Abstract

HIV-related stigma is a major challenge to HIV prevention for sexual minority men (SMM) in Zambia, but little is known about the underlying mechanisms. This study aimed to investigate whether physician-patient interaction quality mediates the relationship between HIV-related stigma and HIV-prevention behaviors among SMM. Data were collected using a cross-sectional survey from 194 SMM (aged: mean=24.08, SD=4.27) across four districts in Zambia between February and November 2021. Participants were asked about their demographic characteristics, HIV-related stigma, SMM-related stigma, physician-patient interaction quality, HIV-testing intention, and use of pre-exposure prophylaxis (PrEP). Path analysis was used to test the mediation effect of physician-patient interaction quality in the associations of HIV-related stigma/SMM-related stigma with HIV-testing intention and current PrEP use. Higher self-reported physician-patient interaction quality was negatively associated with HIV-related stigma (β=- 0.444, z=- 2.223, p < 0.05), and positively associated with HIV-testing intention (β=0.039, z=5.121, p < 0.001) and current PrEP use (β=0.008, z=2.723, p < 0.01). HIV-related stigma among SMM had a significant and negative indirect effect on HIV-testing intention (β=- 0.017, z = - 2.006, p < 0.05), and current PrEP use (β=- 0.004, z=- 2.009, p < 0.05) through physician-patient interaction quality. Contrary to our expectations, SMM-related stigma did not have a significant and negative indirect effect on HIV prevention behaviors through physician-patient interaction quality. Health interventions need to improve physician-patient interaction quality by offering healthcare provider training, targeting HIV-related stigma in healthcare settings, and devising inclusive healthcare policies to promote HIV prevention efforts.
