我国部分地区MSM艾滋病健康教育效果的Meta分析

Meta-analysis on effectiveness of HIV/AIDS intervention among MSM in China

目的系统评价中国部分地区男男性行为人群(MSM)艾滋病健康教育的效果,探讨可能影响艾滋病干预效果的因素。方法对纳入的30篇文献采用Meta分析进行综合定量分析。结果干预后,"正确使用安全套可以减少艾滋病传播"、"感染了艾滋病病毒的人能否从外表上看出来"的知晓率分别提高了11%与20%;"最近6个月与男性发生肛交性行为时每次坚持使用安全套的比例"、"最近一次性行为使用安全套的比例"、"最近一年做过HIV检测的比例",分别提高了15%、17%、23%。亚组分析表明,大多分组仍存在异质性,五个指标均呈现如下特点:基线率越低,干预效果越好;同伴教育的效果好于一般健康教育;年龄越小,效果越差;未婚构成比越高,效果越差;干预时间长短对干预效果的影响不确定。结论中国对MSM开展的艾滋病干预具有较好的效果,知晓的基线率、是否采取同伴教育、年龄、婚姻状况可能是干预效果的影响因素。

Objective To systematically evaluate the effectiveness of HIV/AIDS intervention among men who have sex with men （MSM） in China and study the possible influence factors. Methods A total of 30 studies were analyzed by meta-analysis method. Results The analysis showed that rate difference （RD） of knowledge on effect of condoms for HIV prevention and RD of knowing ＂HIV infection not visual recognition＂ was 11 % and 20 %. RD of proportion of consistent condom use in the sex activities in the latest six months, RD of proportion of condom use in the latest sex activity and RD of testing rate of HIV in the latest year was 15%, 17 % and 23 %, After stratified a- nalysis, we knew that heterogeneity still existed but indicted that with lower baseline rate, intervention effect was better; with peer education involved, intervention effect was better; with lower age, intervention effect was worse; with higher unmarried proportion, the effect of intervention was worse. The impact of the length of intervention time was uncertain. Conclusion Interventions for preventing HIV/AIDS among MSM is positively effective. Base- line rate, peer education, MSM age and unmarried proportion may be influencing factors.
