以前的研究已经记录了男男性行为者（MSM）中艾滋病毒流行率的种族差异，即使在调整传统风险因素之后。在1999-2000年洛杉矶青年男性调查（一项针对23-29岁男男性接触者的基于场所的横断面调查）中收集的数据分析中，我们调查了男性性伴侣特征的信息是否解释了HIV流行率的一些种族/民族差异。在这个调查参与者的样本中，我们观察到，非洲裔美国男男性接触者报告的艾滋病毒风险行为水平与白色男男性接触者相似或更低，但艾滋病毒感染率要高得多（分别为26%和7.4%）。在一个未经调整的逻辑回归模型中，非裔美国人参与者的艾滋病毒感染几率是白色参与者的4.4倍。在调整参与者行为的多元逻辑回归模型中，我们观察到非裔美国人与白人相比HIV感染的相对几率升高（比值比[OR] = 6.9，95%置信限[CL] = 2.5，19）。在一个完全调整的模型中，控制了老年伴侣和更多非洲裔美国人伴侣的影响，我们观察到非洲裔美国人参与者与白色参与者相比，艾滋病毒的相对几率降低了20%（OR = 5.5，95%CL = 1.8，17）。我们的研究结果表明，男性伴侣类型的差异，即老年人和非洲裔美国人的合作伙伴，可能会解释一些观察到的艾滋病毒感染的种族差异，特别是非洲裔美国人的男男性接触者相比，白色男男性接触者在洛杉矶。
Previous studies have documented disparities in HIV prevalence by race among men who have sex with men (MSM), even after adjusting for traditional risk factors. In this analysis of data collected for the 1999-2000 Los Angeles Young Men's Survey, a cross-sectional venue-based survey of MSM aged 23-29, we investigated whether information on male sex-partner characteristics accounts for some of the racial/ethnic differences in HIV prevalence. In this sample of survey participants, we observed that African American MSM reported similar or lower levels of HIV risk behaviors compared with White MSM but much higher HIV prevalence (26% vs. 7.4%, respectively). In an unadjusted logistic regression model, African American participants had 4.4 times higher odds of HIV infection compared with White participants. In a multiple logistic regression model adjusting for participant behaviors, we observed elevation of the relative odds of HIV infection for African Americans compared with Whites (odds ratio [OR] = 6.9, 95% confidence limits [CL] = 2.5, 19). In a fully adjusted model, controlling for the effects of having older partners and more African American partners, we observed a 20% reduction in the relative odds of HIV for African American participants compared with White participants (OR = 5.5, 95% CL = 1.8, 17). Our findings suggest that differences in male partner types, namely older and African American partners, may account for some of the observed racial disparity in HIV infection, especially for African American MSM compared with White MSM in Los Angeles.
