Racial Discrimination is Associated with Binge-Eating Disorder in Early Adolescents: A Cross-Sectional Analysis

Background Racial and ethnic discrimination are known stressors and are associated with negative psychological and physical health outcomes. Previous studies have found relationships between racial/ethnic discrimination and binge-eating disorder (BED), though they have mainly focused on adult populations. The aim of this study was to determine associations between racial/ethnic discrimination and BED in a large, national cohort study of early adolescents. We further sought to explore associations between the racial/ethnic discrimination perpetrator (students, teachers, or other adults) and BED. Methods We analyzed cross-sectional data from the Adolescent Brain Cognitive Development Study (ABCD) (N = 11,075, 2018-2020). Logistic regression analyses examined associations between self-reported racial or ethnic discrimination and binge-eating behaviors and diagnosis. Racial/ethnic discrimination measures were assessed based on the Perceived Discrimination Scale, which measures experiences of discrimination based on race/ethnicity and frequency of ethnic discrimination by teachers, adults outside of school, and students. Binge-eating behaviors and diagnosis were based on the Kiddie Schedule for Affective Disorders and Schizophrenia (KSAD-5), adjusting for age, sex, race/ethnicity, household income, parental education, and site. Results In this racially diverse sample of adolescents (N = 11,075, mean age: 11 years), 4.7% of adolescents reported racial or ethnic discrimination and 1.1% met the criteria for BED at the one-year follow-up. In the adjusted models, racial/ethnic discrimination was associated with 3 times higher odds of having BED (OR 3.31, CI 1.66-7.74); when investigating associations between the racial/ethnic discrimination perpetrator (students, teachers, or other adults) and BED, experiencing ethnic discrimination by students and adults outside school were associated with significantly increased odds of BED diagnosis (OR 1.36, CI 1.10-1.68 & OR 1.42 CI 1.06-1.90, respectively); further, increased odds of binge eating behaviors was only significantly associated with ethnic discrimination perpetuated by students (OR 1.12, CI 1.02-1.23). Conclusions Children and adolescents who have experienced racial/ethnic discrimination, particularly when discrimination was perpetuated by other students, have higher odds of having binge-eating behaviors and diagnoses. Clinicians may consider screening for racial discrimination and providing anti-racist, trauma-informed care when evaluating and treating patients for BED.
