School climate-related determinants of physical activity among high school girls and boys.

Introduction: In the United States, physical activity (PA) among adolescents is declining; 75% of high school students do not meet daily PA guidelines. Low rates of PA are more prevalent among high school girls. Schools provide an optimal environment to target and promote PA. However, school climate has not yet been studied for its importance in promoting PA among high school students, particularly girls.

Methods: A cross-sectional analysis was conducted using the Georgia Student Health Survey (GSHS) 2.0 data on perceptions of different school climate measures and self-reported weekly PA levels to study gender differences in the association of PA with school climate.

Results: Data from a total of 362,926 students (48% males and 52% females) were analyzed. For both genders, the odds of being physically active increased with a more positive report of supportive school environments, school connectedness, peer social support, school physical environments, cultural acceptance, school safety, and adult social support. Peer victimization was associated with increased odds of PA among females but lower odds for males.

Conclusion: Results suggest that improving school climate can increase PA among adolescents. As new or existing school-based interventions and policies are considered by states and local governments, improving the school climate should be part of the overall strategy. Future research is needed on peer victimization among physically active females.

Implications And Contributions: This study evaluated gender differences in the association between measures of school climate and PA among high school students. School climate or policies fostering positive environments including feelings of safety, connectedness, and peer support may increase adolescent PA; addressing peer victimization and fights may reduce gender disparities in PA.
