Reducing risk factors for childhood obesity: the Tommie Smith Youth Athletic Initiative.

This study has sought to determine if the Tommie Smith Youth Athletic Initiative (TSYAI) intervention could decrease the risk factors for childhood obesity among children 5 to 10 years of age. The TSYAI intervention is a 14-week after-school intervention for students in Grades K-5 that was started during the spring of 2008. It serves 63 children in a predominantly African American elementary school. The intervention consists of supervised after-school sessions 3 days per week. These sessions include 2 days of physical activity (flexibility, resistance, and track-and-field training) and 1 day of 45 min of nutrition education modules based on the Transtheoretical Model of behavior change followed by 45 min of group physical activity. Ninety-two percent of the participants are African American and 60% are overweight or obese (>85th percentile BMI for age and gender). The findings indicate that the TSYAI intervention significantly improves the participant's cardiovascular fitness, body composition, and dietary habits.
