An estimated 35-68% of new HIV infections among gay, bisexual, and other men who have sex with men (GBM) are transmitted through main partnerships. Pre-exposure prophylaxis (PrEP) is highly effective in reducing HIV seroconversion, yet PrEP uptake has been modest. PrEP-naïve GBM with HIV-negative, PrEP-naïve main partners enrolled in One Thousand Strong (n = 409), a U.S. national cohort of GBM, were asked about (1) the importance of partner PrEP use and (2) their willingness to convince their partner to initiate PrEP. On average, participants thought partner PrEP was only modestly important and were only moderately willing to try to convince their partner to initiate PrEP. Personal PrEP uptake willingness and intentions were the strongest indicators of partner PrEP outcomes. Being in a monogamish relationship arrangement (as compared to a monogamous arrangement) and the experience of intimate partner violence victimization were associated with increased willingness to persuade a partner to initiate PrEP.
据估计，男同性恋、双性恋和其他与男性发生性关系的男性（GBM）中新感染艾滋病毒的人数中，有 35%-68%是通过主要性伴侣传播的。暴露前预防（PrEP）在降低艾滋病毒血清转化方面非常有效，但 PrEP 的使用率一直较低。在美国的一项全国性 GBM 队列研究“一千强”（One Thousand Strong）中，有 PrEP 初治、艾滋病毒阴性、PrEP 初治的主要性伴侣的 409 名 GBM 参与者被问及（1）伴侣使用 PrEP 的重要性，以及（2）他们是否愿意说服伴侣开始使用 PrEP。平均而言，参与者认为伴侣使用 PrEP 只是适度重要，并且只是适度愿意尝试说服伴侣开始使用 PrEP。个人使用 PrEP 的意愿和意图是伴侣 PrEP 结果的最强指标。处于一夫一妻制（与一夫一妻制相比）和亲密伴侣暴力受害经历的关系安排与增加说服伴侣开始使用 PrEP 的意愿有关。
