摘要

Gay, bisexual, and other men who have sex with men (MSM) are disproportionately affected by HIV infection in the United States, especially Black MSM (BMSM) and Hispanic/Latino MSM (HLMSM). Long-acting preexposure prophylaxis (LA PrEP) is effective in preventing HIV; however, medical mistrust may contribute to barriers in uptake among BMSM and HLMSM. We assessed the role of medical mistrust in BMSM and HLMSM’s unwillingness to use LA PrEP. BMSM and HLMSM aged ≥18 years without a previous HIV diagnosis or current PrEP use were recruited through dating and general interest websites/apps. Using Poisson regression with robust standard errors, we conducted multivariate analyses to assess the association between medical mistrust and willingness to use LA PrEP (i.e., injection or rod implanted in the arm) separately for each racial/ethnic group. Over 90% of the 1,126 BMSM and 924 HLMSM in this study were willing to use some form of PrEP; however, only 74% of BMSM and 81% of HLMSM were willing to use PrEP injections, and significantly fewer BMSM (30%) were willing to receive a PrEP implant compared with 44% of HLMSM. After controlling for sociodemographic, behavioral, and clinical covariates, medical mistrust was associated with lower willingness to use LA PrEP for BMSM, but not for HLMSM. Addressing and reducing medical mistrust among BMSM is important to increase the use of LA PrEP as an effective HIV prevention strategy. Addressing structural barriers and building trust within healthcare systems are crucial steps in reducing disparities in HIV infection among BMSM and HLMSM.
