摘要：Mortality and Causes of Death among Japanese School Personnel between 1992 and 1996: Hideo TANAKA, et al. Department of Cancer Control and Statistics, Osaka Medical Center for Cancer and Cardiovascular Diseases —To examine mortality among Japanese school personnel working at primary and secondary schools, we studied mortality among members of the Mutual Aid Association of Public School Teachers (MAPST) aged 20 to 59 yr working at a primary or secondary school in six prefectures in Japan in 1992-1996 (membership, approximately 180, 000/yr). The observed number of deaths during the study period was obtained from the file of deceased members kept at the MAPST. The cause of death was determined by examining the death benefit application submitted by bereaved families. The sex-and-causespecific mortality was examined by using age-adjusted standardized mortality ratios (SMRs) in comparison with the general population, all workers, or professional and technical workers (peer group). During the study period, 719 deaths occurred. The male school personnel had a significantly lower risk of mortality from all causes than the general population [SMR: 0.45, 95% confidence interval (95%Cl)=0.41-0.49], all workers (SMR: 0.61, 95%CI=0.56-0.67), and the peer group (SMR: 0.70, 95%Cl=0.64-0.77). The female school personnel had a significantly lower risk of mortality from all causes than the general population (SMR: 0.46, 95%CI=0.40-0.53), and all workers (SMR: 0.81, 95%CI=0.71-0.93), but the difference from the peer group was not statistically significant (SMR: 0.93, 95%CI=0.82-1.07). Lower mortality in school personnel compared with the three populations was observed from all cancers (SMR: male, 0.54-0.68; female, 0.54-0.93), heart diseases (SMR: male, 0.600.94; female, 0.30-0.90), cerebrovascular diseases (SMR: male, 0.33-0.50; female, 0.31-0.61), and suicide (SMR: male, 0.36-0.68; female, 0.42-0.91). These findings indicate that Japanese school personnel working at a primary or secondary school had only half the mortality of the general population in both sexes. The causes of the low mortality among school personnel, including lifestyle factors and work environment, need to be studied to develop health promotion activities for other occupational employees in Japan.
