The association of differences in occupational category and physical intensity on the results of health health examinations for cardiovascular diseases was studied was studied among industrial workers who were followed from 1980 to 1989. Subjects were 538 males and 242 females aged 35-44 years old in 1980. From responses to a questionnaire in 1980 subjects were classified into three occupational categories- “managerial officer or clerical worker”, “specialized technician” and “laborer” -then also into three categories according to level of physical intensity- “light”, “medium” and “heavy labor”. The following examination data from 1980 and 1989 were used : obesioy index, blood pressure, total cholesterol, β-lipoprotein, HDL-cholesterol, triglyceride, uric acid, fasting blood sugar. 1. In males, by occupational category, uric acid and triglyceride were higher in “managerial or clerical workers” than in others in both 1980 and 1989. By physical intensity category, while there were no significant differences in all data for males in 1980, uric acid, fasting blood sugar, total cholesterol, β-lipoprotein were higher in 1989 for the “light labor” group than others with significant differences in uric acid and fasting blood sugar. 2. By intensity categories, no significant differences were observed for female in 1980 in all data. However in 1989 diastolic blood pressure was significantly higher in the “light labor” group than others. From these results it appears that differences in occupational category in 1980 were not associated with difference observed in 1989 but that difference in physical intensity was associated with difference in some data in 1989.
