Role models and social supports related to adolescent physical activity and overweight/obesity.

Positive role models, social and community activities, and school support are protective social factors that promote youth health and well-being. Latino, African-American, Asian, multi-racial, and low-income adolescents are less likely to experience these protective social factors compared to other groups, which may contribute to health disparities. Adolescents who identify a role model, volunteer, participate in organizations outside of school, or experience high levels of teacher or other adult support at school engage in greater physical activity and are more likely to have a healthy weight. Strategies to increase these protective social factors among adolescents could help promote healthy weight and healthy behaviors.
