IntroductionSleep, sedentary behavior, and physical activity (PA) are modifiable targets for reducing cardiometabolic risk, yet the interplay between these factors is not well understood. Previous research has primarily examined the role of increasing PA in improving sleep duration and quality and has focused on pediatric populations.HypothesisWe hypothesized that sufficient and restful sleep, absence of insomnia symptoms, and limited naps would be associated with lower sedentary time, higher duration of light and moderate-to-vigorous intensity PA (LIPA, MVPA) and greater odds of meeting US physical activity guidelines (PAGs) in diverse Hispanic/Latino adults.MethodsBaseline data on 12,750 adults, aged 18-74y, from the Hispanic Community Health Study/Study of Latinos were examined. Sleep phenotypes were self-reported. Sedentary, LIPA, and MVPA time (min/d) were objectively measured for 7 days using an accelerometer. Multivariable linear and logistic regression models were used to estimate overall cross-sectional associations and by sex and body mass index category. Models accounted for sample weights and design effects and were adjusted for socio-demographic and medical covariates.ResultsEach additional hour of sleep was associated with lower LIPA (β=-4.20, p
