Overview
Brief Summary
The primary purpose of this study is to test whether rewarding physical activity with a motivational website will increase physical activity levels in middle school-aged children over six months. As a secondary outcome, the study also tests the intervention's impact on biological measures of inflammation and metabolic function in a sub-set of study participants who agree to provide blood samples.
Detailed Description
Physical activity is associated with a variety of positive health outcomes, as well as improved metabolic profiles and reduced inflammation. However, levels of moderate to vigorous physical activity (MVPA) diminish dramatically as children move into the middle school years. To address this problem, this study tests a behavioral intervention, called "Zamzee," designed to motivate middle school-aged children to increase their levels of MVPA. The Zamzee intervention consists of a 3-axis accelerometer that tracks individual physical activity rates over time and a website that displays individual physical activity rates and provides rewards for maintaining or improving physical activity rates. The primary aim of this randomized, controlled trial is to test whether middle school-aged children randomly assigned to the Zamzee intervention will show significantly greater levels of physical activity levels over six months, compared with control group participants who wear the accelerometer but have no access to the rewards website. A secondary aim is to test the intervention's impact on biological parameters that may contribute to the long-term health effects of inactivity (including C-reactive protein as a measure of inflammation, and hemoglobin-A1C as a measure of metabolic status) in a sub-set of study participants who agree to provide blood samples.

Eligibility Criteria
Inclusion Criteria
- •Middle-school-aged students aged 11 to 14
Exclusion Criteria
- •Previously participation in a Zamzee pilot study

Outcomes
Primary Outcomes
Physical activity
Time Frame: Six months
The amount and intensity of physical activity is recorded continuously every study day that participants wear their accelerometer for the duration of the six month study. The primary outcome reported will be rates of "moderate to vigorous physical activity" as defined by the CDC.
Secondary Outcomes
- Metabolic and inflammatory biomarkers(Six months)
