Examining the Intersection of Ethnoracial Disparities and HIV Status in Substance Use Risks among U.S. Adults

Abstract

Black/African American and Hispanic Americans experience significant HIV-related disparities. Substance use might be a contributing factor to these disparities, but there is limited research on this topic. This study investigated various substance use risks by HIV status and race/ethnicity (Black, Hispanic, White) among U.S. adults. We used data from the 2005–2019 National Survey on Drug Use and Health (N = 541,921). In each racial/ethnic group, the prevalence rates of past-year and past-month tobacco, alcohol, cannabis, and cocaine use, and past-year alcohol and illicit drug use disorders were estimated by HIV status. A series of logistic regressions with the interaction term of HIV x race/ethnicity were performed to examine race/ethnicity’s moderating effect on the HIV-substance use associations, while controlling for sociodemographic factors and survey year. Moderation analysis showed that HIV status’s association with the risks of past-year tobacco use (AOR = 1.67, 95% CI = 1.01–2.75), past-year cocaine use (AOR = 3.80, 95% CI = 1.91–7.57), past-month cocaine use (AOR = 5.34, 95% CI = 2.10–13.60), and past-year alcohol use disorder (AOR = 2.52, 95% CI = 1.29–4.92) differed significantly between Black and White adults. Between the Hispanic and White groups, HIV status’s association with the risks of past-year alcohol use (AOR = 2.00, 95% CI = 1.09–3.69), past-year cocaine use (AOR = 2.40, 95% CI = 1.06–5.39), and past-month cocaine use (AOR = 3.69, 95% CI = 1.36–10.02) also differed significantly. It is well-established that individuals with HIV face an elevated risk of substance use. Our study added valuable insights by highlighting that this phenomenon is particularly more significant among Black and Hispanic adults for several substances when compared to White adults. Implications for practice are discussed.
