Associations between health indicators and sleep duration of American adults: NHANES 2011–16

Abstract

Abstract Background This study aimed to investigate associations between health indicators and sleep duration in the general population. Methods This cross-sectional data from the National Health and Nutrition Examination Survey. Self-reported sleep duration was classified into short sleep (<7 h/day), regular sleep (7–8 h/day) and long sleep duration (>8 h/day). Health indicators included lifestyle indicators (smoking, alcohol use and physical inactivity), general health indicators (waist circumference and self-reported health condition) and chronic conditions [overweight/obesity, hypertension, diabetes, high cholesterol, chronic low back pain (CLBP) and oral health problems]. A series of multinomial logistic regression analysis were performed, controlling for confounders (age, sex, marital status, ethnic background, education level and poverty-to-income ratio). Results Data of 12 835 participants were analyzed. The mean (SD) age of participants was 50.0 (±17.4) years, and 50.6% were women. After adjusting for all health indicators, current smoking (OR: 1.37; 95% CI: 1.17–1.61), a poor (OR: 1.52; 95% CI: 1.23–1.88) health condition, CLBP (OR: 1.40; 95% CI: 1.16–1.69) and oral health problems (OR: 1.28; 95% CI: 1.10–1.49) were associated with short sleep duration. No independent association with long sleep duration was observed in this study. Conclusions The results confirm that lifestyle indicators (current smoking and physical inactivity), general health indicators (self-reported health condition) and presence of some chronic conditions (CLBP and oral health problems) are associated with short sleep duration. The results did not confirm that any health indicator was associated with long sleep duration.
