N2  - We attempted to explore the relationship between working hours and sleep disturbance according to occupation and gender among Korean workers. Data were derived from the third Korean Working Conditions Survey, conducted in 2011 by the Korea Occupational Safety and Health Agency. From a total of 50 032 workers, 34 783 salaried contract workers were selected. Work hours were categorized as <40, 40-48 (reference), 49-60, and >60 h/week. The outcome variable was sleep disturbance, which was assessed by a single question item (During the past 12 months, have you experienced sleep disturbance or insomnia?). Multiple survey logistic regression models were performed after adjusting with age, education level, marital status, self-rated health, salary, shift work, smoking and alcohol drinking. Gender and occupation were stratified in these models. The adjusted odds ratio (OR) for sleep disturbance in male non-manual workers with long work hours (>60 h/week) was 3.017 [95% confidence interval (CI) 1.956-4.653]. In female non-manual workers who work 49-60 working hour per week, the OR was 1.525 (95% CI 1.034-2.249). Long working hours can be a risk factor for sleep disturbance in Korean workers. The association was especially prominent in male non-manual workers.<p />  <p>Language: en</p>
