使用多点随机对照研究（INSPIRE）的基线数据，我们将999名HIV阳性注射吸毒者根据其性伴侣的血清状态分为三组。我们的数据提供了一些证据，血清分选发生在我们的样本;约40%的样本有性行为完全与艾滋病毒阳性的合作伙伴，其中约一半的人报告说，与这些合作伙伴的无保护措施的性行为。20%的人只与艾滋病毒阴性的伴侣发生性关系;他们的性行为往往风险最小，约三分之二的人报告他们的性行为受到保护。然而，我们还发现，另外40%的人至少有一个艾滋病毒感染状况不明的伴侣，其中性和毒品风险最高。她们的能力也最低，表现出可能损害艾滋病毒预防的特征。其中一些研究结果与MSM研究结果一致，表明主要是异性恋的注射吸毒者和MSM之间的伴侣选择做法相似。
Using baseline data from a multi-site, randomized controlled study (INSPIRE), we categorized 999 HIV-positive IDUs into three groups based on serostatus of their sex partners. Our data provide some evidence for serosorting occurring in our sample; about 40% of the sample had sex exclusively with HIV-positive partners, and about half of them reported having unprotected sex with these partners. Twenty per cent had sex exclusively with HIV-negative partners; their sexual behaviors tended to be least risky with about two-thirds reporting their sex was protected. However, we also found that another 40% had at least one partner of unknown HIV status and sexual and drug risk was the highest among them. They were also least empowered, showing attributes that may undermine HIV prevention. Some of these findings are consistent with findings from MSM studies, suggesting that partner selection practices are similar between primarily heterosexual IDUs and MSM.
