Abstract

BACKGROUND
This study investigates the association between sleep duration and diabetes mellitus (DM) in a large representative population-based survey in South Korea.
METHODS
The fourth (2007-2009), fifth (2010-2012), and sixth (2013) Korea National Health and Nutrition Examination Survey data sets were used. A total of 37,989 individuals were selected for the study. Chi-square tests and multivariate logistic regression analyses were used to analyze whether general characteristics, health status, and health risk behaviors were associated with DM.
RESULTS
After adjusting for confounders, the odds of DM in short sleepers (≤5 hr/day) and long sleepers (≥9 hr/day) were 1.033-times higher (95% confidence interval [CI], 0.913-1.169) and 1.334-times higher (95% CI, 1.140-1.562), respectively, compared with individuals who slept 7 hr/day. Subgroup analysis according to gender showed a U-shaped association for both genders, although it appeared stronger in men.
CONCLUSION
This study identified a U-shaped association between sleep duration and the risk for DM. Additional studies should help clarify the important information in this study.
