Black gay, bisexual, and other Black sexual minority men (BSMM) continue to experience some of the largest sexual health disparities in the U.S. Engaging BSMM in PrEP is crucial to improving sexual health outcomes and reducing disparities. However, knowledge of the profiles of sexual risk and PrEP initiation among this group is limited. This study used latent class analysis to identify HIV risk and PrEP initiation patterns among BSMM in the HPTN 073 Study (n = 226). Guided by current Centers for Disease Control screening guidelines, latent class indicators included relationship status, condom use, number of sexual partners, substance use, sexually transmitted infection (STI) history, and partner HIV status. Age and PrEP initiation were used in a multinomial regression to identify correlates of class membership. Three latent classes were identified: Single, Condomless Partners, Single, Multiple Partners, and Serodiscordant Partners. Single, Condomless Partners had the highest conditional probabilities of having greater than three male partners, substance use before sex, and receiving an STI diagnosis. Serodiscordant Partners had a 100% conditional probability of condomless sex and having a male partner living with HIV. BSMM who initiated PrEP were less likely to be classified as Single, Condomless Partners than Serodiscordant Partners (AOR = 0.07, 95% CI = 0.02, 0.66). Findings support the need for culturally relevant tailored and targeted messaging for BSMM with multiple sexual risk indicators.
黑人男同性恋、双性恋和其他性少数群体男性(BSMM)继续经历着美国最大的一些性健康差距。让 BSMM 参与 PrEP 是改善性健康结果和减少差距的关键。然而,人们对这一群体的性风险和 PrEP 起始情况的了解有限。本研究使用潜在类别分析来确定 HPTN 073 研究中的 BSMM 的 HIV 风险和 PrEP 起始模式(n=226)。在当前疾病控制中心的筛查指南的指导下,潜在类别指标包括关系状况、 condom 使用、性伴侣数量、物质使用、性传播感染(STI)史和伴侣 HIV 状况。年龄和 PrEP 起始用于多项回归分析,以确定类别成员的相关性。确定了三个潜在类别:单身、无 condom 伴侣、单身、多个伴侣和性伴侣 HIV 不一致。单身、无 condom 伴侣具有更高的条件概率,即拥有大于三个男性伴侣、性前使用物质和收到 STI 诊断。性伴侣 HIV 不一致的伴侣有 100%的 condomless 性行为和有男性伴侣携带 HIV 的条件概率。开始接受 PrEP 的 BSMM 比性伴侣 HIV 不一致的人更不可能被归类为单身、无 condom 伴侣(AOR=0.07,95%CI=0.02,0.66)。这些发现支持需要针对具有多种性风险指标的 BSMM 提供文化相关的定制和有针对性的信息。
