ABSTRACT

This study aimed to measure the pooled estimate of willingness to use HIV pre-exposure prophylaxis (PrEP) (WTUP) among PrEP-naïve United States (U.S.)-based men who have sex with men (MSM). PubMed, Embase, Web of Science, CINAHL, and PsycINFO were searched. The search strategy contained the keyword willingness and interest and the MeSH terms for HIV and PrEP. Articles were included if they were published between January 2005 and May 2022, reported quantitative data on WTUP among PrEP-naïve US-based MSM, and were available as full text in English. Meta-analysis was conducted to assess the pooled effect size of WTUP prevalence using a random-effects model, heterogeneity in the pooled estimate was assessed, and subgroup analyzes were conducted. Fifteen studies were included based on the inclusion and exclusion criteria. Meta-analysis revealed a pooled prevalence proportion for WTUP of 0.58 (95% CI 0.54–0.61) (or 58 out of 100) among PrEP-naïve MSM. High inter-study heterogeneity (Q = 548.10, df = 19, p < 0.01, I2 = 96.53, τ2 = 0.09) was observed. Age of the study sample and region where the data were collected significantly moderated the pooled WTUP estimate. Age-appropriate PrEP related messaging and a focus on HIV priority areas of the U.S. would be important strategies to improve WTUP among MSM in the U.S. moving forward.
