Mayor's fitness council student ambassador program—evaluating a school-based obesity prevention initiative, san antonio, Texas, 2012-2013

Childhood obesity is a serious public health problem facing San Antonio, Texas, with 2010 Youth Risk Behavior Survey data showing that approximately 33% of adolescents are overweight or obese. Schools can play a critical role in improving healthy eating and physical activity through obesity prevention programs targeting students, families, and community members. The purpose of the Student Ambassador Program is to allow students the opportunity to represent the Mayor's Fitness Council, an obesity prevention initiative, by promoting healthy living at their schools and in their communities. Thirty-five Student Ambassadors in grades 5 to 12 were selected from schools across San Antonio. Through the Student Ambassador Program, students are trained on physical activity, nutrition, advocacy, and leadership. Students complete a needs assessment of their schools and communities to inform the development of a project to improve nutrition and physical activity. In spring 2013, the first cohort of Student Ambassadors will complete their school-based obesity prevention projects. Evaluation data will be presented on Student Ambassadors' physical activity and nutrition behaviors, participation in community physical activity opportunities, and youth leadership. Baseline data indicates that 40% of Student Ambassadors eat 5 or more servings of fruits and vegetables per day and 25% are physically active for 60 minutes or more per day. Evaluation data will be presented on the reach and impact of Student Ambassadors' projects on students, families, and community members. Youth-led obesity prevention initiatives, such as the Student Ambassador Program, can promote physical activity and healthy eating at schools and in communities.
