Exploring the intersection of neighborhood racial and economic composition and individual race on substance use among male adolescents

This article examines how Blacks and Whites living in neighborhoods with divergent racial and income profiles differed in early onset (by age 14 years) and adolescent lifetime prevalence (by age 18 years) of substance use, with longitudinal data from 473 high-risk boys (58% Black). A latent profile analysis identified four neighborhood classes: Black, lower-income; racially mixed, middle-income; White, middle-income; and White, upper-income. Bivariate analyses showed that Blacks living in racially mixed, middle-income neighborhoods reported the lowest rates of tobacco and marijuana use. Whites living in White, upper-income neighborhoods reported higher substance use prevalence, particularly marijuana. Findings suggest that substance use prevention efforts are critical for Whites in upper-income communities.
