在中国沈阳，2012 年至 2016 年期间，对从未接受过 HIV 检测的男男性行为者进行了一项连续的横断面研究，结果显示，这些人群中无保护肛交和 HIV 感染率呈上升趋势。

Abstract

Despite the high HIV incidence among men who have sex with men (MSM) in China, over half of MSM have never been tested for HIV before (MSMNT). Through a serial cross-sectional study from 2012 to 2016 in Shenyang, China, we studied 1036 MSMNT, and diagnosed 16.2% (168/1036) with HIV. The percentage of MSMNT who had condomless anal intercourse (CAI) in the past year increased from 42.1% (130/309) in 2012 to 63.4% (102/161) in 2016 (P < 0.001). 61.9% (104/168) of HIV-positive MSMNT had CAI and this percentage remained constant for the study period (P = 0.593). 53.3% (463/868) of HIV-negative MSMNT had CAI and this percentage significantly increased over the study period (P < 0.001). Encouraging HIV testing in this key subset through online HIV risk self-evaluation tools and HIV self-testing kits may help mitigate the overall MSM HIV incidence.

摘要

尽管中国男男性行为者（MSM）中的 HIV 感染率很高，但超过一半的 MSM 之前从未接受过 HIV 检测（MSMNT）。通过 2012 年至 2016 年在中国沈阳进行的一项系列横断面研究，我们研究了 1036 名 MSMNT，并诊断出 16.2%（168/1036）患有 HIV。过去一年中无保护肛交（CAI）的 MSMNT 百分比从 2012 年的 42.1%（130/309）增加到 2016 年的 63.4%（102/161）（P<0.001）。61.9%（104/168）的 HIV 阳性 MSMNT 有 CAI，这一比例在研究期间保持不变（P=0.593）。53.3%（463/868）的 HIV 阴性 MSMNT 有 CAI，这一比例在研究期间显著增加（P<0.001）。通过在线 HIV 风险自我评估工具和 HIV 自我检测试剂盒鼓励该关键亚组进行 HIV 检测，可能有助于降低整体 MSM HIV 感染率。
