Physical activity (PA) levels decline with age starting in preadolescence, with marked disparities among underserved (racial/ethnic minority, low-income) youth, particularly girls. Factors within the social and physical environments appear to influence youth PA, but few studies have investigated their potential impact on accelerometer-measured activity of underserved youth. Purpose: This study examines how multi-level factors (individual: age, sex, BMI; social: transportation support; environmental: neighborhood characteristics) interact to influence a continuum of accelerometer-measured youth activity behaviors. Methods: Participants wore an accelerometer for 7 days. PA levels were classified as sedentary (50 mg), light (50-150 mg), moderate (150-500 mg), vigorous (>500mg), and MVPA (>=150 mg). Average daily minutes spent in PA and sedentary behaviors during waking time, the prevalence of meeting MVPA guidelines, and PA volume were estimated from accelerometer data. Three-way between-groups multivariate analysis of variance examined adjusted differences between age, sex, and weight status groups across activity outcomes. Main moderation analyses explored the effects of parent-perceived neighborhood environment and child BMI percentile in the relationship between transportation support and total child PA. Results: Participants (N=68, Mage= 9.2 years) spent an average of 103 minutes/day in MVPA and 50% of participants met MVPA guidelines. Youth engaged in more overall PA (p
