dc.description.abstract | BackgroundIncreasing evidence suggests that sleep duration is associated with risks of various diseases including type 2 diabetes, cardiovascular disease (CVD), and certain types of cancer. However, the relationship with mortality is not clear, particularly in non-European populations. In this study, we investigated the association between sleep duration and mortality in a population-based prospective cohort of Korean adults.MethodsThis analysis included 34,264 participants (14,704 men and 19,560 women) of the Korea National Health and Nutrition Examination Survey (KNHANES) 2007-2013 who agreed to mortality follow-up through December 31, 2016. Sleep duration was self-reported at baseline and was categorized into four groups: <= 4, 5-6, 7-8, and >= 9h/day. Cox proportional hazards models were performed to estimate hazard ratios (HR) and 95% confidence intervals (CI) for the associations with mortality (all-cause as well as CVD- and cancer-specific), adjusting for potential confounders.ResultsDuring up to 9.5years of follow-up, we identified a total of 1028 deaths. We observed the lowest mortality at 5-6h/day sleep. Compared with 7-8h/day of sleep, short (<= 4h/day) and long (>= 9h/day) sleep were associated with a 1.05-fold (95% CI=0.79-1.39) and 1.47-fold (95% CI=1.15-1.87) higher all-cause mortality, respectively. After additional adjustment for self-rated health, the positive association with short sleep disappeared (HR=0.99, 95% CI=0.75-1.32) and the association with long sleep was slightly attenuated (HR=1.38, 95% CI=1.08-1.76). Long sleep was also nonsignificantly positively associated with both cancer-mortality (HR=1.30, 95% CI=0.86-1.98) and CVD-mortality (HR=1.27, 95% CI=0.73-2.21). There was no statistically significant evidence for nonlinearity in the relationships between sleep duration and mortality (all-cause as well as CVD- and cancer-specific). Effect modification by age, sex, education, and occupation were not statistically significant.ConclusionsOur findings suggest that long sleep duration is associated with an increased all-cause mortality in Korean adults. | - |
