非裔男男性行为者(MSM)感染艾滋病毒的比例更高，占美国所有感染艾滋病毒的MSM的一半以上。利用纽约市一项多地点研究的数据，评估了三种艾滋病毒检测策略对以前未诊断的18岁非裔美国人MSM的检测效果。有效性被定义为对血清阳性个体的识别。我们使用准实验设计(N=558)，检查了通过替代场所测试、社交网络策略、伴侣咨询和转介服务被测试的男性的HIV阳性检测结果，以及通过替代场所测试和社交网络策略被测试的509名男性的行为风险因素。HIV阳性的检测率为：替代场所测试-6.3%，社交网络策略-19.3%，伙伴服务-14.3%。与其他地点检测相比，社交网络策略检测到HIV阳性MSM的几率高出3.6倍，合作伙伴服务的几率高出2.5倍。通过替代场所测试的男性比通过社交网络策略测试的男性更年轻，更有可能被识别为同性恋。通过社交网络策略测试的男性报告的性危险行为比通过另一种地点测试的男性更多。研究结果表明，测试策略的有效性有所不同。考虑到不同战略中获得检测的个体的不同，可能需要采取多策略检测方法来最充分地识别未诊断的艾滋病毒阳性非裔美国男男性接触者。
African American men who have sex with men (MSM) are disproportionately affected by HIV and constitute more than half of all HIV-infected MSM in the USA.Data from the New York City location of a multi-site study were used to evaluate the effectiveness of three HIV testing strategies for detecting previously undiagnosed, 18 to 64-year-old African American MSM. Effectiveness was defined as the identification of seropositive individuals.Using a quasi-experimental design (N = 558), we examined HIV-positive test results for men tested via alternative venue testing, the social networks strategy, and partner counseling and referral services, as well as behavioral risk factors for 509 men tested through alternative venue testing and the social networks strategy.Detection rates of HIV-positives were: alternative venue testing-6.3%, the social networks strategy-19.3%, and partner services-14.3%. The odds for detection of HIV-positive MSM were 3.6 times greater for the social networks strategy and 2.5 times greater for partner services than alternative venue testing. Men tested through alternative venue testing were younger and more likely to be gay-identified than men tested through the social networks strategy. Men who tested through the social networks strategy reported more sexual risk behaviors than men tested through alternative venue testing.Findings suggest differential effectiveness of testing strategies. Given differences in the individuals accessing testing across strategies, a multi-strategic testing approach may be needed to most fully identify undiagnosed HIV-positive African American MSM.
