Youth physical activity resource use and activity measured by accelerometry.

OBJECTIVES To examine whether use of physical activity resources (eg, parks) was associated with daily physical activity measured by accelerometry. METHODS One hundred eleven adolescents completed a travel diary with concurrent accelerometry. The main exposure was self-reported use of a physical activity resource (none /1+ resources). The main outcomes were total minutes spent in daily (1) moderate-vigorous physical activity and (2) vigorous physical activity. RESULTS Using a physical activity resource was significantly associated with total minutes in moderate-vigorous physical activity. African Americans and males had significantly greater moderate-vigorous physical activity. CONCLUSIONS Results from this study support the development and use of physical activity resources.
