“…The duration of followup for incident type 2 diabetes ranged from 2.5 to 16 years, with a median follow-up of 7.5 years. Five studies were conducted in the U.S. (14,17,(20)(21)(22), two in Europe (15,18), two in Asia (16,19), and one in Australia (13). Sleep duration was assessed by questionnaire in all studies.…”

“…Sleep duration was assessed by questionnaire in all studies. In six studies (13)(14)(15)17,20,21), type 2 diabetes was ascertained by medical records or selfreports; the outcome of four studies (16,18,19,22) was assessed by means of a fasting plasma glucose or a glucose tolerance test. One study was a substudy of a prospective lifestyle intervention trial (18), and the remaining nine were prospective cohort studies.…”

“…In addition, without a dose-response analysis, it remains unknown how many hours of habitual sleep are associated with the lowest risk of type 2 diabetes. In the past several years, the number of prospective studies with enough quantitative categories has nearly doubled (13)(14)(15)(16)(17)(18)(19)(20)(21)(22). Therefore, we conducted a meta-analysis of prospective studies to determine the overall shape of the relationship between sleep duration and risk of type 2 diabetes.…”

OBJECTIVEIt remains unclear how many hours of sleep are associated with the lowest risk of type 2 diabetes. This meta-analysis was performed to assess the dose-response relationship between sleep duration and risk of type 2 diabetes. RESEARCH DESIGN AND METHODSPubMed and Embase were searched up to 20 March 2014 for prospective observational studies that assessed the relationship of sleep duration and risk of type 2 diabetes. Both semiparametric and parametric methods were used. RESULTSTen articles with 11 reports were eligible for inclusion in the meta-analysis. A total of 18,443 incident cases of type 2 diabetes were ascertained among 482,502 participants with follow-up periods ranging from 2.5 to 16 years. A U-shaped dose-response relationship was observed between sleep duration and risk of type 2 diabetes, with the lowest risk observed at a sleep duration category of 7-8 h per day. Compared with 7-h sleep duration per day, the pooled relative risks for type 2 diabetes were 1.09 (95% CI 1.04-1.15) for each 1-h shorter sleep duration among individuals who slept <7 h per day and 1.14 (1.03-1.26) for each 1-h increment of sleep duration among individuals with longer sleep duration.

“…Insomnia sometimes occurs as a primary disorder and sometimes as a secondary disorder associated with other diseases. 20 Insomnia is also known to be a risk factor for mental and physical disorders, [22][23][24][25] and to increase the risk of mortality. 26 Therefore, development of countermeasures against insomnia in physicians is essential for both the management and promotion of health in physicians.…”

Objective:The aim of the present study was to clarify the current work and sleep situations of physicians in Japan and to clarify the association between these situations and excessive daytime sleepiness as well as medical incidents. Methods: A self-administered questionnaire survey was conducted among the members of the Japan Medical Association in 2008. The randomly selected subjects comprised 3,000 male physicians and 1,500 female physicians. Results: Valid responses were obtained from 3,486 physicians (2,298 men and 1,188 women). Mean sleep duration was 6 h 36 min for men and 6 h 8 min for women. The prevalence of lack of rest due to sleep deprivation was 30.4% among men and 36.6% among women; the prevalence of insomnia was 21.0% and 18.1%, respectively; and the prevalence of EDS was 3.5%. The adjusted odds ratio for EDS was high for physicians who reported short sleep duration, lack of rest due to sleep deprivation, and a high frequency of on-call/overnight work. Physicians who had experienced a medical incident within the previous one month accounted for 19.0% of participants. The adjusted odds ratio for medical incidents was high for those subjected to long working hours, high frequency of on-call/overnight works, lack of rest due to sleep deprivation, and insomnia. Conclusion: In order to facilitate optimal health management for physicians as well as securing medical safety, it is important to fully consider the work and sleep situations of physicians. keywords: Physicians, sleep duration, insomnia, excessive daytime sleepiness, medical incidents Citation: Kaneita Y; Ohida T.

Marital status is related to cardiovascular disease (CVD) risk factors in Western countries. However, few studies have addressed the relationship between marital status and CVD risk factors in other populations. We investigated lifestyle and CVD risk factors relative to marital status among middle-aged Japanese men. We analyzed baseline data of 40-59-yr-old male workers who participated in the high-risk and population strategy for occupational health promotion (HIPOP-OHP) study. We compared lifestyle and CVD risk factors between men who were married (Group M; n=1,419, mean age 47.9 ± 5.1 yr) and those who had never married (Group N; n=163, mean age 46.7 ± 4.3 yr). Men in Group N were more likely to skip breakfast, work more shifts and exercise less. Current smoking rates, as well as average values of diastolic blood pressure (DBP), serum total cholesterol and fasting plasma glucose were also higher in Group N than in Group M. The proportion of participants with three or more CVD risk factors, namely smoking, hypertension, hypercholesterolemia and hyperglycemia was higher in Group N, than in Group M (12.9% vs. 5.0%, p<0.01). The difference between Groups M and N was more evident in the subgroup of living with others, than in the subgroup of living alone. Since men who have never married might be at higher risk for CVD, effort should be made to educate this population about decreasing lifestyle-related risk factors. (J Occup Health 2008; 50: 348-356)

Relation between sleep quality and quantity, quality of life, and risk of developing diabetes in healthy workers in Japan: the High-risk and Population Strategy for Occupational Health Promotion (HIPOP-OHP) Study

Abstract: Background: The effect of sleep on the risk of developing diabetes has not been explored in an Asian population. The objective of this study is to investigate the effect of self-reported sleep duration and sleep quality on the risk of developing diabetes in a prospective cohort in Japan.
