This study found a significant association between sleep duration and symptoms of depression in the Korean population. Individuals who slept less than 6 hours or more than 9 hours were more likely to experience symptoms of depression compared to those who slept 6-8 hours.
This study aimed to determine the association between symptoms of depression and sleep duration in a representative sample of the Korean population. Using national cross-sectional data from the seventh Korea National Health and Nutrition Examination Surveys (KNHANES-VII), 5461 adults aged 18-49 years were analyzed using logistic regression models. The proportions of participants with total daily sleep durations (24 h) of <6 h, 6-8 h, and >= 9 h were 26.2%, 60.6%, and 13.3%, respectively. The proportions of individuals with symptoms of depression in the <6 h, 6-8 h, and >= 9 h sleep duration groups were 37.4%, 46.3%, and 16.3%, respectively. The odds ratios (ORs) were significantly higher in the <6 h and >= 9 h sleep groups than in the 6-8 h sleep group. There was a significant association between short (<6 h/day) and long (>= 9 h/day) sleep duration and symptoms of depression among the general Korean population. In particular, our findings suggest that short sleep (<6 h/day) is more associated with symptoms of depression than long sleep (>= 9 h/day).
