| Research Abstract |
The authors investigated the effect of shift work on the risk of obesity and prostate cancer in the retrospective cohort study, which was established on a health-care database from a Japanese manufacturing corporation. Kaplan-Meier survival analysis visually demonstrated significant risk of obesity among shift workers. The risk became apparent after 10 years of follow-up(RR=1.14, 95%CI : 1.01, 1.28). Non-significant increase in risk of prostate cancer was also observed among shift workers (RR=1.79, 95%CI : 0.57, 5.68).
