Pre-exposure prophylaxis (PrEP) is an effective tool to prevent HIV and has recently been approved in Taiwan. However, more research regarding PrEP acceptability and effective PrEP implementation is needed in Taiwan. Little is known about the intention to use PrEP and salient psychosocial factors among men who have sex with men (MSM). The purpose of this study was to examine health beliefs linked to PrEP use intention among young MSM (YMSM) in Taiwan. Using the Health Belief Model (HBM) as a guiding framework, an anonymous online survey was used to collect data from participants who were recruited using multiple channels to ensure diversity. Multivariate logistic regression was performed to examine the health beliefs linked to high PrEP use intention. Data from 1329 HIV-negative YMSM were analyzed; 488 (36.7%) were classified as having high PrEP use intention, which was found to be associated with having high perceived susceptibility to HIV infection [adjusted odds ratio (AOR) = 2.11], high perceived benefits of PrEP use (AOR = 2.14), high self-efficacy in PrEP use (AOR = 4.19), and many cues to action concerning PrEP use (AOR = 1.49). YMSM with high perceived barriers to PrEP use (AOR = 0.64) had lower PrEP use intention. In addition, the effects of HBM constructs and specific health beliefs on PrEP use intention varied by preferred penile-anal sexual role. The study findings may inform efforts aimed at improving PrEP acceptability and optimizing PrEP implementation programs tailored for YMSM of different sexual roles.
暴露前预防（PrEP）是预防 HIV 的有效工具，最近已在台湾获得批准。然而，台湾需要更多关于 PrEP 可接受性和有效实施 PrEP 的研究。人们对男男性行为者（MSM）使用 PrEP 的意愿和重要的社会心理因素知之甚少。本研究旨在探讨与台湾年轻男男性行为者（YMSM）使用 PrEP 意愿相关的健康信念。本研究使用健康信念模型（HBM）作为指导框架，通过多种渠道招募参与者进行匿名在线调查，以确保多样性。采用多变量逻辑回归分析与高 PrEP 使用意愿相关的健康信念。对 1329 名 HIV 阴性 YMSM 的数据进行了分析；488 名（36.7%）被归类为具有高 PrEP 使用意愿，这与他们认为自己易感染 HIV 的可能性高[调整后的优势比（AOR）=2.11]、认为 PrEP 使用有很高的益处（AOR=2.14）、PrEP 使用的自我效能感高（AOR=4.19）和与 PrEP 使用有关的许多行动提示（AOR=1.49）有关。认为 PrEP 使用存在很大障碍的 YMSM（AOR=0.64）的 PrEP 使用意愿较低。此外，HBM 结构和特定健康信念对 PrEP 使用意愿的影响因偏好的阴茎-肛门性角色而异。研究结果可能为提高 PrEP 可接受性和优化针对不同性角色的 YMSM 的 PrEP 实施计划提供信息。
