We compared perceptions of partner HIV status to HIV test results in a cross-sectional study of sexual networks of men who have sex with men (MSM) in Atlanta. We then examined differences between black and white MSM in the predictive value of perceived partner status. We recruited men ("seeds") using time-space venue sampling. These seeds then referred up to three partners, who could also refer partners. All participants reported sexual behavior and HIV status for recent partners and received HIV tests. For partners who enrolled, we compared laboratory diagnoses to their partner's perception of their status. Black MSM who perceived themselves to be HIV negative were more likely than perceived-negative white MSM to have a positive partner among those they perceived to be HIV negative or whose status was unknown to them (OR=6.6). Furthermore, although frequency of unprotected anal intercourse (UAI) was similar by race, black men were more likely to have had UAI with an unknown-positive partner (OR=9.3).
在亚特兰大对男男性行为者（MSM）性网络进行的一项横断面研究中，我们比较了对性伴侣HIV状况的认知与HIV检测结果。然后，我们研究了黑人和白人男男性行为者在性伴侣状况认知预测价值方面的差异。我们使用时空场所抽样法招募男性（“种子”）。这些“种子”随后可推荐至多三名性伴侣，而这些性伴侣也可以推荐其他性伴侣。所有参与者均报告了近期性伴侣的性行为及HIV状况，并接受了HIV检测。对于登记的性伴侣，我们将实验室诊断结果与其性伴侣对其状况的认知进行了比较。自认为HIV阴性的黑人男男性行为者，比起自认为HIV阴性的白人男男性行为者，在那些他们自认为HIV阴性或其状况未知的性伴侣中，更有可能拥有HIV阳性的性伴侣（比值比=6.6）。此外，尽管无保护肛交（UAI）的频率在不同种族间相似，但黑人男性更有可能与状况未知的HIV阳性性伴侣发生无保护肛交（比值比=9.3）。
