BACKGROUND: HIV infection disproportionately impacts minorities; yet research on racial/ethnic differences in the prevalence and correlates of HIV risk behaviors is limited. OBJECTIVE: This study examined racial/ethnic differences in the rates of HIV risk behaviors and whether the relationship between HIV risk factors and HIV risk behaviors varies by race/ethnicity in clients participating in NIDA Clinical Trials Network trials. RESULTS: The sample was 41% non-Hispanic White, 32% non-Hispanic Black, and 27% Hispanic (N = 2,063). HIV risk behaviors and measures of substance and psychosocial HIV risk factors in the past month were obtained. Non-Hispanic Blacks engaged in less HIV sexual risk behaviors overall than non-Hispanic Whites. While non-Hispanic Whites were the most likely to report any injection drug use, Hispanics engaged in the most HIV drug risk behaviors. Specific risk factors were differentially predictive of HIV risk behavior by race/ethnicity. Alcohol use severity was related to engaging in higher sex risk behaviors for non-Hispanic Blacks and Whites. Greater psychiatric severity was related to engaging in higher sex risk behaviors for non-Hispanic Whites. Drug use severity was associated with engaging in higher risk drug behaviors for non-Hispanic Whites and Hispanics with the magnitude of the relationship stronger for Hispanics. CONCLUSIONS: These findings highlight the need for further research testing HIV risk prevention interventions within racial/ethnic groups to identify target behaviors or risk factors that are salient to inform HIV interventions. SCIENTIFIC SIGNIFICANCE: The present study provides a systematic examination of race/ethnicity differences in the relationship between psychosocial risk factors and HIV risk behaviors.
