HIV and AIDS incidence in China is high among men who have sex with men (MSM) and ours was one of few studies in China to evaluate the role of HIV risk reduction counseling and testing. Respondent-driven sampling (RDS) was used to recruit 430 MSM. Participants were followed up at 6, 12 and 18 months to evaluate behavioral changes after counseling to reduce risk behaviors. At baseline, HIV prevalence was 4.7%, whereas HIV incidence was 5.2 per 100 person-years. The incidence was 3.8 during six to 12 months, and 1.1 during 12 to 18 months. During the study period, the reported unprotected anal intercourse (UAI) significantly decreased from 60.9% to 42.9%. The proportion of participants who had one or no partner significantly increased from 40.9% to 48.0%. The study also found that some risk behaviors decreased between baseline and 12 months, followed by a slight increase between 12 and 18 months. Reductions in UAI can be achieved through counseling and testing, but may wane over time. Future programs should consider HIV risk-reduction counseling and testing for interventions in MSM in China.
中国男男性行为人群（MSM）中的艾滋病毒（HIV）和艾滋病发病率较高，我们的研究是中国少数评估 HIV 风险降低咨询和检测作用的研究之一。我们采用 respondent-driven sampling (RDS) 方法招募了 430 名 MSM。参与者在 6、12 和 18 个月时进行随访，以评估咨询后降低风险行为的行为变化。基线时 HIV 感染率为 4.7%，HIV 发病率为 5.2 例/100 人年。6-12 个月期间发病率为 3.8%，12-18 个月期间发病率为 1.1%。在研究期间，报告的无保护肛交（UAI）显著从 60.9%下降到 42.9%。有一个或没有性伴侣的参与者比例从 40.9%显著增加到 48.0%。研究还发现，一些风险行为在基线和 12 个月之间有所减少，随后在 12 至 18 个月之间略有增加。通过咨询和检测可以实现减少 UAI，但随着时间的推移可能会减弱。未来的项目应考虑在中国 MSM 中进行 HIV 风险降低咨询和检测干预。
