The Effects of Middle School Weight Climate on Youth With Higher Body Weight

This study examines whether social-emotional difficulties associated with higher body weight vary across schools as a function of the school's weight climate. Weight climate, characterized by weight-policing, was assessed indirectly by examining how strongly self-reported weight predicts victim reputation within 26 ethnically diverse middle schools. Social-emotional indicators included self-reported loneliness, school belonging, and self-esteem. In schools with stronger weight-policing at seventh grade, loneliness was intensified by eighth grade among both girls (n = 2,101) and boys (n = 1,985) with higher weight. Similar effects were found for low self-esteem among girls. Additionally, boys-regardless of their weight-reported lower sense of belonging in schools with stronger weight-policing. The study offers a new method to estimate school weight climate, and the findings provide insights for interventions.
