目的评价鞍山市开展男男性行为人群(MSM)艾滋病综合干预的效果,为下一步制定防治策略提供依据。方法每年通过滚雪球的方式招募不少于400名MSM,进行行为学调查和血清学艾滋病病毒(HIV)抗体检测。采用描述统计和趋势χ2检验分析方法比较各年度数据,对综合效果进行评价。结果 2006-2013年,通过综合干预,鞍山市MSM艾滋病防治知识知晓率从89.05%上升到93.52%;近6个月安全套坚持使用率从46.86%上升到63.14%,近1次安全套使用率从43.21%上升到88.52%,接受干预服务比例从82.86%上升到94.26%,近1年接受HIV抗体检测的比例从20.71%上升到68.83%。2006-2013年,各年HIV感染率分别为0.24%、1.48%、2.94%、4.23%、2.72%、4.25%、5.17%、8.48%,逐年上升趋势显著。结论鞍山市MSM综合干预措施已取得一定成效,但是MSM安全套坚持使用率还处于较低水平,切实采取针对性措施控制HIV通过MSM蔓延刻不容缓。
Objective To evaluate the effect of comprehensive HIV / AIDS intervention in MSM in Anshan City and provide evidence for further prevention and treatment strategies. METHODS: Snowballs were recruited annually for not less than 400 MSM for behavioral investigation and serological HIV antibody testing. Χ2 test described the use of statistical methods and trends to compare the annual data to evaluate the overall effect. Results From 2006 to 2013, through the comprehensive intervention, the awareness rate of MSM AIDS prevention and treatment in Anshan increased from 89.05% to 93.52%; in the recent 6 months, the condom use rate increased from 46.86% to 63.14%, and the condom use rate in the last 1 year increased from 43.21 % To 88.52%, and the percentage of service interventions increased from 82.86% to 94.26%. The percentage of HIV antibody testing in the past year rose from 20.71% to 68.83%. In 2006-2013, the rates of HIV infection in each year were 0.24%, 1.48%, 2.94%, 4.23%, 2.72%, 4.25%, 5.17% and 8.48% respectively. Conclusion The comprehensive MSM intervention in Anshan City has achieved some success, but the MSM condom use rate is still at a low level. It is imperative to take targeted measures to control the spread of HIV through MSM.
