Eating disorder symptoms among undergraduate and graduate students at 12 U.S. colleges and universities.

OBJECTIVES: We sought to estimate the prevalence of eating disorder symptoms in a large sample of U.S. college students and variations therein across student characteristics.

METHODS: Participants were 9713 students from 12 colleges and universities participating in the Healthy Bodies Study. We used gender-stratified logistic regression to estimate bivariate correlates of elevated eating disorder symptoms, past-month objective binge eating, and past-month compensatory behaviors across student characteristics including age, degree-level, sexual orientation, race/ethnicity, first-generation status, citizenship, academic and extracurricular characteristics, and weight status. Eating disorder outcomes were based on the Eating Disorder Examination Questionnaire.

RESULTS: We observed higher prevalence of objective binge eating among females relative to males (49% versus 30%, p<0.001), but similar prevalence of compensatory behaviors (31% versus 29%). Weight status was the most consistent predictor of eating disorder risk with significantly more symptoms seen among individuals with overweight and obesity. When compared to individuals with a healthy weight, those with overweight had greater eating disorder risk (males OR=3.5; females OR=2.0), binge eating (males OR=2.1; females OR=1.9), and use of compensatory behaviors (males OR=1.5; females OR=1.3).

CONCLUSIONS: This study suggests smaller gender difference in prevalence of eating disorder symptoms than previously reported and identifies students with overweight/obesity as salient targets for campus-based eating disorder screening and early intervention efforts.
