<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<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 (&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>
<sec>
<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.

The Choosing Wisely Initiative and MRIs: Over- and Under-Diagnosis in Japan and Myanmar Reviewed

Takashi Watari, Tin Myo Hlaing, Hideyuki Kanda

Cureus 13 ( 4 ) 14342 2021.4

Language：English Publishing type：Research paper (scientific journal) Publisher：Cureus, Inc.

Recently, the "Choosing Wisely" initiative has gained traction and high-value care has garnered attention. However, the actual situation of high-value care is different between developed and developing countries. To elucidate this, we highlight the differences between the high-value care provided by healthcare systems in Japan and Myanmar, as representations of developed and developing countries, respectively. Despite the total numbers of magnetic resonance imaging (MRI) equipment in Japan being 400 times higher than in Myanmar, and gross domestic product per capita being 32 times higher in Japan, the individual costs (out of pocket expenditures) per MRI scan are the same (USD 60). However, the total cost per MRI scan is different, implying that differing healthcare costs indicate the existence of over- and under-diagnosis problems among different countries. This study suggests that detailed patient histories and physical examinations are important for selecting relevant diagnostic imaging and reducing unnecessary imaging.

Background: Sleep problems in adolescence, such as insomnia and short sleep duration, are associated with physical and mental health problems. However, little is known about the recent trends in sleep problems among adolescents. Therefore, this study examined trends in sleep problems among Japanese adolescents. Methods: Using data from the Lifestyle Survey of Adolescents collected in 2004 (n = 102,451), 2008 (n = 95,680), 2010 (n = 98,867), 2012 (n = 101,134), 2014 (n = 85,931), and 2017 (n = 64,417), we calculated the trends of insomnia, shorter sleep duration, late bedtimes, and poor sleep quality. Multivariable logistic regression analysis models were used to examine the association of each sleep problem and survey years. Findings: We analyzed data from 545,285 Japanese adolescents. Results indicated that, since 2004, the odds ratio for insomnia have decreased (Adjusted odds ratio [AOR] 0•85, 95% CI 0•82-0•87), as have the odds ratio for poor sleep quality (AOR 0•92, 95% CI 0•88-0•95). However, the odds ratio for shorter sleep duration (AOR 1•13, 95% CI 1•10-1•17) and late bedtimes tended to increase (AOR 1•06, 95% CI 1•03-1•08) during this period. Interpretation: The prevalence of insomnia symptoms and poor sleep quality among adolescents decreased from 2004 to 2017. However, there were increasing trends toward shorter sleep duration and late bedtimes. These changes are both relieving and concerning. Teachers, parents, and health professionals should consider educating adolescents regarding sleep hygiene, adjusting schedules of extracurricular activities, and enhancing time management to improve their sleep quantity. Funding: This study received funding from Japan's Ministry of Health, Labour and Welfare.
