Latino Sexual Minority Men's Pre-Exposure Prophylaxis Modality Preferences: A Latent Class Analysis

Pre-exposure prophylaxis (PrEP) is an effective HIV prevention tool available in several modalities (e.g., daily oral, injectable, implants, rectal douching). The Ending the HIV Epidemic (EHE) initiative, a national initiative that began in 2019 as a partnership among the Department of Health and Human Services and other federal agencies (e.g., the Centers for Disease Control and Prevention, National Institute of Health), seeks to increase PrEP engagement for groups experiencing HIV inequities, including Latino sexual minority men (LSMM). Given the limited research on PrEP modality preferences among LSMM, this study aimed to explore and characterize these preferences. LSMM (n = 214) not using PrEP and living in South Florida participated in the DÍMELO study, which examined PrEP engagement among LSMM in South Florida. Authors employed latent class analysis (LCA) to identify groups of LSMM based on their PrEP modality preferences and examined predictors of class membership. LCA results led to a three-class solution with participants who were: (1) reluctant to use most PrEP modalities (30.5%), (2) PrEP willing, with constraints (36.0%), and (3) enthusiastically accepting of all PrEP modalities (33.5%). LSMM in the reluctant class (Class 1) showed minimal interest in most PrEP modalities. The constrained class (Class 2) displayed interest in daily oral, on-demand, and quarterly injectable PrEP while the enthusiastic class (Class 3) demonstrated high interest in all modalities except rectal douching. Key predictors of PrEP modality preferences were altruism, community normalization of PrEP, and migration history. Understanding LSMM's PrEP modality preferences can enhance the reach of PrEP to LSMM, a group the EHE initiative prioritizes. The current findings suggest the need to tailor PrEP outreach efforts to promote various PrEP modalities based on LSMM's preferences.
