The randomized controlled trial investigated the relative efficacy of an enhanced (EVCT) versus standard (SVCT) voluntary counseling and testing in reducing unprotected anal intercourse (UAI) among men who have sex with men (MSM) in China. 295 participants who recruited by respondent driven sampling methods were randomly allocated to the two arms. In addition to the SVCT, the EVCT group watched a theory-based video narrated by a HIV positive MSM, received enhanced counseling and a reminder gift. As compared to the SVCT group, the EVCT group reported lower prevalence of UAI with any male sex partners (48.4% versus 66.7%, RR = 0.7, ARR = -18.3%, p = 0.010) and with regular male sex partners (52.2% versus 68.9%, RR = 0.8, ARR = -16.7%, p = 0.043) at Month 6, whilst baseline between-group differences were statistically non-significant. Between-group differences in HIV/syphilis incidence were statistically non-significant. Translational research should be conducted to integrate non-intensive enhancements such as the EVCT into regular testing services.
这项随机对照试验研究了强化（EVCT）与标准（SVCT）自愿咨询检测在减少中国男男性行为者（MSM）无保护肛交（UAI）方面的相对效果。通过应答驱动抽样方法招募的 295 名参与者被随机分配到两组。除了 SVCT，EVCT 组还观看了一个由 HIV 阳性 MSM 讲述的基于理论的视频，接受了强化咨询和提醒礼物。与 SVCT 组相比，EVCT 组报告的与任何男性性伴侣发生 UAI 的比例较低（48.4%对 66.7%，RR=0.7，ARR=-18.3%，p=0.010），与固定男性性伴侣发生 UAI 的比例也较低（52.2%对 68.9%，RR=0.8，ARR=-16.7%，p=0.043），而 6 个月时组间差异无统计学意义。HIV/梅毒发病率的组间差异无统计学意义。应进行转化研究，将 EVCT 等非强化措施纳入常规检测服务。
