Only 12 percent of U.S. adolescents get the recommended amount of moderate physical activity each day—60 minutes. Modifying the built environment where children live, play, and attend school may increase physical activity levels.
This study looked at the association between the outdoor built environment and moderate-to-vigorous-physical activity (MVPA) in girls. (Adolescent females are known to be less physically active than their male counterparts.) The researchers hypothesized that the presence of parks, physical activity facilities, and higher population density would be positively associated with higher physical activity levels.
Study participants were teenage girls in San Diego and Minneapolis who had previously been part of the Trial of Activity for Adolescent Girls. Activity levels were measured over six days using global positioning systems (GPS) and accelerometers.
Key Findings:
Understanding where physical activity does and does not occur can inform policies that encourage physical activity and reduce sedentary behaviors.
