Comparison of sickness absences across industries: A cross-sectional study using the JILPT Data Archive

The three industries with a high incidence of mental health leave had a high percentage of professional/technical workers and a common background of heavy workloads. In addition, role ambiguity, particularly in the education and medical industries, could lead to stress. The association between the transportation/postal industry and sickness absences due to lifestyle-related diseases and heart disease was probably influenced by work style and lifestyle, whereas the association between the medical care/welfare industry and sickness absences due to cancer was probably influenced by the high percentage of women in this industry. This study could not be adjusted for several variables examined in other studies, such as sex, and caution should be exercised when interpreting the results, especially regarding absences due to cancer.
