A research group led by Professor Renki Kobayashi of the University of Tokyo Graduate School of Medicine investigated the mortality rate gap and cause of death by occupation in Japan over the past 30 years, and found that the mortality rate of all men is declining except for managers. I understood.While there was a large decline in clerical and civil servants, the decline in agriculture and forestry and fishing workers was small, and it became clear that the disparity between occupations was widening.
According to the University of Tokyo, researchers from the University of Tsukuba, the National Institute of Public Health, and Waseda University also participated in the research group.Using anonymized data from the Vital Statistics Survey by Occupation / Industry, the occupations of Japanese men and women aged 30 to 59 are divided into 12 such as managers, clerks, civil servants, construction workers, transportation drivers, and service workers. Classification, occupational age-adjusted mortality rates from 1980 to 2010 were calculated every 5 years.
The mortality rate by occupation for men decreased in all but managerial positions, with the decline in clerical and civil servants being particularly significant.On the other hand, the relative mortality rate was increasing among managers, agriculture and forestry workers, fishery workers, and service workers.In terms of causes of death, reduced mortality from cancer and cerebrovascular disease has reduced mortality, but suicide has widened the gap.The mortality disparity between occupations was small for females, and the disparity tended to disappear.
The research group believes that it is necessary to promote preventive measures against suicide and cancer, which are the main causes of death in occupations with high mortality rates.The research results were published in the electronic version of the international medical journal "BMJ Open".
