Multiple marginalization, discrimination, and disordered eating among youth aged 10–11

Abstract Objective Although rates of weight discrimination are on‐par with racial, ethnic, and gender discrimination, comparatively less work has examined impacts of weight‐based discrimination in youth, including on disordered eating. Knowing whether experiences of weight‐based discrimination, including in youth with multiply‐marginalized identities, are associated with disordered eating could identify vulnerable youth and inform intervention efforts. Method Youth ( N = 11,875) ages 10–11 were recruited through the Adolescent Brain Cognitive Development (ABCD) study. Logistic regressions using cross‐sectional data examined discrimination experiences (weight, perceived sexual orientation, race/ethnicity, national origin) and disordered eating (binge‐eating, vomiting, weight‐gain fear, weight self‐worth). Models included race/ethnicity, age, sex, parental income, and degree of elevated weight. Raked poststratification weights were used. Results Rates of weight‐based discrimination (6.2%) were similar to rates of race/ethnicity (4.4%) and sexual orientation discrimination (4.5%). Weight‐based discrimination was associated with more disordered eating. Youth reporting multiple experiences of discrimination had significantly increased disordered eating compared to youth who did not report discrimination. Discussion Weight‐based discrimination is common in youth and associated with disordered eating. Youth with elevated weight are more likely to be multiply marginalized and experience disordered eating. These findings suggest discrimination, including weight‐based discrimination, is a critical intervention target to prevent and treat eating disorders. Public Significance Experiences of discrimination contribute to poorer health; however, weight‐based discrimination is relatively understudied. Data from a large sample of youth ages 10–11 showed that youth with elevated weight reported experiencing multiple types of discrimination, and multiply‐marginalized youth had increased odds of disordered eating with each additional type of discrimination. Together, this suggests that weight‐based discrimination is a critical target to prevent and treat eating disorders, especially in multiply‐marginalized youth.
