In Taiwan, sexual minority men (SMM) account for a significant portion of new HIV cases, highlighting the need for effective prevention measures. However, pre-exposure prophylaxis (PrEP) use remains limited, necessitating a comprehensive examination of barriers. This study examined PrEP engagement and its predictors among 284 SMM in Taiwan. Participants were categorized into five stages, based on the Transtheoretical Model of Health Behavior Change, reflecting distinct levels of PrEP engagement. Ordinal logistic regression, informed by the Behavioral Model of Health Service Use, identified factors associated with being positioned at higher stages of the cascade. Significant predictors of PrEP engagement included predisposing (i.e., relationship status), enabling (i.e., PrEP knowledge, community connectedness), and need factors (i.e., number of sexual partners, chemsex). Findings highlight the need for further research on education, relationship dynamics, and sexual risk behaviors to inform tailored interventions that enhance PrEP engagement among SMM in Taiwan and the broader Asia region.
在台湾，性少数男性（SMM）占新增艾滋病毒病例的很大一部分，这凸显了采取有效预防措施的必要性。然而，暴露前预防（PrEP）的使用仍然有限，因此有必要对相关障碍进行全面审视。本研究调查了台湾284名性少数男性的PrEP参与情况及其预测因素。根据健康行为改变的跨理论模型，参与者被分为五个阶段，反映了不同程度的PrEP参与情况。基于健康服务利用行为模型进行的有序逻辑回归，确定了与处于级联较高阶段相关的因素。PrEP参与的显著预测因素包括易患因素（即恋爱状况）、促成因素（即PrEP知识、社区联系）和需求因素（即性伴侣数量、化学性行为）。研究结果强调，需要进一步研究教育、恋爱动态和性风险行为，以便为量身定制的干预措施提供信息，从而提高台湾及更广泛亚洲地区性少数男性对PrEP的参与度。
