目的评估结合自愿咨询检测(VCT)对男男性接触人群(MSM)高危行为综合干预的效果。方法 2008-2010年对南京市MSM人群进行基线、中期及终期调查,比较干预前后MSM人群知识、无保护性肛交等性行为变化情况,采用SPSS 16.0软件进行统计分析。结果基线调查606人,中期616人,终期400人。基线、中期、期终调查比较:最近半年无保护性肛交率由基线调查的58.1%,下降到中期和终期调查的43.2%和49.2%,呈现明显的下降趋势(P<0.05);最近一次肛交过程未使用安全套的比例分别为42.2%、32.5%和36.0%,显著下降(P<0.05);最近半年有多个性伴(>2个)的比例经过干预,由32.3%下降为24.0%(P<0.05);最近半年与女生发生过性行为的比例也呈下降趋势(基线20.8%,中期15.6%,终期15.5%,P<0.05);现症梅毒的感染率从基线的11.4%下降至中期调查的7.5%和终期调查的7.8%(P<0.05)。结论 结合VCT进行MSM人群高危行为综合干预降低了MSM人群的高危性行为和现症梅毒感染率。
Objective To evaluate the effect of VCT combined with high-risk behavioral interventions for men who have sex with men (MSM). Methods From 2008 to 2010, the baseline, intermediate and final surveys of MSM population in Nanjing were conducted. The changes of MSM population knowledge, unprotected anal sex and other sexual behaviors before and after intervention were compared and analyzed by SPSS 16.0 software. Results The baseline survey of 606 people, mid-616, the final 400. Comparison of baseline, interim, and end-of-year surveys: The rate of unprotected anal slippage in the last six months decreased significantly from 58.1% of the baseline survey to 43.2% and 49.2% of the interim and final surveys (P <0.05); the most recent The percentage of non-condom use during anal intercourse was 42.2%, 32.5% and 36.0%, respectively (P <0.05). The proportion of multiple sexual partners (> 2) in the last six months decreased from 32.3% to 24.0% P <0.05). The incidence of sexual behaviors among girls in the recent six months also showed a decreasing trend (baseline 20.8%, mid-term 15.6%, final 15.5%, P <0.05). The prevalence of syphilis decreased from 11.4% To 7.5% in the interim survey and 7.8% in the final survey (P <0.05). Conclusion The combination of VCT and high-risk behavioral intervention in MSM population reduces the risk of syphilis infection in MSM population.
