Children's Use of the Built Environment for Physical Activity

The study aims are to develop and test the feasibility of a pediatric physical activity
intervention that incorporates personal information on use of the built environment, and test
the intervention's preliminary efficacy at increasing physical activity. The investigators
hypothesize that it will be feasible to incorporate and measure changes in empiric GIS
(geographic information system), GPS (global positioning system), and accelerometer feedback
in the office setting as demonstrated by: i) Completeness of GPS and accelerometer data
collection (primary measure of feasibility), ii) Participation rates among adolescents in the
intervention group compared to the control group, and iii) Acceptability to patients as
measured by adolescent satisfaction.
