Factors correlated with pre-exposure prophylaxis (PrEP) awareness and use among black adults in the United States: implications for improving HIV prevention

HIV remains a significant public health concern for Black adults (BA) in the United States. Pre-exposure prophylaxis (PrEP) is a highly effective prevention tool prescribed to protect the health of HIV-uninfected individuals. Yet, low rates of PrEP awareness and utilization persist among BA. Less is understood about the pathways that may promote PrEP uptake. The present study explored factors associated with PrEP awareness and use among BA. Using a cross-sectional sample of 666 BA, we employed multivariable logistic regression models to examine the relationship between PrEP and several covariates. Most participants were unaware of PrEP (71%). Reporting history of incarceration and lifetime sexually transmitted infection testing [aOR 1.76 (1.19, 2.59), p < 0.05] had greater odds of PrEP awareness. Only 6% of respondents had ever taken PrEP. Reports of incarceration history [aOR 9.96 (2.82, 35.14), p < 0.05], concurrent sexual partners [aOR 1.09 (1.00, 1.18), p < 0.05], and substance use during sex [aOR 4.23 (1.02, 17.48), p < 0.05] had greater odds of PrEP use. Interventions aiming to improve PrEP uptake among BA must consider the individual, social, and structural contexts associated with its awareness and use. Enhanced efforts by healthcare providers and institutions may better facilitate access to PrEP for HIV prevention and control transmission.
