Objectives: The increasing rates of physical inactivity and sedentary behaviors among youth are a significant public health concern. The greatest disparities in physical activity (PA) are experienced by underserved (racial/ethnic minority, low-income) youth. This study aimed to characterize accelerometer-measured PA behaviors in a sample of low-income, predominantly Latino, preadolescents. Methods: Participants wore wrist worn GENEActiv accelerometers for 7 days. PA levels were classified as sedentary (< 50 mg), light (50-150 mg), moderate (> 150-500 mg), vigorous (> 500 mg), and MVPA (≥ 150 mg). Time spent in PA levels and sedentary time (ST), prevalence of meeting MVPA guidelines, and PA volume were estimated from accelerometer data. Three-way …
