abstract="BACKGROUND: The after-school period provides an opportune context for adolescent physical activity. This study examined how characteristics of after-school recreation environments related to adolescent physical activity. <br><br>METHODS: Participants were 889 adolescents aged 12-17 (M = 14.1, SD = 1.4) from two US regions. Adolescents reported on whether their school offered after-school supervised physical activity, access to play areas/fields, and presence of sports facilities. Outcomes were accelerometer-measured after-school physical activity, reported physical activity on school grounds during non-school hours, attainment of 60 minutes of daily physical activity excluding school physical education, and BMI-for-age z-score. Mixed regression models adjusted for study design, region, sex, age, ethnicity, vehicles/licensed drivers in household, and distance to school. <br><br>RESULTS: School environment variables were all significantly associated with self-reported physical activity on school grounds during non-school hours (p <.001) and attainment of 60 minutes of daily physical activity (p <.05). Adolescents' accelerometer-measured after-school physical activity was most strongly associated with access to supervised physical activity (p =.008). <br><br>CONCLUSIONS: Policies and programs that provide supervised after-school physical activity and access to play areas, fields, and sports facilities may help adolescents achieve daily physical activity recommendations.<p /> <p>Language: en</p>",
