| Research Abstract |
(1)In 2002, we collected baseline data from medical records of 22128 men who attended a checkup in a medical center. The data includes indices (present/past medical history, body height/weight, blood pressure, blood glucose, serum triglycerides and HDL-cholesterol)related to insulin-resistance syndrome≒metabolic syndrome (MS : diagnosed by four MS-factors : 1)obesity, 2)high blood pressure, 3)high blood glucose and 4)dyslipidemia), confounding factors (age, lifestyle and other blood indices) and occupational factors (job title, work-day, work-hour, holiday, work-system and work-activity). Same data from 14614, 17953 and 18066 men were collected in 2003, 2004 and 2005, respectively. All the data have been accumulated in a data base.
(2)Out of 22128 men in 2002, 15242 workers were selected as 'baseline healthy subjects' using the six following eligibility criteria; 1)age: 30-59 years, 2)full-time workers, 3)no present disease or medical treatment, 4)no history of diabetes, hypertension, h

yperlipidemia or malignancy, 5)fasted blood sample without hemolysis and 6)complete data on all required factors. In the 15242 workers, A)policemen/firefighters, service workers, manager/administrative workers, B)almost everyday working, C)short work-time per day (the results are probably due to older subjects). D)night workers, E)low work-activity were related with higher prevalence of the four MS-factors and MS.
(3)Out of the 15242 workers, 6739 workers had followed-up data after 3 years. In the 6739 workers, the prevalence of the four MS-factors have increased during the 3 years (+83 to +241 subjects). However, MS-factors and MS have decreased in some subjects. Relations of the changes in the prevalence of MS-factors with occupational factors will be fully analyzed. Age and lifestyle (drinking, smoking and exercise) are used as confounding factors in further analysis of data in(2)and(3).
(4)We carried out follow-up studies on incidence of diabetes (fasted blood glucose【greater than or equal】126mg/dl or medical treatment for diabetes during the follow-up) using past medical records accumulated (from 1988 to 2000) in the medical center, and the results have been presented in medical conferences and published in medical journals.
