Background: Many studies have reported noticeable increases in the proportion of employees working either relatively short or relatively long hours. Such trends have been accompanied by an increasing concern regarding work hour mismatches defined as a discrepancy between actual and preferred work hours. The aim of this study was to investigate association between work hour mismatch and depression. Methods: Data regarding work hour mismatches for 47,551 adults were extracted from the 2017 Korean Working Conditions Survey. The World Health Organization-Five Well-Being Index was used to measure depression. Multiple logistic regression analyses were performed to examine the association between work hour mismatch and depression. Results: Men and women workers with work hour mismatch were more likely to have depression [underemployed males: odds ratio (OR) = 1.30, 95% confidence interval (CI) = 1.14-1.49, overemployed males: OR = 1.28, 95% CI = 1.18-1.40; underemployed females: OR = 1.37, 95% CI = 1.20-1.56, overemployed females: OR = 1.12, 95% CI = 1.02-1.23]. Underemployed workers, workers who worked more than 52 hours per week, and workers with a high income level, all had higher ORs for depression. The greater the discrepancy between actual and preferred work hours, the higher OR for depression among both underemployed and overemployed workers. Conclusions: A difference between actual and preferred work hours was associated with depression. Underemployed workers had a higher risk of depression than that of overemployed workers. As a work hour mismatch negatively affected workers' mental health, it is important to reduce work hours mismatches as well as shorten the absolute number of work hours.

The purpose of this study is to examine the effect of subjective overwork on health and the moderating effect of risk perception in the relationship between subjective overwork and health. The data used in this study are the fourth Korean Working Condition Survey (KWCS) conducted by Korea Occupational Safety and Health Agency (KOSHA) in 2014. The items related to actual working hours, subjective overwork, health, and risk perception were used. A total of 18,508 workers who are 1) waged workers, 2) work more than three days a week, 3) work more than 21 hours a week, 4) work longer than preferred work hours or work as longer as they desired were selected. Hierarchical regression analysis was performed to identify the effect of actual work hours, subjective overwork, prevalence of risk, lethalness of accident damage on health and to determine the moderating effects of prevalence of risk and lethalness of accident damage. As a result, actual work hours, subjective overwork, prevalence of risk, lethalness of accident damage had an effect on worker's health problems. Second, lethalness of accident damage had a moderating effect in the relationship between subjective overwork and health. These results suggest that organizations should manage worker's environmental factors and other threats that could increase the lethalness of accident damage.
