Associations of sleep duration with metabolic syndrome and its components in adult Koreans: from the Health Examinees Study

The purpose of this study is to evaluate the associations of sleep duration and with metabolic syndrome and its components. A total of 72,673 participants from the Health Examinees Study were analyzed to investigate the association of sleep duration with metabolic syndrome and its components. Using the NCEP-ATP III guideline and multiple logistic regression models, odds ratios (ORs) were estimated, stratified by sex. Long-sleep duration was significantly associated with an increased OR for metabolic syndrome in women (OR 1.53, 95 % CI 1.32-1.78), but not in men (1.19, 0.98-1.46). Both short-and long-sleep duration were significantly associated with elevated triglycerides among men (short and long sleep, respectively: 1.09, 1.00-1.19; 1.26, 1.04-1.52). Women were associated with long-sleep duration and all of metabolic syndrome components, especially triglycerides (1.29, 1.11-1.50). In conclusion, long-sleep duration is significantly associated with metabolic syndrome in women. Moreover, triglycerides revealed association across sleep duration among components of metabolic syndrome.
