Sleep Duration in Adolescent Girls: Correlates and Association with Obesity Risk
(2013) Moshkovich, Olga; Saksvig, Brit I; Epidemiology and Biostatistics; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
The present study aimed to identify demographic, behavioral, and school-related factors associated with week night sleep duration among an ethnically diverse sample of 582 adolescent girls from the Trial of Activity for Adolescent Girls (TAAG) 2. The distribution of sleep duration categories (<7 hours, 7-9 hours, and >9 hours) differed significantly among ethnic groups in bivariate analyses, but not in the final multivariate model. Additionally, sleep duration was negatively associated with distance to school from home, typical time spent on the computer, and school start time. In contrast to previous findings, shortened sleep duration was not associated with increased body mass index (BMI), body fat percentage, or quantity of moderate-to-vigorous physical activity (MVPA). Findings show support for delayed school start times. In addition, future research should examine whether interventions to reduce screen time activities among adolescents is effective in increasing their sleep duration.
