HIV prevalence is high among transgender women (TW), but how HIV is transmitted to this population is not well understood. This analysis aims to characterize sexual partners of TW (PTW) to understand how their behavior contributes to HIV risk among TW. We examined baseline data from TW, PTW, and men who have sex with men (MSM) from a treatment-as-prevention study in Lima, Peru. Individual and partnership characteristics were compared across groups, and Poisson regression was used to calculate prevalence ratios for associations between sexual concurrency and potential correlates. We found that 81% of PTW had no cisgender male partners. Prevalence of alcohol dependency, concurrency, and condomless anal intercourse was high and HIV testing was low compared to the other groups. Our results suggest that PTW are a distinct population from MSM and TW, engage in behavior associated with HIV transmission, and are likely not well reached by HIV prevention interventions.
跨性别女性（TW）中的艾滋病毒流行率很高，但艾滋病毒如何传播到这一人群尚未得到充分了解。本分析旨在描述跨性别女性的性伴侣（PTW）特征，以了解他们的行为如何导致跨性别女性中的艾滋病毒风险。我们研究了来自秘鲁利马一项治疗即预防研究中的跨性别女性、跨性别女性的性伴侣和男男性行为者（MSM）的基线数据。对各组的个人和伴侣特征进行了比较，并使用泊松回归计算性伴重叠与潜在相关因素之间关联的患病率比。我们发现，81%的跨性别女性的性伴侣没有顺性别男性。与其他组相比，酒精依赖、性伴重叠和无保护肛交的患病率很高，而艾滋病毒检测率很低。我们的结果表明，跨性别女性的性伴侣与男男性行为者和跨性别女性是不同的人群，他们的行为与艾滋病毒传播有关，而且艾滋病毒预防干预措施可能无法很好地覆盖到他们。
