Men who have sex with men (MSM), men who have sex with men and women (MSM/W) and transgender women (TGW) remain the populations most severely and disproportionately impacted upon by HIV in Los Angeles County. Baseline data from community-based HIV-prevention programmes serving these populations were analysed to explore differences in demographic characteristics, substance use and sexual partnering between the three groups. Despite high HIV prevalence overall (MSM 34.7% versus MSM/W 16.1% versus TGW 21.9%, p < .001), there were striking differences in risk behaviours. Higher rates of homelessness were reported by MSM/W compared to MSM and TGW. Lower rates of education and less substance use were reported by TGW (62.2%), compared to MSM (79.7%) and MSM/W (92.6%). A much higher number of male sexual exchange partners were reported by TGW (MSM 1.04 [SD = 4.8] versus MSM/W 1.54 [SD = 10.3] versus TGW 12.37 [SD = 23.9], p < .001). Findings support the need for HIV-prevention interventions that specifically address the unique risk patterns among each population in order to curb HIV acquisition and transmission.
男男性行为者（MSM）、男男性行为者和女性（MSM/W）以及跨性别女性（TGW）仍然是洛杉矶县受 HIV 影响最严重和最不成比例的人群。对服务于这些人群的基于社区的艾滋病毒预防方案的基线数据进行了分析，以探讨这三组人群在人口统计学特征、药物使用和性伴关系方面的差异。尽管总体 HIV 感染率很高（MSM 为 34.7%，MSM/W 为 16.1%，TGW 为 21.9%，p<0.001），但风险行为存在显著差异。与 MSM 和 TGW 相比，MSM/W 报告的无家可归率更高。与 MSM（79.7%）和 MSM/W（92.6%）相比，TGW 报告的受教育程度较低且药物使用较少（62.2%）。与 MSM（1.04[SD=4.8]）和 MSM/W（1.54[SD=10.3]）相比，TGW 报告的男性性交换伴侣人数要多得多（12.37[SD=23.9]，p<0.001）。研究结果支持需要采取艾滋病毒预防干预措施，针对每个群体的独特风险模式，以遏制 HIV 的获得和传播。
