TRACK 2 continues the work in the cohort established in the TRACK project which examined the factors that explain the changes in objectively-measured physical activity as children transition from elementary to middle school. TRACK 2 is following the cohort into high school and is currently measuring participants again as 9th and 11th graders.
A major goal of TRACK 2 is to inform future interventions to increase physical activity in youth by identify factors that explain changes in physical activity behavior among children transition from elementary school through middle school and into high school. A second goal is to expend the body of knowledge regarding the relationship between physical activity and other important health indicators, such as body fatness, during childhood and adolescence.
The following specific aims are currently being addressed:
- Aim 1 – To identify personal, social environmental and physical environmental factors that influence the age-related trajectory for physical activity in youth as they transition from elementary school to high school.
- Aim 2 – To describe the longitudinal associations among physical activity, sedentary behavior and measures of body weight status in youth as they transition from elementary school to high school.
- Aim 3 – To describe the relationship between physical activity, observed longitudinally during childhood and adolescence, and selected health indicators in high school students.
