Eating disorder prevalence among multiracial US undergraduate and graduate students: Is multiracial risk different than the sum of each identity?

The number of individuals identifying as multiracial in the United States (US) has significantly increased in the past few decades, yet they are rarely the focus of study in eating disorders (ED) research. The current study is among the first to examine prevalence estimates of ED pathology across several distinct multiracial groups, to contrast prevalence estimates of ED pathology in each multiracial group with those among the corresponding monoracial identities, and to investigate these findings intersectionally with gender identity. Data from 145,379 US students, 11,433 of whom were multiracial, were collected from 199 US colleges and universities participating in the Healthy Minds Study between 2014 and 2019. Elevated ED pathology was defined as a score ≥ 2 on the SCOFF. Multiracial individuals identifying as American Indian/Alaskan Native and Hispanic/Latinx exhibited the highest prevalence estimates of elevated ED pathology (41.4% compared to 23.5% in the full sample). This group, as well as some other doubly marginalized groups (African American/Black and Hispanic/Latinx; African American/Black and Asian American/Asian), exhibited higher prevalence of elevated ED pathology than expected based on the observed prevalence estimates in their corresponding monoracial groups. Across gender identities, greater than expected prevalence estimates of elevated ED pathology were observed among multiracial individuals identifying as African American/Black and White and lower than expected prevalence estimates were observed among multiracial individuals identifying as Middle Eastern/Arab/Arab American and White. These results have important implications for understanding ED pathology in multiracial individuals and should inform intervention and treatment efforts to support individuals from these underserved groups.
