatography-electrospray ionization-mass spectrometry. Student's t-test was applied for comparison of variables between patient and control groups. The relationships between the presence or absence of gout and individual amino acids were investigated by logistic regression analysis controlling for the effects of potential demographic confounders. RESULTS: Among 19 amino acids, the levels of 10 amino acids (alanine, glycine, isoleucine, leucine, methionine, phenylalanine, proline, serine, tryptophan, valine) differed significantly (P < .001 to .05) between the patient and control groups. Univariate logistic regression analysis revealed that plasma levels of alanine, isoleucine, leucine, phenylalanine, tryptophan and valine had significant positive associations (P < .005 to .05) whereas glycine and serine had significant inverse association (P < .05) with gout. CONCLUSIONS: The observed significant changes in PFAA profiles may have important implications for improving our understanding of pathophysiology, diagnosis and prevention of gout. The findings of this study need further confirmation in future large-scale studies involving a larger number of patients with gout.

    BACKGROUND: This study aimed to clarify the associations between the frequency and amount of alcohol consumption and problematic Internet use, such as Internet addiction and excessive Internet use. METHODS: A self-administered questionnaire survey was administered to students enrolled in randomly selected junior and senior high schools throughout Japan, and responses from 100,050 students (51,587 males and 48,463 females) were obtained. Multiple logistic regression analyses were performed in order to examine the associations between alcohol use and problematic Internet, use such as Internet addiction (Young Diagnostic Questionnaire for Internet Addiction ≥5) and excessive Internet use (≥5 h/day). RESULTS: The results of multiple logistic regression analyses indicated that the adjusted odds ratios for Internet addiction (YDQ ≥5) and excessive Internet use (≥5 h/day) became higher as the number of days in which alcohol had been consumed during the previous 30 days increased. In addition, the adjusted odds ratio for excessive Internet use (≥5 h/day) indicated a dose-dependent association with the amount of alcohol consumed per session. CONCLUSIONS: This study revealed that adolescents showing problematic Internet use consumed alcohol more frequently and consumed a greater amount of alcohol than those without problematic Internet use. These findings suggest a close association between drinking and problematic Internet use among Japanese adolescents.

    Introduction: Japan is assumed to have serious health and social problems due to Internet overuse, but little is known about the actual conditions. This study was conducted to investigate the prevalence of problematic Internet use (PIU) and associated Internet use in adolescents in Japan. Methods: A nationwide survey of adolescent Internet use was conducted in 2012 and 2013. The participants were 100,050 students from randomly selected junior and senior high schools nationwide who gave valid responses to a self-reported questionnaire. The questionnaire included questions on Internet use and the Japanese version of the Young's Diagnostic Questionnaire (YDQ) as well as other questions related to lifestyle habits. Internet users were classified by gender according to three categories on the basis of their YDQ scores: adaptive use, maladaptive use, and PIU. Results: The estimated prevalence of PIU was 6.2% in males, 9.8% in females, and 7.9% in total; it closely correlated with female gender, school grades, and number of Internet hours. The following common and gender-specific applications that conferred a risk of PIU were identified: downloading (both genders), online gaming (males), social networking services, blogs, and bulletin boards (females). Conclusions: A cross-sectional survey using YDQ of a large number of high school students yielded a PIU prevalence of 7.9% in Japan. This study showed that problems associated with Internet overuse have already become serious; therefore, planning and implementation of prevention and control measures is urgently required.

    The aim of this study was to clarify the association between smoking and problematic Internet use (PIU), such as Internet addiction (IA) and excessive Internet use (EIU), among Japanese adolescents. A self-administered questionnaire was administered to students enrolled in randomly selected junior and senior high schools throughout Japan. Responses were obtained from 100,050 students (0.94:1 ratio of boys to girls). The prevalence of IA (as indicated by a Young Diagnostic Questionnaire for Internet Addiction score ≥5) in all participants, boys, and girls was 8.1%, 6.4%, and 9.9%, respectively. The prevalence of EIU (≥5 hours/day) in all participants, boys, and girls was 12.6%, 12.3%, and 13.0%, respectively. The results of multiple logistic regression analyses indicated that the adjusted odds ratios (AORs) for IA and EIU were significantly higher among students who smoked (including those who previously smoked) than among those who never smoked (p < 0.01 for all comparisons). In addition, the AORs were the highest for students who smoked ≥21 cigarettes per day. The prevalence and AORs of IA and EIU tended to increase with smoking frequency and number of cigarettes smoked per day, indicating a dose-dependent relationship. Thus, IA and EIU have strong associations with smoking. This study revealed that adolescents who routinely smoked or those who smoked more cigarettes per day had a higher risk of PIU than adolescents who did not. These findings suggest that there is a close association between smoking and PIU among Japanese adolescents.

    AIMS: Nationwide surveys to clarify the characteristics and trends of the drinking behavior of Japanese adults were carried out in 2003, 2008, and 2013. METHODS: These were periodical cross-sectional surveys. Subjects were chosen through a stratified two-stage random sampling method. The surveys included drinking frequency and amount, ICD-10 alcoholism diagnostic standards, questionnaire for the determination of harmful alcohol use ( AUDIT: Alcohol Use Disorders Identification Test). In 2003, the surveys obtained responses from 2547 people (73% response rate); in 2008, 4123 people (55% response rate); and in 2013, 4153 people (59% response rate). RESULTS: The proportion of lifetime experience of alcohol dependence diagnosed by ICD-10 was 1.9% for male and 0.2% for female, and the estimated number of patients was 1.07 million. The declining trends were observed in the percentage of daily drinkers and the amount of alcohol consumed per week for male. The lowering of the age for consuming their first alcoholic drink and their first drunken experience was observed among female. The gender difference of prevalence of problem drinking is getting smaller. The binge drinking and heavy episodic drinking were observed especially younger generation. The only small proportion of patients with alcohol dependence had received specialized medical care, whereas the many of these visited medical institutions and health screening. CONCLUSIONS: The survey observed many hidden alcoholic patients, and showed the possibility that the healthcare facilities and health screening became the place of screening and intervention for alcohol dependence.

    OBJECTIVE: This study aimed to clarify the prevalence of anger and impulsivity and its associated factors through a nationwide survey of junior and senior high school adolescent students in Japan. METHODS: A self-administered questionnaire covering (1) personal data, (2) lifestyle, (3) mental health status, and (4) feelings of anger and impulsivity was distributed to junior and senior high school students in Japan. Among the total of 10,955 junior high schools and 5,115 senior high schools nationwide, 130 and 110 were randomly selected, respectively. Of those, 92 junior and 80 senior high schools participated in the survey. The survey period was from December 2008 to the end of January 2009. A total of 95,680 questionnaires were collected. After excluding invalid responses, the remaining 94,777 responses (response rate: 62.3%) were analyzed. RESULTS: From the questions regarding anger and impulsivity, 8.7% (95% CI, 8.5%-8.9%) and 7.5% (95% CI, 7.3%-7.7%) of the participants were considered to have experienced intense anger and impulsivity, respectively. Logistic regression analysis indicated that the odds ratios for experiencing intense feelings of anger were significantly higher (all P values < .05) among students who smoked, consumed alcohol, skipped breakfast, did not wish to go to university, had short sleep duration, had decreased positive feelings, had increased depressive feelings, or used mobile phones for longer hours. The odds ratios for experiencing intense impulsivity were significantly higher among students who smoked, consumed alcohol, skipped breakfast, did not participate in club activities, had short sleep duration, had decreased positive feelings, had increased depressive feelings, or used mobile phones for longer hours. CONCLUSIONS: The results suggest that healthy lifestyle habits, good sleep habits, and improved mental health are important for preventing intense feelings of anger and impulsivity among adolescents.

    BACKGROUND AND AIM: No nationally representative survey of irritable bowel syndrome (IBS) among adolescents has ever been performed in Japan. In the present study, we aimed to clarify the prevalence of IBS among Japanese adolescents and the factors associated with it. METHODS: The items related to the diagnostic criteria for IBS based on the Rome III Diagnostic Criteria for Functional Gastrointestinal Disorders were included in a cross-sectional nationwide survey of "alcohol consumption and smoking habits among junior and senior high school students." The participating schools were sampled from among all junior and senior high schools in Japan using the cluster-sampling method, and self-administered questionnaires were sent to the selected schools by mail. Among 99 416 questionnaires that were collected, data from 98 411 valid responses were analyzed. RESULTS: The results showed that the prevalence of IBS was 18.6%. Although no sex difference was observed in the overall prevalence of IBS, the prevalence of diarrhea-predominant IBS was higher among boys than among girls, and the prevalence of constipation-predominant IBS was higher among girls than among boys. The prevalence of IBS increased with progression of the school grade, and there were the significant relationships between IBS and sleep-phase delay and insomnia symptoms. IBS was also significantly associated with poor mental health status. CONCLUSION: These results indicate that IBS is common among junior and senior high school students, and associated with lifestyle and mental health.

    OBJECTIVES: The objective was to study the relationship between mental health and lifestyles of adolescents using samples representative of Japanese adolescents nationwide. METHOD: The survey was conducted between December 2004 and January 2005 among students enrolled in randomly selected junior and senior high schools. Self-administered questionnaires addressed lifestyles, sleeping habits, and mental health status. Of 103 650 questionnaires collected, 85 158 were analyzed. RESULTS: Population characteristics associated with poor mental health were being female, being a senior high school student, skipping breakfast, not participating in extracurricular activities, not consulting parents about personal matters, parental smoking, students' smoking or alcohol use, poor subjective sleep assessment, and short or long sleeping duration. CONCLUSION: Smoking and anxiety disorders are associated with an elevation in acculturative stress in adolescents. Prepossessing adolescents are in subclinical depression. Results suggest that lifestyles approaches in preventions that target students can be effective in reaching high-risk populations.

    OBJECTIVES: Nicotine in cigarettes is metabolized primarily by CYP2A6-catalyzed oxidation. The CYP2A6*4 allele, in which CYP2A6 is a homozygous whole-deletion variant, completely lacks enzyme activity. The aim of this study was to examine the effects of CYP2A6*4 genetic polymorphism on smoking behavior and nicotine dependence in a general population of Japanese men. METHODS: The subjects were 124 healthy Japanese men who gave informed consent to give saliva samples. The survey items included general information, smoking behaviors and nicotine dependence. The polymerase chain reaction restriction fragment length polymorphism method was used to analyze the genetic polymorphisms of CYP2A6. The subjects were classified into two groups: Group W (CYP2A6*4 absence: *1A/*1A, *1A/*1B and *1B/*1B) and Group D (CYP2A6*4 presence: *1B/*4A, *4A/*4A, *1A/*4A or *1B/*4D, and *1A/*4D). We analyzed the differences in the survey items between the two groups. RESULTS: There were no significant differences in smoking behaviors between the two groups. However, Group D tended to have less difficulty in refraining from smoking after waking in the morning compared to Group W (p=0.051). CONCLUSIONS: CYP2A6*4 genetic polymorphisms may not strongly affect smoking behavior but may possibly have an effect on nicotine dependence.

    BACKGROUND: The Fukushima Daiichi nuclear power plant accident (FDNPPA) was the world's second largest nuclear power plant accident. At the time that it occurred, internet usage prevalence in Japan was as high as 80%. OBJECTIVES: To compare health knowledge on radiation and preventive behaviour between internet users and non-users among adults employed in industries in Fukushima after the nuclear disaster. METHODS: We conducted a cross-sectional questionnaire study among adults employed in industries in Fukushima 3-5 months after the FDNPPA. Targets were 1394 regular workers who took part in health seminars provided by the Fukushima Occupational Health Promotion Center. After applying the selection criteria, there were 1119 eligible participants. The questionnaire asked for personal characteristics and main sources of information about the FDNPPA, as well as health knowledge on radiation and preventive behaviours following the nuclear accident. We assessed the contribution of each variable using logistic regression analysis. RESULTS: Among the eligible respondents, 637 workers (56.9%) were internet users and 482 (43.1%) were non-users. Internet users had more health knowledge than non-users (average 4.6 radiation-related health conditions in internet users vs 3.6 conditions in non-users) and more preventive behaviours (average 2.6 behaviours in internet users vs 1.9 in non-users). According to logistic regression analyses, internet usage was positively associated with greater health knowledge on radiation (OR 1.13; 95% CI 1.08 to 1.20) and more preventive behaviours (OR 1.14; 95% CI 1.07 to 1.23). CONCLUSIONS: Internet usage was significantly and positively associated with greater health knowledge and more preventive behaviours. The internet is a useful method of distributing information to the general public in emergency situations such as a nuclear disaster.

    At the end of 2013, a Japanese newspaper reported that 4,173 children were unidentified or missing in Japan. The article concluded that child abuse was a matter of national concern. In examining the strengths and weaknesses of Japan's welfare system in regard to child abuse, it would seem that a weakness exists with regard to its ambiguity on the roles of different officers who contact suspected cases. Although three types of officer (health, welfare, and police officers) can take charge, child abuse cases might be missed because the division of labor varies between the different types of officer. However, a strength exists in the periodical pediatric health check system that is in place in each of Japan's 1,742 municipalities. To efficiently implement early intervention for child abuse, it is necessary to rearrange the division of labor among the three types of officers to clarify who should intervene in suspected cases.

    We conducted an epidemiological study to examine the associations between sleep environments and sleep habits in Japanese adolescents. The targets were students attending junior and senior high schools throughout Japan. Sample schools were selected by cluster sampling. Self-reported anonymous questionnaires were then sent to the schools for all students to complete. A total of 99416 adolescents responded, with an overall response rate of 64.0%. A total of 96861 questionnaires were subjected to analysis. Associations between sleep environments (type of bed, lighting during sleep, sharing a bedroom) and sleep duration, bedtimes, wake-up times, sleep quality, or symptoms of insomnia were examined. In total, 65.5% of the adolescents surveyed slept on a bed, and 33.0% slept on a futon laid on the floor or tatami. In total, 66.6% slept with the light off, 31.0% slept with a dim light on, and 2.0% slept with the light on. Of those surveyed, 69.3% had their own bedrooms, 17.1% shared a bedroom with one other person, 8.0% shared a bedroom with three people, and 5.0% shared a bedroom with four people or more. The factors with high odds ratios with regard to insomnia were use of a futon laid on the floor or tatami, sleeping with the light on, and not sharing a bedroom. Sleep environments are associated with insomnia. Type of bed, lighting, and sharing a bedroom should be considered as factors that affect the sleep of adolescents.

    OBJECTIVES: To clarify the risk factors for falls in hospital settings and to propose the use of such factors to identify high-risk persons at admission. DESIGN: Prospective cohort study. SETTING: Fukushima Medical University Hospital, Japan, from August 2008 and September 2009. PARTICIPANTS: 9957 adult consecutive inpatients admitted to our hospital. METHODS: Information was collected at admission from clinical records obtained from a structured questionnaire conducted in face-to-face interviews with subjects by nurses and doctors and fall events were collected from clinical records. RESULTS: The proportion of patients who fell during follow-up was 2.5% and the incidence of falls was 3.28 per 100 person-days. There were significant differences in age, history of falling, cognitive dysfunction, planned surgery, wheelchair use, need for help to move, use of a remote caring system, rehabilitation, use of laxative, hypnotic or psychotropic medications and need for help with activities of daily living (ADL) between patients who did and did not fall. Multivariable adjusted ORs for falls showed that age, history of falls and need for help with ADL were common risk factors in both men and women. Using psychotropic medication also increased the risk of falling in men while cognitive dysfunction and use of hypnotic medication increased the risk of falling in women. Planned surgery was associated with a low risk of falls in women. CONCLUSIONS: To prevent falls in inpatients it is important to identify high-risk persons. Age, history of falling and the need for help with ADL are the most important pieces of information to be obtained at admission. Care plans for patients including fall prevention should be clear and considered.

    OBJECTIVES: From our previous results, manganese (Mn) and iron (Fe) in the blood of Parkinson's disease (PD) patients without depression were higher than those of both the PD patients with depression and controls, the hypothesis that "two types of PD exist-PD without depression and affected by Mn and Fe, and PD with depression and unaffected by Mn or Fe" was induced. To investigate the hypothesis, correlations among blood and urine metals were compared in the subjects. METHODS: Subjects comprised PD patients with depression, PD patients without depression and controls recruited from an outpatient clinic in China. Morning blood and urine samples were used to measure concentrations of metals. RESULTS: In the controls, Mn, Fe and zinc (Zn) levels in blood strongly correlated with each other. The correlation coefficient between Mn and Zn in blood was significant in the PD patients with depression and the controls, but not in the PD patients without depression. Correlations of Fe between blood and urine in the PD patients without depression were significant, but not in the PD patients with depression and the controls. CONCLUSIONS: A common route of simultaneous intake of Mn, Fe and Zn could exist in our subjects, however in PD patients without depression, a large intake of Mn may have been from another route. Some results of the PD patients without depression were different from those of the PD patients with depression and the controls. Thus, two types of PD may exist.

    BACKGROUND: Unhappiness at school is one of the main reasons for truancy among adolescents. In order to assess this problem more thoroughly in the context of Japanese adolescents, the present study examined the associations between feelings of unhappiness at school and lifestyle habits, school life realities, and mental health status. METHOD: This study was designed as a cross-sectional survey. A self-administered questionnaire was provided to students enrolled in randomly selected junior and senior high schools throughout Japan. We calculated the percentages of both junior and senior high school students who felt unhappy at school based on factors related to school life, lifestyle habits, and mental health status. Multiple logistic regression analyses were performed in order to examine the associations between those factors and students' feelings of unhappiness at school. RESULTS: A total of 98,867 valid responses were analysed, 7.9% (Boys: 8.4%, Girls: 7.4%) of which came from students who responded that they felt unhappy at school. For both junior and senior high school students, the percentages of those who felt unhappy at school were significantly higher among those who had not yet decided on their future life course, who did not participate in extracurricular activities, did not eat breakfast every day, went to bed late, had used tobacco or alcohol in the previous 30 days, and had poor mental health compared with others. The results of multiple logistic regression analyses indicated that the adjusted odds ratios for feeling unhappy at school with regard to the above-mentioned factors were significantly high for both junior and senior high school students. CONCLUSIONS: The present results suggest that school employees and administrators must provide health guidance to students, considering that irregular lifestyle habits, lower school engagement, smoking, drinking alcohol, and poor mental health status are all associated with maladaptation to school among adolescents.

    In this study, we attempted to clarify the associations between various sleep disturbance symptoms and the frequency and amount of alcohol use among Japanese adolescents. This study was designed as a cross-sectional sampling survey. A self-administered questionnaire survey was administered to students enrolled in randomly selected junior and senior high schools throughout Japan. A total of 99,416 adolescents responded, and 98,867 questionnaires were subjected to analysis. The prevalence rates of sleep disturbance in the 30 days preceding the day of the survey were as follows: subjectively insufficient sleep (SIS) (boys: 37.6%, girls: 38.7%); short sleep duration (SSD) with less than 6 h of sleep (boys: 28.0%, girls: 33.0%); difficulty initiating sleep (DIS) (boys: 12.5%, girls: 14.1%); difficulty maintaining sleep (DMS) (boys: 10.1%, girls: 10.9%); and early morning awakening (EMA) (boys: 5.1%, girls: 5.0%). Adolescents reporting one or more symptoms of DIS, DMS, and EMA were classified as having insomnia, and its prevalence was 21.5%. The prevalence of each symptom of sleep disturbance increased significantly with the number of days on which alcohol was consumed in the previous 30 days and the amount of alcohol consumed per drinking session (p < 0.01). Multiple logistic regression analyses showed that the adjusted odds ratio (AOR) for each symptom of sleep disturbance, except SIS and EMA, tended to increase with the number of days on which alcohol was consumed and the amount of alcohol consumed per drinking session. The prevalence of sleep disturbance is particularly high among adolescents drinking alcohol. The risk of having each symptom of sleep disturbance, except SIS and EMA, increases with the number of days on which alcohol was consumed and the amount of alcohol consumed per drinking session. These findings reconfirm the need to eliminate underage drinking to ensure good sleep among adolescents.

    After the Great East Japan Earthquake on March 11th, 2011, a journalist visited the disaster area with febrile symptoms and was diagnosed with measles of the D genotype, which is not indigenous to Japan. After continuing activities in disaster areas and Tokyo, 11 measles cases were reported, some of which were identified as genotype D. Meanwhile non-profit activities directed towards volunteers were offered including interviews to screen for subjective symptoms, check body temperature and advise volunteers to refrain from working in shelter areas during the period of sickness. As a consequence, disease transmission was controlled among volunteers. In disaster areas, anyone can be an infection vector. In order to prevent transmission of infectious diseases, a field action plan, which includes body temperature checks and standard precautions should be formulated and put into place. If the action plans are shared among local governments and non-governmental organizations (NGOs), they can become a norm and be expected to control infectious disease transmission.

    OBJECTIVE: The main objective of our study was to clarify the prevalence of disorders of arousal (confusional arousals, sleepwalking, sleep terrors) and sleep-related bruxism (teeth grinding) and their associated factors among Japanese adolescents. METHODS: Our study was designed as a cross-sectional sampling survey. The targets were students attending junior and senior high schools throughout Japan. The questionnaire asked for personal data and information on lifestyle, depressive state, and sleep status including the frequency of experiencing disorders of arousal and sleep-related bruxism. RESULTS: A total of 99,416 adolescents responded. The overall response rate was 63.7%, and 98,411 questionnaires were subjected to analysis. The prevalence of disorders of arousal was 7.1% (95% confidence interval [CI], 6.9-7.3%) among boys and 7.7% (95% CI, 7.5-7.9%) among girls. The prevalence of sleep-related bruxism was 2.3% (95% CI, 2.2-2.4%) among boys and 3.0% (95% CI, 2.8-3.2%) among girls. The factors associated with disorders of arousal were the grade in school, smoking habit, alcohol consumption, naptime (min), breakfast habit, participation in club activities, sleep duration, difficulty initiating sleep, nocturnal awakening, early morning awakening, subjective sleep assessment, snoring, decrease in positive feelings, and depression (all p<.001). The factors associated with sleep-related bruxism were gender, smoking habit, nocturnal awakening, snoring, early morning awakening, decrease in positive feelings, and depressive feelings (all p<.001). CONCLUSIONS: If disorders of arousal or sleep-related bruxism are observed in an adolescent, his or her smoking habit, alcohol consumption, sleep status, and depressive state should be considered.

    In 2012, several kinds of electronic books (e-books) became available in Japan. Since several major book retailers launched e-book businesses, it is expected that e-books will become a popular source of information in the country. However, we are concerned that e-books may also be a source of misinformation. In examining 24 available materials published by anti-vaccinists, "atopy businesses", and "wellness maintenance" authors, each was found to contain inaccuracies or misinformation. Thus far, such information is only available in printed books. If these books are scanned and circulated, or published in e-book format, this misinformation may circulate rapidly as e-book devices are becoming popular, and, consequently, harm people's health. We think that it is important for the government to formulate ethical guidelines for the publishing e-books with due consideration to freedom of expression.

    BACKGROUND: The nuclear power plant accidents in Fukushima resulted in a widespread release of radioactive substances in the Fukushima prefecture. AIM: To clarify what factors led to precautions among general workers who displayed preventive behaviours against radiation following the nuclear disasters in Fukushima. METHODS: Descriptive study of preventive behaviours among general workers 3-5 months following the nuclear disasters. The subjects were 1394 regular workers who took part in radiation seminars conducted by the Fukushima Occupational Health Promotion Center between July and August 2011. Of 1217 responses, 1110 eligible responses were included in this study. This anonymous questionnaire survey was asking for characteristics and questions on preventive behaviours following the nuclear disasters. The authors assessed the contribution of each variable by a logistic regression analysis. RESULTS: Keeping track of environmental radiation levels and washing hands and gargling were significantly more frequent among female subjects, older age and workers residing up to approximately 80 km away from the power plants. Washing hands and gargling were also related with living with children. Wearing a mask when leaving home and buying bottled water were significantly more often observed with female subjects and workers residing up to 80 km. Refraining from going outdoors was positively associated with workers residing up to 80 km and workers living with children. CONCLUSIONS: These results provide information that may help with the targeting of health information after a nuclear disaster. This may contribute to determining an order of priority when distributing information after a nuclear disaster.

    After the Great East Japan Earthquake on 11 March 2011, the environmental radiation dose in Fukushima City increased. On 11 April, 1 mo after the earthquake, the environmental radiation dose rate at various surfaces in the same area differed greatly by surface property. Environmental radiation measurements continue in order to determine the estimated time to 50% reduction in environmental radiation dose rates by surface property in order to make suggestions for decontamination in Fukushima. The measurements were carried out from 11 April to 11 November 2011. Forty-eight (48) measurement points were selected, including four kinds of ground surface properties: grass (13), soil (5), artificial turf (7), and asphalt (23). Environmental radiation dose rate was measured at heights of 100 cm above the ground surface. Time to 50% reduction of environmental radiation dose rates was estimated for each ground surface property. Radiation dose rates on 11 November had decreased significantly compared with those on 11 April for all surface properties. Artificial turf showed the longest time to 50% reduction (544.32 d, standard error: 96.86), and soil showed the shortest (213.20 d, standard error: 35.88). The authors found the environmental radiation dose rate on artificial materials to have a longer 50% reduction time than that on natural materials. These results contribute to determining an order of priority for decontamination after nuclear disasters.

    OBJECTIVES: Ever since the Fukushima Daiichi nuclear power plant (NPP) accident, every day about 3,000 workers have been working to repair the situation. The frequent occurrence of heat disorders has been a concern for the workers wearing protective clothing with poor ventilation. We have been analyzing the heat disorder problem since the accident in order to come up with a solution to prevent future heat disorder incidents among Fukushima Daiichi NPP accident clean-up workers. METHODS: From March 22 to September 16, 2011, the Fukushima Labor Bureau assessed 43 cases of nuclear power plant workers with heat disorders. Age of subject, month and time of occurrence, temperature, and humidity were examined for each case, as well as the severity of heat disorders. The grade of severity was divided into Grade I and Grade II or higher. Then, age, temperature, and humidity were analyzed using the Mann-Whitney Utest, and age, temperature, humidity, and presence or absence of a cool-vest were analyzed using the χ(2) test and logistic regression analysis. SPSS version 17.0 statistical software was used with a level of significance of p< 0.05. RESULTS: Heat disorders occurred most frequently in subjects in their 40s (30.2%), followed by those in their 30s (25.6%), mostly in July (46.5%) between 7 am and 12 pm (69.8%). Heat disorders occurred most frequently in environments with temperatures more than 25°C (76.7%) and humidity of 70-80% (39.5%). Heat disorders of Grade II or higher occurred in 10 cases, 5 of which were in June. According to statistical analysis, there were no significant differences in difference of severity for all factors. CONCLUSIONS: Heat disorders usually occur in workers aged 45-60; however, cases of heat disorders at the Fukushima Daiichi NPP occurred in clean-up workers at the relatively younger ages of 30-40, suggesting the need for heat disorder prevention measures for these younger workers. Heat disorder cases primarily occurred in the morning, necessitating preventive measures for the early hours of the day. In addition, because heat disorders of Grade II or higher occurred in June in 5 of 10 cases, we believe heat disorder precautions should be implemented from June. The lack of significant difference in severity difference may be attributable to the small number of cases or other factors. We think Fukushima Daiichi NPP accident clean-up workers need heat disorder prevention measures for their safety, based on the results of this study.

    OBJECTIVES: Some heavy metals are suspected to be pathogenic to both Parkinson's disease (PD) and depression. Common background may exist in them. METHODS: Subjects comprised PD patients with depression, PD patients without depression and controls recruited from the outpatient clinic in China. Morning blood and urine samples were used to measure concentrations of metals and vitamins. RESULTS: Whole-blood manganese was significantly higher in the PD patients without depression than in both the PD patients with depression and the controls. Serum iron was significantly higher in the PD patients without depression than in the controls. Urine iron was also significantly higher in the PD patients without depression than in the controls. Serum copper was significantly lower in the PD patients with depression than in both the PD patients without depression and the controls. CONCLUSIONS: Excessive intake of iron and accumulation of manganese seemed to be involved in the etiology of non-depressive PD.

    BACKGROUND: During and after the Fukushima nuclear disaster (FND), many parents were concerned about the effects of radiation on the health of their children. PURPOSE: To clarify the factors that influenced general workers living with children and the effect of child age groups in implementing preventive behaviorsagainst radiation following the FND. MATERIALS AND METHODS: A descriptive study of preventive behaviors among general workers was carried out 3-5 months after the nuclear disaster. The subjects were 1,394 regular workers, who took part in radiation seminars run by the Fukushima Occupational Health Promotion Center between July and September, 2011. In total, 1,217 responses were submitted, of which 1,110 were eligible for the present study. This anonymous questionnaire survey inquired about the presence and age of children in the household and about radiation preventive behavior implemented after the FND. The contribution of each variable was assessed by logistic regression analysis. RESULTS: General workers in Fukushima who lived with younger children performed more preventive behavior against radiation during and after the FND. In particular, both location-related and daily routines were practiced significantly more frequently (p<0.01) by workers living with a child in the age ranges of 0-6 (8 of 10 items) and 7-12 (5 of 10 items). CONCLUSIONS: This is the first study to assess the positive association between living with children by age group and increased preventive behavior against radiation implemented by general workers after the FND.

    Objective: It is well known that manganese (Mn) exposure is involved in parkinsonism. The aim of our study was to test the hypotheses that Mn affects nicotinamide N-methyltransferase (NNMT) activity, increases the metabolism of nicotinamide (NA) to 1-methylnicotinamide (MNA), and leads to neurocytotoxicity. Methods: Following demonstration of the effects of Mn concentrations on the survival rate of Mouse CD1 brain striatum neuronal cells (MS cells), the effect of Mn on NNMT activity was investigated by comparing the difference in the amount of MNA produced after various Mn concentrations were added to mouse brain cytosol fractions as an enzyme solution. Toxicity induced by MNA and its precursor NA on MS cells was measured. Results: The survival rate of MS cells decreased significantly with increasing concentrations of Mn in the culture medium. With respect to the influence of Mn on NNMT activity, NNMT activity increased significantly at Mn concentrations of 1 lmol/mg protein. MNA and NA neurotoxicity were compared by comparing cell survival rate. Cell survival rate dropped significantly when the cells were cultivated with 10 mM of MNA. There was also a tendency for the survival rate to fall following the addition of 10 mM NA
    however, the difference with the control was not significant. Conclusions: Our study suggests the possibility that Mn causes increased NNMT activity, thereby increasing MNA levels in the brain and bringing about neuron death. Daily absorption of Mn and NA may thus contribute to idiopathic Parkinson's disease. © The Japanese Society for Hygiene 2012.

    A 10-year follow-up cohort study of 4,535 National Health Insurance beneficiaries aged 40 to 69 years in Shiga was performed as part of a research project conducted by the Health Promotion Research Committee of the Shiga National Health Insurance Organizations in 2002. The relationship between cardiovascular risk factors and medical expenditures during the 10-year study period has been examined in this cohort. For example, there was a positively graded correlation between blood pressure and individual total medical expenditures per month. The odds ratio for cumulative hospitalization and hazard ratio for all-cause mortality in severe hypertensives were also higher than those in normotensives. However, from the viewpoint of the entire population, the excess medical expenditures attributable to hypertension within the total medical expenditures were higher for mild-to-moderate hypertensives than for severe hypertensives. On the other hand, although individual medical expenditures per month were 1.7-fold higher for participants with 2 or 3 risk factors and obesity, which was broadly equivalent to metabolic syndrome, than for those without these factors, the excess medical expenditures determined by risk clustering within the total medical expenditures were higher in normal-weight people than in obese people because of the higher prevalence of normal weight. These findings suggest that high-risk individuals are a good target of a high-risk approach, such as intensive health guidance, from the viewpoint of medical expenditures. However, another approach for the majority with a low-to-moderate cardiovascular risk should be considered, because they account for a greater proportion of the excess medical expenditures. Another way to solve this problem may be a population approach with an effective method of providing information to citizens.

    OBJECTIVE: The possibility that smoking prevalence among junior and senior high school students may decrease with increasing mobile phone bill was reported by the mass media in Japan. We conducted a nationwide survey on adolescent smoking and mobile phone use in Japan in order to assess the hypothesis that mobile phone use has replaced smoking. METHODS: A total of 70 junior high schools (response rate; 71%), and 69 high schools (90%) from all over Japan responded to 2005 survey. Students in the responding schools were asked to fill out an anonymous questionnaire about smoking behavior, mobile phone bill, and pocket money. Questionnaires were collected from 32,615 junior high school students and 48,707 senior high school students. RESULTS: The smoking prevalence of students with high mobile phone bill was more likely to be high, and that of students who used mobile phones costing 10,000 yen and over per month was especially high. When "quitters" were defined as students who had tried smoking but were not smoking at the time of survey, the proportion of quitters decreased as the mobile phone bill increased. The proportion of students who had smoking friends increased with the increase in the mobile phone bill per month. CONCLUSION: The hypothesis that the decrease in smoking prevalence among Japanese adolescents that has been observed in recent years is due to a mobile phone use can be rejected.

    Study Objective: The objective of this study was to examine the association between the use of mobile phones after lights out and sleep disturbances among Japanese adolescents.Design and Setting: This study was designed as a cross-sectional survey. The targets were students attending junior and senior high schools throughout Japan. Sample schools were selected by cluster sampling. Self-reported anonymous questionnaires were sent to schools for all students to fill out.Participants: A total of 95,680 adolescents responded. The overall response rate was 62.9%, and 94,777 questionnaires were subjected to analysis.Intervention: N/AMeasurements and Results: Daily mobile phone use, even if only for a brief moment everyday, was reported by 84.4%. Moreover, as for use of mobile phones after lights out, 8.3% reported using their mobile phone for calling every day and 17.6% reported using it for sending text messages every day. Multiple logistic regression analysis showed that mobile phone use for calling and for sending text messages after lights out was associated with sleep disturbances (short sleep duration, subjective poor sleep quality, excessive daytime sleepiness, and insomnia symptoms) independent of covariates and independent of each other.Conclusion: This study showed that the use of mobile phones for calling and for sending text messages after lights out is associated with sleep disturbances among Japanese adolescents. However, there were some limitations, such as small effect sizes, in this study. More studies that examine the details of this association are necessary to establish strategies for sleep hygine in the future.

    Purpose. To describe differences in physical activity in the context of clustering patterns of health-promoting behaviors.
    Design. A cross-sectional study with 1 724 participants (response rate, 91.1%).
    Setting. Tadami Town, in a rural area of Fukushima Prefecture, japan.
    Subjects. Part of the general population who participated in annual health checkups (age range, 30-93 years).
    Measures. The Health-Promoting Lifestyle Profile II was used to assess frequency of health-promoting behaviors (physical activity, health responsibility, spiritual growth, interpersonal relationships, nutrition, and stress management). Smoking status, alcohol consumption, and disease status were self reported. Public health nurses measured the weight and height of participants.
    Analysis. Cluster analysis was conducted to identify clustering patterns of health-promoting behaviors other than physical activity. Differences in. physical activity between identified clusters were examined by multiple logistic regression analysis.
    Results. Four clusters were identified and labeled as "Most challenged" (20.4%), "Adherence to norms" (30.3 %), "Well in mentality" (20.9%), and "Health-promoting" (28.4%). "Health-promoting" was the most physically active cluster, followed by "Adherence to norms" and "Well in mentality."
    Conclusions. Although the survey methodology was subject to selection, self-report, and recall biases, we have described physical activity in the context of clustering patterns of health-promoting behaviors. Laying the groundwork for physical activity in the lifestyle is important for establishing health-promotion strategies to increase physical activity. (Am J Health Promot 2011;25 [6]:410-416.)

    Background Proper age verification can prevent minors from accessing tobacco products. For this reason, electronic locking devices based on a proof-of age system utilising cards were installed in almost every tobacco vending machine across Japan and Germany to restrict sales to minors.Objective We aimed to clarify the associations between amount smoked by high school students and the usage of age verification cards by conducting a nationwide cross-sectional survey of students in Japan.Methods This survey was conducted in 2008. We asked high school students, aged 13-18 years, in Japan about their smoking behaviour, where they purchase cigarettes, if or if not they have used age verification cards, and if yes, how they obtained this card.Results As the amount smoked increased, the prevalence of purchasing cigarettes from vending machines also rose for both males and females. The percentage of those with experience of using an age verification card was also higher among those who smoked more. Somebody outside of family was the top source of obtaining cards. Surprisingly, around 5% of males and females belonging to the group with highest smoking levels applied for cards themselves.Conclusions Age verification cards cannot fully prevent minors from accessing tobacco products. These findings suggest that a total ban of tobacco vending machines, not an age verification system, is needed to prevent sales to minors.

    Objective: The objective of this study was to clarify the prevalence of nightmares and sleep paralysis and associated factors among Japanese adolescents.Methods: This study was designed as a cross-sectional sampling survey. The targets were junior and senior high schools throughout Japan. Self-reported anonymous questionnaires were sent to schools for all students to complete.Results: A total of 90,081 questionnaires were analyzed. The overall response rate was 62.6%, and the prevalence of nightmares and sleep paralysis was 35.2% and 8.3%, respectively. Multiple logistic analyses revealed that female sex, drinking alcohol, poor mental health, difficulty initiating sleep, low subjective sleep assessment, presence of excessive daytime sleepiness, and presence of sleep paralysis had higher odds ratios than others for nightmares. Male sex, poor mental health, drinking alcohol, taking a long daytime nap, early or late bedtime, difficulty initiating sleep, low subjective sleep assessment, presence of excessive daytime sleepiness, and presence of nightmares had higher odds ratios than other factors for sleep paralysis.Conclusions: This study has revealed the prevalence of nightmares and sleep paralysis among Japanese adolescents. Furthermore, the results of this study suggest that it is important to maintain regular sleep habits for preventing these symptoms. We propose that health education about regular sleep habits should be promoted among Japanese adolescents. (C) 2010 Elsevier B.V. All rights reserved.

    Aim: The World Health Organization (WHO) includes insulin resistance among its criteria for diagnosing metabolic syndrome (MetS); however, previous epidemiologic studies have limited their research to settled populations only. This study aims to clarify the relationship between plasma insulin and metabolic factors on a broader scale by studying data obtained from nomadic and settled Mongolian populations.
    Methods: A cross-sectional epidemiologic study of 200 nomads and 256 farmers was performed in Inner Mongolia, Republic of China. Plasma insulin levels and other metabolic factors, such as blood pressure, serum lipids and obesity, were measured. Participants were classified into 3 categories according to their plasma insulin levels.
    Results: Cut-off values grouped into tertiles of fasting insulin for all participants were 6.73 nmol/L and 10.33 nmol/L. The mean number of metabolic risk factors, waist circumference, fasting plasma glucose and triglyceride were higher, and the mean HDL cholesterol was lower in the higher fasting insulin tertile among farmers after adjusting for age, gender, smoking, alcohol drinking and total cholesterol. However, no MetS factors were statistically related with fasting insulin tertile levels among nomads.
    Conclusions: In nomads, hyperinsulinemia may not be an indicator of MetS due to their specific lifestyle.

    Although a number of previous studies have examined the prevalence of excessive daytime sleepiness (EDS) among adolescents, there have been very few nationwide studies. Therefore, we conducted a cross-sectional nationwide study to clarify the prevalence of EDS and associated factors among Japanese adolescents. The survey was performed from December 2007 to March 2008 on students enrolled in randomly selected junior and senior high schools throughout Japan, using self-administered questionnaires. Of 90 361 questionnaires collected, 87 233 were analyzed. The Japanese version of the Epworth Sleepiness Scale (JESS) was used to measure EDS, which was defined as a JESS score of > 10. The prevalence (and 95% confidence interval) of EDS among males was 28.1% (27.7-28.5%), and that among females was 38.4% (37.9-38.9%). Multivariate analysis revealed that female sex, higher school grade, poor assessment of subjective sleep, late bedtime, parasomnia symptoms, long commuting time, poor mental health, drinking alcohol, smoking, and participating in extracurricular activities had significantly higher odds ratios for EDS. In conclusion, EDS in Japanese adolescents is common and associated with multiple factors.

    Background: The aim of the present study was to determine the prevalence of and factors associated with smoking among Japanese medical students, to help promote effective antismoking measures in this population.Methods: From the 80 university medical schools in Japan, 20 were randomly selected and invited to participate in our survey. The survey focused on medical students and employed an anonymous self-administered questionnaire. Information on each university's antismoking measures was obtained using a separate questionnaire administered to teaching stall The survey was conducted from December 2006 through March 2007. Factors associated with smoking were identified by using the chi-square test and multiple logistic regression analysis.Results: A total of 1619 valid surveys were returned. The overall prevalence of smoking was 13.7% (18.1% among men and 5.1% among women). Factors associated with smoking among medical students were male sex, enrollment at a private medical university, smoking by siblings, alcohol consumption, coffee consumption, insomnia, and less than 6 hours of sleep per night.Conclusions: Antismoking education must be further promoted to Japanese medical students, with consideration given to the factors associated with smoking behavior found in the present study.

    Study Objective: Pregnant women suffer from sleep disturbance, which may be aggravated by passive smoking. In this study we investigated the effects of passive smoking on sleep disturbance during pregnancy.Design: Two cross-sectional questionnaire surveys conducted in 2002 and 2006.Setting: Clinical institutions specializing in obstetrics and gynecology that participated in the nationwide surveys: 260 in the 2002 survey and 344 in the 2006 survey.Participants: 16,396 and 19,386 pregnant women in Japan surveyed in 2002 and 2006, respectively.Intervention: N/A.Measurements and Results: Pregnant women exposed to passive smoking were likely to have sleep disturbances, such as subjective insufficient sleep, difficulty in initiating sleep, short sleep duration, and snoring loudly/breathing uncomfortably. Smoking pregnant women had the same sleep disturbances and also experienced excessive daytime sleepiness and early morning awakening, The prevalence of 5 types of sleep disturbance (insufficient sleep, difficulty in initiating sleep, short sleep duration, excessive daytime sleepiness, and snoring loudly/breathing uncomfortably) among nonsmokers with environmental tobacco smoke showed a mean value intermediate between that of active smokers and that of nonsmokers without environmental tobacco smoke.Conclusion: Passive smoking is independently associated with increased sleep disturbance during pregnancy.

    OBJECTIVE: The purpose of this study is to determine whether the statistics from three published reports on Parkinson's disease (PD) are mutually interrelated and to clarify the relationship between the prevalence statistics and mortality statistics of PD. These statistics included data on "number of patients with PD (PD Patients)", "number of patients with PD receiving financial aid for treatment (PD Recipients)" as an indicator showing the prevalence of PD, and "number of deaths from PD (PD Deaths, i.e., mortality)". METHODS: The data on PD Patients, PD Recipients and PD Deaths were cited from "Patient Survey" by Ministry of Health, Labour and Welfare, a report by the Research Committee on Epidemiology of Intractable Diseases and "Vital Statistics of Japan" by Ministry of Health, Labour and Welfare, respectively. The expected PD Patients, PD Recipients and PD Deaths were calculated as products of their respective rates for the entire country and prefecture population, adjusting for a difference in population composition. Observed/expected number ratios (O/E ratio) of PD Patients, PD Recipients and PD Patients were calculated by prefecture. The correlation between the O/E ratios was examined. In addition, the relationships of the O/E ratios with the number of hospitals or physicians per person were examined. RESULTS: There were no significant correlations between the O/E ratios of PD Patients, PD Recipients or PD Deaths. The O/E ratio of PD Recipients significantly correlated with the numbers of hospitals and physicians per person. CONCLUSION: PD Patients and PD Recipients were included in number of people with PD and PD Deaths was derived from people with PD. However, these statistics do not necessarily reflect the prevalence of PD in each prefecture. When using these published statistics as an indicator of the prevalence of PD, it is necessary to clarify the purpose of their use and to comprehend their characteristics.

    &lt;p&gt;There are few community-based epidemiologic studies that have dealt with risk factors for heart failure in non-Western populations. It has been reported that the measurement of plasma B-type natriuretic peptide (BNP) is useful for detecting patients with asymptomatic heart failure. To clarify the determinants of high plasma BNP level, the association of BNP with cardiovascular risk factors in community dwelling residents was examined. The plasma BNP levels were measured in 686 residents aged 35-69 years who received annual health check-up. The relationship of BNP to blood pressure, blood haemoglobin, serum cholesterol (total and high-density lipoprotein cholesterol), plasma glucose, electrocardiographic (ECG) findings, urinary salt excretion, and lifestyle factors (smoking and alcohol consumption) were cross-sectionally analysed. The plasma BNP geometric mean was 13.7 pg/ml. Both linear and logistic regression analyses indicated that the plasma BNP levels were positively associated with age, urinary salt excretion, higher blood pressure, high R-wave voltage in the 12-lead ECG (Minnesota Code 3-1 or 3-3), and female gender. Plasma BNP levels were inversely associated with blood h

    虚血性心疾患は米国において死亡原因の第一位であり,1999年の死亡者数53万人,内25万人は病院外死亡であり,そのほとんどは心突然死である。心突然死の内,以前より虚血性心疾患の症状を認めるものは半数に満たない。古典的危険因子(コレステロール,喫煙,血圧,糖尿病)は,明らかにリスクの高い者,また低い者を選別する上で有効であるが,大部分の者はどちらでもない中間層に分類されるため,一般住民を対象としたスクリーニング手段としては不十分である。これは,同一レベルの危険因子を有していても,危険因子への曝露期間,古典的危険因子以外の危険因子,遺伝子多型,遺伝子と環境因子との相互作用等の影響と考えられ,危険因子そのものよりも,危険因子への曝露の結果である潜在的動脈硬化所見を用ることで,より有効に発症予測,予防を行い得る可能性が検討されている。<br/> 電子ビームコンピュータ断層撮影(EBCT)による冠状動脈石灰化の測定は非侵襲的に冠状動脈の潜在的動脈硬化を定量出来,一般住民を対象とした虚血性心疾患の初回発症予防におけるスクリーニングの手段として,米国で注目されている。本論文では,EBCT の意義,また初回発症予防における EBCT の有効性を評価した疫学研究を概説した。EBCT は非常に有用である可能性があるものの,現状では,十分な結論が得られていない。<br/> 日本における虚血性心疾患死亡率は先進国の中でいまだ低いが,戦後世代である,30歳代,40歳代の男性に焦点を当てると,日米において,血圧,コレステロール値に関して大きな差はなく,また日本の喫煙率は米国の約 2 倍である。さらに,日本の剖検による検討からは,男性の20-30歳代で動脈硬化が増加していることが指摘されている。日本において,戦後世代の一般住民における,潜在性動脈硬化の程度を評価し,かつ,米国の一般住民と比較することは,日本の虚血性心疾患の今後の動向を予測する上で非常に重要であると考えられ,その評価手段として EBCT は非常に有用であると思われる。

    Objectives: To assess trends in smoking prevalence among Japanese adolescents and to analyze possible causal factors for the decrease in smoking prevalence observed in a 2004 survey. Methods: Nationwide cross-sectional surveys were conducted in 1996, 2000 and 2004. Survey schools, both junior and senior high schools, considered to be representative of the whole of Japan were sampled randomly. Enrolled students were asked to complete a self-reporting anonymous questionnaire on smoking behavior. The questionnaires were collected from 115,814 students in 1996, 106,297 in 2000, and 102,451 in 2004. School principals were asked about the policy of their respective school on smoking restrictions. Results: Cigarette smoking prevalence (lifetime, current, and daily smoking) in 2004, based on the completed questionaires, had decreased relative to previous years in both sexes and in all school grades. The most important trends were: a decrease in smoking prevalence among the fathers and older brothers of the students
    an increase in the proportion of students who did not have friends
    a decrease in the proportion of current smokers who usually bought cigarettes in stores decreased in 2004, in particular for the oldest boys. An association was found between a lower smoking rate at a school and a smoke-free school policy. Conclusions: Japan has experienced a decrease in the prevalence of smoking among adolescents. A decrease in smoking prevalence among the fathers and older brothers, limitations to minors' access to tobacco, an increase in the proportion of students without friends, and a school policy restricting smoking may have contributed to this decreasing trend. © 2008 The Japanese Society for Hygiene.

    Background Although obesity is required for some criteria defining metabolic syndrome, clustering of other risk factors also indicates an increased risk of cardiovascular disease. Whether the relationship between cardiovascular risk factor clustering and medical expenditures differs with body mass index (BMI) requires investigation, especially in a population with a low prevalence of obesity such as that in Japan.
    Methods and Results A 10-year cohort study of 4,478 Japanese National Health Insurance beneficiaries aged 40-69 years in a community between 1990 and 2001 was carried out in the present study. The clustering of cardiovascular risk factors showed a positive and graded relationship to personal medical expenditures in participants who are overweight (BMI &gt;= 25.0) and normal weight (BMI &lt;25.0). The individual medical expenditures per month were 1.7-fold higher for participants with 2 or 3 risk factors and overweight than for those without these factors (26,782 vs 15,377 Japanese yen). Differences in the geometric means were similarly significant after adjustment for other confounding factors. However, the excess medical expenditures by risk clustering of normal weight categories within the total medical expenditures were higher than those of overweight categories because more participants were of normal weight.
    Conclusions Cardiovascular risk factor clustering and being overweight can be a useful predictor of medical expenditures in a Japanese population.

    インターネット普及に伴い、インターネット依存による昼夜逆転やうつ状態などの精神的問題が世界中で報告されている。また、スマートフォンなどの使用による頭部前傾の影響によって、頸椎の早期摩耗や破損、変形に関与する可能性が示唆されている。さらに、近年新しく提案されてきた疾病概念に、頸性うつ状態がある。新しい時代の健康課題として、インターネット依存と抑うつ状態、頸部負荷の関係性の解明に際し、特に過労状況になりやすい学校教職員において、これらの関連を明らかにすることは予防医学上、重要な意味をもつ。
    平成30年度は、全国調査に向けた予備調査を行った。隣接する2つの県をモデルとし、両県内で中学校・高校を全数に対し、所属する全教職員を対象に、インターネット使用状況と頸部障害および抑うつ状態の実態に関するプレテストを行い、インターネット依存や頸性うつ状態などの有病率を予備的に明らかにすることを目的とした。
    調査票の回収状況は、モデル2県の中学校・高校総数241校に対し、119校より協力が得られた(学校回答率49.4%)。教職員個別の質問票回収状況は、対象者9990人に対し、回答3314人であった(回答率33.2%)。私用目的でのインターネット使用状況として、平日利用時間は30分未満が最多であったが、休日の利用時間は30分以上59分未満が最多となり、6時間以上の利用者が13.0%みられた。続いて、頸部痛に関連する項目として、自覚的な頸部痛の有訴率は32.6%であり、物の持ち上げ・読書・車運転への影響がある者は約15%程度にみられた。抑うつにつながる勤労意欲に関する項目では、仕事への活力や熱心さなどの項目において、およそ20%前後に自身の意欲を感じないことがあることが分かった。
    本研究で、インターネット依存や頸性うつ状態などの有病率を予備的に明らかにできた。今後詳細な検討を加える予定である。

    本研究の最終目的は,地域包括ケアシステムおいて介護老人保健施設(以下,老健とする)を核として地域の中で最期までをその人らしく生き抜くことを支える看取りケアモデルの開発である。
    昨年度に引き続き,今年度は3事例について検討を重ねた<研究課題1>。検討するにあたり,次の4点について意図的に振り返り,分析をした【1.高齢者本人と家族の状況を初回入所(サービス利用開始)から経時的に整理する,2.疾患や障害による身体の変化,ADLの変化をみる(変化をみながら,加齢による影響も分析),3.看取りの時期であると判断した状況・時期を捉える,4.高齢者本人や家族に対し誰がどのようなかかわりを行ったのか実際を整理する】。
    3事例は80歳代~90歳代で,地域の中で(いつもの暮らしの中で)老健(通所リハ,ショートステイ,入所)を活用しながら生活をしていた。夫婦で生活していた事例もあったが,最期は全員が独り身であった。徐々に身体が衰えても,自宅で生活する可能性を多職種で検討し,帰るタイミングを探っていた。老いや疾患に対する体調管理,退所前訪問/退所後訪問により福祉用具・医療機器の導入や移動・排泄動作などの確認・練習,緊急時の連絡・対応方法の確認等を行い,本人・家族の心配事や困り事に対処していた。老健内での過ごし方は様々であり,誰とどのように過ごしていたのかは重要な視点であることを確認した。
    1事例は,夜間の急変により病院で亡くなっており,看護職・介護職に後悔がみられた。①看護師の判断,②病院スタッフとのコミュニケーションの内容(本人の意思の反映,治療による回復の見通し等),③老健の受け入れ状況,④看取り後のカンファレンスの持ち方について,課題が見いだされた。
    今後は,事例検討とアクション・リサーチを重ね,「高齢者の看取りケア指標」の要素を抽出し,指標の考案,調査に繋げる予定である<研究課題2>。

    本研究は、第13次労働災害防止計画上も重点業種としても挙げられている陸上貨物運送業のうち、中小規模の運送業のドライバーの健康支援を目的として、支援のためのしくみやモデルを構築することを目指している。特に運行管理者に着目した支援モデルを想定して進めている。2018年度は、以下の研究活動を行った。
    1.首都圏の3か所のトラック協会及び産業保健総合支援センターの協力を得て、主には運行管理者を対象としたアンケート調査を実施した(期間:2018年7月~2019年2月)。アンケート300部回収(回収率62.4%)し、運行管理者の健康支援に繋がる関わりの程度や困難感について分析を行った。運行管理者はコミュニケーションを密にとりながら積極的にかかわっている実態が明らかになり、かなりドライバーへの支援的な役割を担っていることがわかった。また一方で、支援的な役割を担いながらも、具体的な助言や対応への困難感が強いことも明らかになった。運行管理者負担軽減や問題対応支援の為にも外部支援者との円滑な連携が大きな課題であることが示唆された。(島本ら,2018:調査の一部報告)
    2.1の結果をもって、50人未満の事業所の産業保健の支援を担う、地域産業保健推進センターの保健師や、中小企業の健康支援を行う開業産業医と意見交換を行った。教育の内容や現実的な課題について具体的な意見交換になった。2019年度以降に構築する、支援ツールや支援モデル開発へ反映させる予定である。

    平成19年度は,平成18年度に本研究に参加した地域一般壮年男性に対して,介入群・非介入群の割付に関わらず対象者全員に12ケ月後(平成19年7-8月)の時点でベースライン時と同様の健康診断検査および生活習慣に関する問診を行った。介入の評価として,メインアウトカムを両群におけるBNP平均値および高BNP者の頻度とし,サブアウトカムを血圧水準,高血圧の有病率,総コレステロール値,高コレステロール血症の有病率,喫煙率,多量飲酒者の割合,肥満度(BMI),生活習慣の変化,心不全に関する自覚症状とした。結果,メインアウトカムに関し,BNP平均値および高BNP者の頻度は,非介入群でBNP平均値の上昇,高BNP者の頻度の増加がみられる一方,介入群でBNP平均値の維持,高BNP者の頻度の維持の傾向がみられたが,統計的有意差を得ることは出来なかった。サブアウトカムについては今後詳細な分析を行っていく予定である。
    また対象者のうち,平成18年度の割付で非介入群の中から血圧管理指導等の保健介入実施の強い要望が寄せられたため,cross-over designとし,介入群・非介入群を入れ替えて保健介入を行った。介入群には血圧管理に関する保健指導・生活指導を、非介入群には禁煙指導・メンタルヘルス指導を行った。

    近年、本態性(老人性)痴呆症の発症や病態のメカニズムが明らかにされるにつれ、脳機能低下を予防させるために、より早期に精神機能の低下の兆候を特定することに注目が集まってきている。従来我が国において実施されてきた痴呆症対策は、痴呆がある程度のレベル以上に進行してしまっているため、改善が極めて困難な状態の痴呆症に対する医療・リハビリテーションによるケアであった。そこで、我々は島根県H町在住の初老期以降(50歳以上)の地域住民について、二段階方式診断法を用いた軽症痴呆症の評価法及び脳活性化対策の有効性を検討し、次のような結果が得られた。
    1)性・年代別かなひろいテスト得点では、女性において加齢による得点の低下が見られた。
    2)本研究では二段階方式診断法を用いて参加者58名のうち前痴呆8名、軽症痴呆4名であった。
    3)かなひろいテストの得点とMMSの得点との相関係数は0.6868で、正の相関が認められた。
    4)脳活性化対策実施後で60歳代男性を除いて全ての性・年代別で教室前のかなひろいテスト得点を上回った。
    5)脳活性化対策の継続実施は教室前の状態に比べ痴呆状態を改善しうることが明らかになった。特に、対策開始後2年間継続によって、かなひろいテスト平均得点の上昇がピークに達することが分かった。
    6)ライフスタイル調査では、重点対策前と対策開始1年後で参加者の日常生活に、ADLや対外的な行動に大きな割合の変化は無かった。
    7)参加者の痴呆に関する意識では、対策開始後1年でアンケートに14名全てが「自分は痴呆にならないと思う」と回答した。
