Engagement with HIV-prevention services varies among sexual minority men (SMM). 183 HIV-negative SMM completed a baseline assessment including sociodemographic, psychosocial, identity and stigma, and sexuality measures, as well as HIV-prevention behaviors: (1) date of most recent HIV test, (2) whether they discussed HIV or (3) sexual behavior with their provider, and (4) disclosure to provider about engaging in condomless anal sex (CAS). Factor analysis of these four items yielded an HIV-prevention engagement factor score. Stochastic search variable selection (SSVS) followed by multiple linear regression identified variables associated with HIV-prevention engagement. SSVS identified three variables for inclusion in a multiple linear regression model. Not disclosing sexual orientation to one’s provider (p < 0.001), discomfort discussing sex with provider (p < 0.001) and lower education (p = 0.007) were associated with less HIV-prevention engagement. Findings suggest the importance of training providers in culturally competent care to mitigate observed barriers.

性少数男性 (SMM) 参与艾滋病毒预防服务的情况各不相同。183 名 HIV 阴性 SMM 完成了一项基线评估，包括社会人口学、社会心理、身份和污名、性行为以及 HIV 预防行为：(1) 最近一次 HIV 检测的日期，(2) 他们是否讨论过 HIV 或 (3 ) 与提供者的性行为，以及 (4) 向提供者披露有关进行无避孕套肛交 (CAS) 的信息。这四个项目的因素分析产生了 HIV 预防参与因素得分。随机搜索变量选择 (SSVS) 随后进行多元线性回归确定了与 HIV 预防参与相关的变量。SSVS 确定了三个变量以包含在多元线性回归模型中。不向提供者透露性取向（p < 0.001)、与服务提供者讨论性问题 ( p  < 0.001) 和受教育程度较低 ( p  = 0.007) 与较少的 HIV 预防参与有关。调查结果表明培训提供者在文化主管护理方面的重要性，以减轻观察到的障碍。
