Outline of Final Research Achievements

We performed cross-sectional studies on the relationship between job stress and the results of medical checkups (obesity, high blood pressure and impaired glucose tolerance) conducted in 1996 and in 2002 in a metal products factory, and on some health-related habits (smoking, alcohol intake and physical exercise). There were 6238 subjects, with a mean age and standard deviation of 39.4±10.6 years in 1996, and 6430 and 42.0±11.0 years, respectively. The high job control group compared with the low job control group showed a higher percentage of physical exercise of one or more times per week in both the 1996 and 2002 studies.
After adjustment for several confounding factors, we found no significant association between job stress and survival rate either in the 1996 (6173 subjects, 18.9±4.9 year observation period) or 2002 studies (6347 subjects, 13.7±3.2 year observation period).

Academic Significance and Societal Importance of the Research Achievements

職業性ストレス増加は働く人の健康障害と関係が深いが、その長期的影響を生存率で検討した場合、従来から言われている血圧上昇、耐糖能異常、喫煙などの影響が大きく、職業性ストレスの影響は小さい。
