Contextualizing the “Student Body”: Is Exposure to Older Students Associated With Body Dissatisfaction in Female Early Adolescents?

Research on teens’ body dissatisfaction documents the role of proximal social influences (e.g., peers and family) and distal social influences (e.g., mass media) but largely ignores intermediate contextual factors such as school environment. Is there a link between individual body image and student body? We assessed drive for thinness, body dissatisfaction, thin-ideal internalization, and body objectification in an ethnically diverse sample of 1,536 female students educated in U.S. school districts varying in the degree to which younger students (fifth and sixth graders) are educated alongside older students (seventh and eighth graders). We studied three different grade groupings: junior high (Grades K–6 housed together/Grades 7–8 housed together), middle school (K–5/6–8), and extended middle school (K–4/5–8). As predicted, fifth and sixth graders attending schools with older students reported more negative body experiences than their age peers attending schools with younger students; similar effects were...
