(P02-043-25) Weight Bias Internalization, Weight Controllability Beliefs, and Probable Eating Disorder Associations Among Medical Students at a Private University

Objectives: To explore the association between weight bias measures with screening positive for probable eating disorders amongst medical students at a private university in Boston, Massachusetts.

Methods: Medical students (n=378) completed a web-based survey assessing weight bias internalization (Modified Weight Bias Internalization Scale [WBIS-M]), beliefs about weight controllability (Beliefs About Obese Persons [BAOP]) scale, and probable eating disorder symptoms (SCOFF questionnaire). Multivariable logistic models were used to examine the cross-sectional associations between weight bias measures and a positive probable eating disorder screening (SCOFF >2).

Results: Compared to men, women had higher weight bias internalization (WBIS-M: 3.13 vs. 2.81) and stronger beliefs that weight is within the control of higher-weight people (BAOP: 25.76 vs. 27.21; Ps < 0.05). Higher weight bias internalization was associated with higher odds of a positive probable eating disorder screening (OR: 3.46; 95% CI: 2.51-4.92).

Conclusions: Medical students with higher weight bias internalization are more vulnerable to probable eating disorders. Integration of effective interventions targeting weight bias internalization during medical education are warranted.
