联合干预模式对男男性行为人群的干预效果评价

Evaluation of effects of combination intervention model to men who have sex with men

目的 评价CDC与男男性行为人群（MSM）活动场所联合干预模式的干预效果。方法 于2009年5月—2010年4月在深圳市4家MSM场所实施为时1年的联合干预，MSM场所向消费人群宣传CDC，CDC派专家或志愿者到场所开展宣教活动，派发安全套、润滑剂、宣传材料并提供咨询检测服务；同期另选3家MSM活动场所作为对照，由志愿者定期到场所发放宣传资料、安全套及润滑剂等。在干预实施前后对联合干预MSM人群（分别为111、120名）、对照MSM人群（分别为105、98名）的艾滋病预防知识、行为进行调查。结果 联合干预实施1年后，MSM人群艾滋病知晓率由73.0％（81/111）上升至91.7％（110/120），最近一次男男肛交性行为中安全套使用率由73.0％（81/111）上升至85.0％（102/120），最近6个月男男肛交性行为从不使用安全套比例由10.8％（11/102）下降至1.7％（2/112），接受安全套（润滑剂）发放的比例由70.3％（78/111）上升至85.0％（102/120），接受同伴教育的比例由10.8％（12/111）上升至24.2％（29/120），接受艾滋病咨询检测的比例由69.4％（77/111）上升至90.8％（109/120）。上述指标在联合干预前后的差异均有统计学意义（P值均〈0.05），而在对照场所干预前后的差异均无统计学意义（P值均〉0.05）。结论 联合干预模式提高了MSM人群的艾滋病预防知识知晓率，降低了其高危行为，是一种有效的干预模式。

Objective This study aimed to explore and evaluate the effects of combination intervention model to men who have sex with men（MSM）.Methods To implement one-year combination intervention in 4 MSM venues during May, 2009 and April,2010. Meanwhile ,3 similar MSM venues were chosen as control. MSM places introduced CDC to consumption crowds.Experts and volunteers sent by CDC undertook health education programme on site and condom,lubricant, pamphlet,consultation,test were provided at the same time. The intervetion measeures applied to control only included providing pamphlet,condom,lubricant by volunteers.Investigations were conducted among subjects of combination intervetion group and control group before（111,120 subjects）and after（105,98 subjects） the intervention with questions related to knowledge and behavior of AIDS prevetion.Results After one-year intervetion,among MSM with combination intervetion,the awareness rate of knowledge level about acquired immune deficiency syndrome （AIDS） increased from 73.0% （81/111）to 91.7% （110/120） , ratio of never-use condom with male decreased from 10.8%（11/102） to 1.7% （2/112）, proportion of condom-use with male at last anal intercourse increased from 73% to 84.7%, percentage of acquiring AIDS-related service and intervention improved significantly, acquiring condom（lubricant） increased from 70.3% （78/111）to 85.0% （102/120）, acquiring peer education increased from 10.8% （12/111）to 24.2% （29/120）,the proportion of acquiring counseling and testing of HIV increased from 69.4% （77/111）to 90.8% （109/120）（all P values 〈0.05）.The above index show no statistic difference before and after the intervetion （all P values 〉0.05） in control MSM venues. Conclusion Combination intervention model was an effective intervention model contributingto an increase in knowledge of AIDS prevetion and decreasing high risk behavior in MSM population.
