In a cross-sectional study, MSM aged ≥18 years were venue-sampled in New York City in 2008, interviewed, and tested for HIV using oral fluids. Participants who reported testing HIV negative at their last test in the previous 24 months were analyzed (n = 287 of 550 sampled). Those testing positive at the interview were defined as recently infected. HIV incidence was estimated using person-time at-risk methods and correlates of recent infection using proportional hazards regression. Thirty-two (11.1%) were recently infected. HIV incidence was 5.67/100 person-years at-risk. Independent correlates included: study recruitment in parks vs. bars, and in other venues vs. bars; black vs. non-black race/ethnicity; and reporting a last sex partner with a positive or unknown vs. negative HIV status. When assay-based methods are not feasible, cross-sectional HIV test results and self-reported HIV testing history and risk factor data can be used to estimate HIV incidence and the correlates of recent infection.
在一项横断面研究中，2008 年在纽约市对年龄≥18 岁的男男性行为者进行了现场抽样调查，通过口腔液进行了 HIV 检测。对在过去 24 个月内最后一次检测结果为 HIV 阴性的参与者进行了分析（550 名抽样者中有 287 名）。在访谈中检测结果为阳性的被定义为最近感染。使用风险人群时间法估计 HIV 发病率，并使用比例风险回归分析最近感染的相关因素。有 32 人（11.1%）最近感染。HIV 发病率为每 100 人年风险人群 5.67 例。独立相关因素包括：在公园而不是酒吧、在其他场所而不是酒吧进行研究招募；黑人而不是非黑人种族/民族；以及报告最后一名性伴侣的 HIV 状态为阳性或未知，而不是阴性。当基于检测方法不可行时，可以使用横断面 HIV 检测结果以及自我报告的 HIV 检测史和风险因素数据来估计 HIV 发病率和最近感染的相关因素。
