abstract="BACKGROUND: This study examined associations between physical activity (recreational, non-recreational) and sleep duration among a nationally representative diverse sample of U.S. adults. <br><br>METHODS: We used cross-sectional data from 9,205 National Health and Nutrition Examination Survey 2007-2012 participants aged 20-65 years who identified as White, Black, or Hispanic. Activity (i.e., recreation, occupation, and transportation activity) was categorized into quartiles. Sleep duration was categorized as short (≤6 hours/night) or normal (>6 to ≤9 hours/night). Logistic regression was used to estimate associations of activity with sleep duration. <br><br>RESULTS: Recommended levels of recreation activity and moderate levels of transportation activity were associated with normal sleep duration (Odds Ratio (OR): = 1.33, 95% Confidence Interval (CI) = 1.08, 1.65; OR= 1.28, 95% CI= 1.02, 1.62, respectively). High occupation physical activity was associated with shorter sleep duration (OR = 0.59, 95% CI = 0.49, 0.71). Differences were observed by race/ethnicity in associations of recreation and occupation activity with sleep duration. <br><br>CONCLUSIONS: White individuals who engaged in some recreation activity, relative to being inactive, had more favorable sleep duration; whereas, high levels of occupation activity were associated with worse sleep duration among White and Black individuals. Physical activity was not associated with sleep duration among Hispanics.<p /> <p>Language: en</p>",
