目标.本研究探讨了影响艾滋病毒预防研究中时空抽样可行性的方法学问题，这些研究的目标是难以接触到的少数男青年（MSM）。我们在纽约市32个年轻的拉丁裔男男性接触者聚集的场所对400名男性进行了采访。响应率和人口和性风险概况进行比较的场地类型。超过90%的男性接受了筛查。在符合条件的男子中，参与率超过82%。特别活动和同性恋场所的参与率高于非同性恋场所（P <0.05）。在非同性恋场所的年轻男男性接触者不太可能自我认同为同性恋（P < .01）或报告最近与男性发生肛交（P < .10）。避孕套的使用并不因场所类型而异，但女性的使用率低于男性。如果调查仅限于同性恋场所，在非同性恋场所接受调查的年轻男男性接触者中约有一半会被遗漏。一个相对“隐藏”的少数年轻男男性接触者人口的调谐空间采样可以在一系列场所成功。然而，必须权衡扩大外联的好处和在非政府场所招募参与者的费用。
Objectives. This study addressed methodological issues influencing the feasibility of time-space sampling in HIV prevention studies targeting hard-to-reach populations of minority young men who have sex with men (MSM).Methods. We conducted interviews with 400 men in 32 venues where young Latino MSM congregate in New York City. Response rates and demographic and sexual risk profiles are compared by venue type.Results. More than 90% of the men approached were screened. Among eligible men, participation rates exceeded 82%. Participation was higher at special events and gay venues compared with nongay venues (P < .05). Young MSM in nongay venues were less likely to self-identify as gay (P < .01) or to report recent anal sex with a male (P < .10). Condom use did not vary by venue type but was lower with women than with men. If surveys had been limited to gay venues, about half of the young MSM surveyed in nongay venues would have been missed.Conclusions. Tune-space sampling of a relatively "hidden" minority young MSM population can be successful across a range of venues. However, the benefits of greater outreach must be weighed against the costs incurred recruiting participants in nongay venues.
