作者研究了年轻的黑人和拉丁裔男男性行为者（MSM）是否比那些没有老年性伴侣的人更有可能感染未被发现的艾滋病毒。作者研究了这种关联是否源于(1)与任何年龄的男性伴侣的性风险行为增加，(2)老年伴侣暴露于艾滋病毒感染的风险增加，或者(3)这两个因素的结合。方法分析样本为723例18-35岁的黑人和拉丁裔男男性行为者，在研究开始时HIV阴性或血清状态未知。参与者完成了一份自我管理的问卷，并进行了艾滋病毒感染检测。报告称有比自己年长至少4岁的男性性伴侣的男性与没有报告的男性进行了比较。结果包括与任何年龄（过去3个月）的男性伴侣进行无保护的接受性肛交（URAI），以及未被识别的艾滋病毒感染。结果伴侣年龄较大的男性报告的URAI患病率较高（AOR=1.50, 95% CI 1.02 ~ 2.21）。第二个模型发现，在控制了任何年龄的URAI伴侣数量（这仍然是一个独立的预测因子）后，伴侣年龄较大的男性感染未被识别的艾滋病毒的几率增加（AOR=2.51, 95% CI 1.18至5.34）。结论年轻的黑人和拉丁裔男男性行为者与年龄较大的男性性伴侣发生未被发现的HIV感染的风险增加。这种增加的风险与与任何年龄的伴侣发生的性危险行为以及可能增加的老年伴侣感染艾滋病毒的风险有关。
Objectives The authors examine whether young black and Latino men who have sex with men (MSM) who have older sex partners are more likely than those who do not have older sex partners to have unrecognised HIV infection. The authors examine whether the association stems from (1) increased sexual risk behaviour with male partners of any age, (2) heightened risk of being exposed to HIV infection by older partners or (3) a combination of these two factors.Methods The analytical sample consisted of 723 black and Latino MSM, aged 18-35 years, who were HIV negative or of unknown serostatus at study entry. Participants completed a self-administered questionnaire and were tested for HIV infection. Men who reported having a male sex partner who was at least 4 years older than themselves were compared with those who did not. Outcomes included unprotected receptive anal intercourse (URAI) with male partners of any age (past 3 months) and having unrecognised HIV infection.Results Men with older partners reported a higher prevalence of URAI (AOR=1.50, 95% CI 1.02 to 2.21). A second model found that men with older partners had increased odds of having unrecognised HIV infection (AOR=2.51, 95% CI 1.18 to 5.34) after controlling for the number of URAI partners of any age, which remained an independent predictor.Conclusions Young black and Latino MSM who had older male sex partners were at increased risk of having unrecognised HIV infection. This heightened risk was associated with sexual risk behaviour with partners of any age as well as possible increased exposure to HIV infection from older partners.
