Study Summary
The prevalence of overweight among adolescents (BMI-for-age %tile over the 95th percentile) has more than tripled over the past 3 decades in the US. Overweight and physical inactivity disproportionately affect low- income, female, African American adolescents. A prior health-promotion/ obesity-prevention program for adolescents developed and tested by our group (Challenge!) showed that adolescents who received the intervention were less likely to become overweight or obese over 2 years when compared to the control group. This intervention was administered one-on-one to adolescents in their homes or community by a college-aged mentor. Schools are an ideal setting for interventions because the effect can be far-reaching and sustainable. School-based obesity-prevention interventions have thus far shown modest results. The purpose of this study is to evaluate the impact of a multilevel intervention that includes both the Challenge program administered in a small group format after school using mentors and teachers and a school-wide environmental change on adolescent females' body composition, diet, and physical activity. The intervention is targeted to 6th and 7th grade female students. The small group intervention is conducted over 12 weeks and includes goal setting focusing on healthy diet and physical activity, along with membership and weekly trips to the YMCA. The environmental intervention includes a Health and Activity Committee (HAC), comprised of 8th grade female students (popular opinion leaders), school personnel, parents, and community members. The HAC develops school-wide health promotion messages and activities. Parents of participating 6th and 7th grade girls provide information on family variables. The hypotheses are that females who receive the small group or environmental intervention are at less risk of weight gain (overweight) than females in the control small group condition, that females in environmental schools are at less risk of weight gain (
