ABSTRACT

This study aimed to investigate the association of sleep duration and healthy eating with measure of obesity, the body mass index (BMI) and waist circumference (WC). Data from the 2013-2015 Korea National Health and Nutrition Examination Survey, a nationwide cross-sectional survey. The association of sleep duration and the Korean Healthy Eating Index (HEI) with obesity were analyzed using multiple regression. Age, sex, household income, education level, days of physical activity, self-rated health, and year were adjusted as covariates. These covariates were included in the stepwise regression analysis. We created a combined variable (HEI × sleep duration) and examined its association with obesity. South Korea (KOR) Participants 13,349 individuals aged ≥0 years. Short sleep duration (≤ and 6 h) was associated with low total HEI score, not eating breakfast, low mixed grain intake, low total fruit intake, low total vegetable intake, and inadequate energy intake, while long sleep duration was associated with low vegetable intake. High HEI score was associated with low BMI and low WC. This study shows the association between sleep duration and overweight-obesity status with considering diet intake quality. Therefore, proper sleep duration and good diet intake quality may help prevent the risk of obesity.
