We examined whether the A1166C polymorphism of the angiotensin II type I receptor gene (AGTR1) affects cardiovascular event occurrence in a Japanese prospective cohort study. The 2212 participants who gave informed consent for genetic analysis were enrolled in this study (the Shigaraki Study). The average observation period was 1954 days. Cardiovascular events occurred in 37 individuals (1.7%). The independent factors which specified cardiovascular events were age (hazard ratio (HR)=1.13; 95% confidence interval (CI): 1.10-1.16; p<0.0001) and sex (HR=2.18; 95% CI: 1.23-3.85; p=0.007). However, the A1166C polymorphism of AGTR1 was not a predictive factor for cardiovascular events (HR=1.11; 95% CI: 0.61-2.02; p=0.731). (C) 2008 Elsevier Ireland Ltd. All rights reserved.

Trends in alcohol drinking prevalence were assessed among Japanese adolescents, and possible reasons for a decrease in drinking prevalence observed in 2004.Cross-sectional nationwide surveys were conducted periodically. High schools were randomly sampled from throughout Japan in 1996, 2000, and 2004. All enrolled students in sampled schools were subjects of the surveys. Self-reporting anonymous questionnaires were collected from 115,814 students in 1996, 106,297 in 2000, and 102,451 in 2004. Questions about drinking prevalence of students and family members, proportion of students who have no friends, and sources of alcohol were included. Students who drunk at least one day of the 30 days preceding the survey were defined as the current drinkers.The drinking prevalence in 2004 was decreased in comparison to that in 1996 and 2000 in both sexes and in all school grades. The current drinking rate (monthly drinker) among junior high school boys was 29.4% in 1996, 29.0% in 2000, and 20.5% in 2004, while that among senior high school boys was 49.7%, 48.7%, and 36.2%, respectively. The respective prevalence among junior and senior girls was 24.0%, 25.5%, and 20.0% and 40.8%, 42.1%, and 34.1%. The prevalent sources of alcohol beverages were searching in home, stores (convenience store, supermarket, or gas-stand), liquor shops, and bars. An analysis of the reasons for this decrease identified a decrease in drinking prevalence in students' families, especially by fathers and older brothers, and an increase in the proportion of students who had no friends.A decrease in drinking prevalence of male family members and a limitation of sources of alcoholic beverages may contribute to the decrease in adolescent drinking prevalence.

Language：English Publisher：Acoustical Society of Japan

A questionnaire survey and interviews were conducted among victims of the Mid-Niigata Earthquake from Yamakoshi village to elucidate the problems related to the living environment and the stressful experiences encountered by them in the temporary shelters. In this study we aim to clarify the relationships between environmental problems, including acoustic environment problems, and stressful experiences encountered in the temporary shelters, and we examine the impact of the acoustic environment of the temporary shelters on evacuee stress. Among the environmental problems (living space, temperature, illumination, acoustic environment, odor, and problems related to the shelter facilities and to maintaining privacy), the acoustic environment was the fifth most frequently cited environmental problem. However, a higher proportion of the participants who complained about the acoustic environment of the temporary shelters had stressful experiences than those who did not complain about the acoustic environment. These relationships were shown to be statistically significant by chi-square tests. It was found by logistic regression analyses that among the living environment problems, the acoustic environment was the most important factor in determining whether refugees found living conditions unpleasant and/or experienced stress. These results suggest that improvements to the acoustic environment of temporary shelters should lead to the mitigation of some evacuee stress.

Language：English Publishing type：Research paper (scientific journal)

BACKGROUND: For the Japanese population, a body mass index (BMI) of 25.0-29.9 is classified as obesity and is a risk factor for cardiovascular disorders such as hypertension. METHODS: A cohort study to clarify obesity costs for a Japanese population was conducted utilizing baseline BMI and medical costs over a 10-year follow-up period. The participants were 4502 community dwelling Japanese National Health Insurance (NHI) beneficiaries aged 40-69 years. According to their baseline BMI values (kg/m(2)), participants were classified into the following three categories: BMI < 18.5, 18.5 < or = BMI < 25.0 and 25.0 < or = BMI. Medical costs per person per month were compared among the three categories. Excess medical costs attributable to the 25.0 < or = BMI category compared to the 18.5 < or = BMI < 25.0 category were estimated. RESULTS: Approximately 20% of the Japanese population studied had a BMI of 25.0 or over. A J-shaped relationship between BMI and personal total medical costs was observed. Personal total medical costs per month determined from the 10-year follow-up in each category were 189 Euros (BMI < 18.5), 134 Euros (18.5 < or = BMI < 25.0) and 155 Euros (25.0 < or = BMI). A J-shaped pattern was observed after adjusting for age, sex, smoking and drinking habits, and excluding early deceased participants. Furthermore, smoking habit did not modify the J-shaped pattern of total medical costs. The estimated excess medical costs for the 25.0 < or = BMI category represented 3.1% of the total medical costs for the entire study population (634 105 Euros). CONCLUSION: The Japanese NHI beneficiaries with a BMI of 25.0 or over showed increased medical costs compared to those with a BMI of 18.5-24.9.

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.

1996、2000、2004年と3回実施された中学生5万人、高校生7万人を対象とした飲酒問題の全国調査の結果を検討した。その結果、中・高生の飲酒経験者は中学生で60%から40%に、高校生で75%から60%に減少し、中・高校生の1回あたりの飲酒量も減少し、飲酒による失敗経験も減少し、未成年飲酒禁止法への理解も高まっていた。中高生自身の酒の購入も減少し、アルコール濃度の低い甘い酒が多く飲まれるようになり、親から飲酒を勧められる経験も減少するなど、飲酒行動の変化が認められた。しかし、高リスクの問題飲酒群は男子はやや減少しているものの女子では減少していなかった。これらの減少傾向は、未成年者飲酒法の改正を中心とするこの10年間における未成年者飲酒に対する様々な政策や業界や世論の変化と、日本社会全体のアルコール消費量の減少傾向によるものと思われた。

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.

Objective: Previous epidemiological studies on relationships between mental health status and sleep status of adolescents have not been sufficiently representative. In the present study, using samples representative of Japanese adolescents associations between mental health nationwide, status and various sleep statuses were examined. Method: The survey was conducted in December 2004 and January 2005 among students enrolled in randomly selected junior and senior high schools throughout Japan using self-administered, questionnaires that addressed lifestyle, sleep status. mental health status, and personal data. Of 103.650 questionnaires collected, 99,668 were analyzed. Sleep status was assessed according to sleep duration, subjective sleep assessment, bedtime. and insomnia symptoms. The Japanese version of the 12-item General Health Questionnaire was employed for assessment of mental health status. Results: Mental health status of subjects whose sleep duration was less than 7 hours, and those who slept 9 hours or more, was poorer than that of subjects who slept for 7 hours or more but less than 9 hours. A U-shaped association was observed between mental health status and sleep duration. Furthermore, a linear association was observed between Subjective sleep assessment and mental health status; the worse the subjective sleep assessment. the poorer the mental health status. Mental health status was also inversely proportional to the frequency of insomnia symptoms. Conclusion: The fact that sleep duration and subjective sleep assessment showed different patterns of association with mental health status indicates that these 2 sleep parameters have independent significance. Considering these associations. it is important to promote mental health care and sleep hygiene education for adolescents.

On October 23, 2004, an earthquake inflicted heavy damage on the Mid-Niigata district. The earthquake isolated Yamakoshi village
consequently, all village residents were forced to evacuate to temporary shelters in neighboring Nagaoka city for two months. A questionnaire survey and interviews were conducted to elucidate problems related to the living environment in the temporary shelters. This study analyzed the relationships between problems related to the acoustic environment and stressful experiences. Among the environmental problems (size, temperature, illumination, acoustic environment and odor problems, and problems related to the shelter equipment and to maintaining privacy), the acoustic environment problems were the fifth most frequently cited environmental problems. A higher proportion of the participants who complained about the acoustic environment of the temporary shelters had stressful experiences, compared to those who did not complain about the acoustic environment. The tendency was statistically significant. Logistic regression analysis revealed that among the living environment problems, that of the acoustic environment was the most important factor for whether refugees felt uneasy, unpleasant, and/or stressed. These results suggested that improvements to the acoustic environment of temporary shelters should lead to some mitigation of refugees' stress.

Epidemiologic studies have investigated the relation between alcohol intake and coronary calcification, with controversial results. Furthermore, the influence of heavy drinking has not been well elucidated. In the present study, a random sample of community-based Japanese men aged 40 to 49 years without a history of cardiovascular disease (n = 245) were examined for coronary artery calcium (CAQ determined by electron-beam computed tomography and drinking status. There was a J-shaped association between alcohol intake and CAC. There was an increase of CAC in heavy drinkers (>= 46 g/day), and participants who were drinking >= 69 g/day showed a significant increase in CAC compared with never drinkers after adjusting for other cardiovascular risk factors.
