Association between Sleep Duration and Prevalence of Dyslipidemia in Korean Adults: The Sixth Korean National Health and Nutrition Examination Survey

ABSTRACT

BACKGROUND: This study was performed to evaluate the correlation between sleep duration and the prevalence of dyslipidemia in Korean adults.METHODS: Among the 18,034 adults who participated in the 6th Korean National Health and Nutrition Examination Survey, 3,020 adults with missing values were excluded, and 15,014 adults were enrolled in our study. The association between sleep duration and the prevalence of dyslipidemia was analyzed by multiple logistic regression. We controlled for factors including sex, age, body mass index, smoking, drinking, diabetes mellitus, hypertension, walking exercise, muscular exercise, and stress.RESULTS: After adjusting for sex, age, body mass index, smoking, drinking, diabetes mellitus, hypertension, walking, muscular exercise, and stress in a multiple logistic regression analysis, sleep duration was associated with the prevalence of dyslipidemia. The group who slept for less than 7 hours per night had a higher prevalence of dyslipidemia than the group who slept for between 7 and 9 hours per night.CONCLUSION: In this study, a shorter sleep duration was associated with a higher prevalence of dyslipidemia.
