Predictors of Anticipated PrEP Stigma among Women with Self-Reported Problematic Substance Use: Implications for Engaging Women in the PrEP Care Continuum

Pre-exposure prophylaxis (PrEP) is an effective HIV prevention method, but it has been underutilized by women. Anticipated stigma regarding use of PrEP is a contributing factor in the underutilization of this prevention strategy. The current study explored the relationships among PrEP stigma, sex risk (i.e., inconsistent condom use, condomless sex with persons of unknown serostatus, or sex in exchange for money or drugs), substance use, attitudes toward HIV testing, and medical mistrust. Participants were 106 primarily ethnic-minority women who reported recent substance use and agreed to participate in a study exploring HIV prevention attitudes. Within this sample, the majority of participants had one or more CDC-defined PrEP indications. Findings indicate that medical mistrust was associated with perceived PrEP stereotypes and HIV testing attitudes. These results provide some insight into reasons for low PrEP uptake among women at risk for HIV. Implications for HIV prevention with women are discussed.
