Longitudinal and Geographic Trends in Perceived Racial Discrimination Among Adolescents in the U.S.: The Adolescent Brain Cognitive Development (ABCD) Study.

Abstract

This study examines longitudinal and geographic trends in perceived racial discrimination among U.S. adolescents using data from the Adolescent Brain Cognitive Development (ABCD) Study. A diverse sample of 11,868 children aged 9-10 at baseline from 22 sites across the U.S. was analyzed, assessing perceived discrimination at ages 10-11, 11-12, and 13-14 using items adapted from the Perceived Discrimination Scale. Binomial logistic regression models were used to evaluate longitudinal trends and geographic variation, adjusting for demographic factors such as race/ethnicity, parental education, and income. Results show that perceived racial discrimination increased significantly from ages 10-11 to 13-14, particularly among Black and Asian adolescents. By age 13-14, nearly half of Black adolescents and over a quarter of Asian adolescents reported discrimination. Geographic analysis revealed that Black adolescents in the Western U.S. and predominantly White affluent neighborhoods had the highest odds of perceived discrimination. Higher state-level anti-Black bias was associated with lower discrimination rates among Black adolescents but higher rates for Asian adolescents. These findings highlight the evolving nature of racial discrimination during adolescence and underscore the need for targeted interventions that address racism's mental health impacts on adolescents, particularly in high-risk geographic and socio-economic contexts.
