Objective:We investigated the association between suicide and pesticide exposure in a community-based cohort study.Methods:We performed a longitudinal analysis of 6333 who participated in the initial survey of the Korean Genome and Epidemiology Study. Data were collected using a questionnaire to assess the prevalence of suicide. We calculated the hazard ratios (HRs) for suicide by pesticide exposure using the Cox proportional hazard model.Results:After adjusting for variables, participants exposed to pesticides had a 1.88-fold increased risk of suicide (HR, 1.88; 95% confidence interval [CI], 1.11 to 3.16) than those who were not exposed. Study populations with greater pesticide use (HR, 2.42; 95% CI, 1.27 to 4.60) and pesticide addiction had the highest suicide rates (HR, 1.91; 95% CI, 1.03 to 3.56).Conclusions:Pesticide exposure for suicide should be considered during the development and implementation of suicide prevention in rural area.
