title: The Risk of Being Obese According to Short Sleep Duration Is Modulated after Menopause in Korean Women.
abstract: We previously reported that women with short sleep duration consumed more dietary carbohydrate and showed an increased risk for obesity compared to those who slept adequately, but not for men. Using a cross-sectional study of 17,841 Korean women, we investigated the influence of sleep duration on obesity-related variables and consumption of dietary carbohydrate-rich foods in relation to menopausal status. Premenopausal women with short sleep duration had significantly greater body weight (p= 0.007), body mass index (p= 0.003), systolic and diastolic blood pressures (p= 0.028 andp= 0.024, respectively), prevalence of obesity (p< 0.016), and consumption of more carbohydrate-rich foods such as staple foods (p= 0.026) and simple sugar-rich foods (p= 0.044) than those with adequate sleep duration after adjustment for covariates. Premenopausal women with short sleep duration were more obese by 1.171 times compared to subjects adequate sleep duration (95% confidence interval = 1.030-1.330). However, obesity-related variables, dietary consumption, and odds of being obese did not differ according to sleep duration for postmenopausal women. The findings suggest that the increased risk for obesity and consumption of dietary carbohydrate-rich foods with short sleep duration appeared to disappear after menopause in Korean women.
