This study sought to assess working hour per week among doctors in training and to examine its association with depressive symptoms, using a cross-sectional survey of 1,661 interns and residents from the 2014 Korean Interns & Residents Survey. Working hours per week was classified into five categories (i.e. less than 60 hours, 60-79 hours, 80-99 hours, 100-119 hours, and 120-168 hours). Depressive symptoms during the previous week were measured by using CES-D 10. We found that 86%(N=1,429) of interns and residents worked 60 hours or more per week. Compared to the "less than 60 hours" group, long working hours for interns and residents were significantly associated with depressive symptoms: "60-79 hours"(PR: 1.56, 95% CI: 1.05, 2.32), "80-99 hours"(PR: 2.27, 95% CI: 1.54, 3.33), "100-119 hours"(PR: 2.62, 95% CI: 1.76, 3.89), and "120-168 hours"(PR: 3.28, 95% CI: 2.21, 4.86) after adjusting for confounders including medical specialty and training year.
