The Influence of Relationship Dynamics and Sexual Agreements on Perceived Partner Support and Benefit of PrEP Use Among Same-Sex Male Couples in the U.S.

Use of Pre-exposure prophylaxis (PrEP) for HIV prevention by men who have sex with men (MSM) may be impacted by relationship dynamics. We assessed perceived partner support of PrEP use and benefit of PrEP by relationship characteristics among male couples. Baseline data from a randomized control trial of video-based HIV counseling and testing among male couples in the U.S. were used in adjusted multilevel regression models to assess individual and dyadic characteristics. Among 659 participants, 73.3% thought their partner would be supportive of their PrEP use; 26.7% reported their partner would not support PrEP use, which was significantly associated with intimate partner violence (IPV) (p = 0.008). Most (57.7%) did not believe PrEP would be beneficial to them or their partner. Couples with a sexual agreement allowing outside partners were significantly associated with higher perceived support of partners for PrEP (p < 0.001) and benefit of PrEP use (p < 0.001). Perceived partner support of PrEP was high but perceived benefit of PrEP was low, both shaped by relationship dynamics that highlight the need for tailored dyadic interventions. The association between perceived PrEP support and IPV points to the need to integrate relationship contexts in HIV prevention programs.
