我国吸毒人群艾滋病预防干预效果的Meta分析

目的 综合评价我国吸毒人群艾滋病预防干预效果,为在吸毒人群中进行艾滋病预防干预提供依据.方法 计算机检索中国生物医学文献光盘数据库(CBM)、中国学术期刊网全文数据库(CNKI)、PubMed、中文科技期刊全文数据库(VIP)、万方数据库等,收集1999～2008年国内外公开发表的关于我国吸毒人群艾滋病预防干预研究的文献并使用RevMan4.2软件对检索并入选的国内16篇文献进行综合定量的Meta分析.结果 经干预后,吸毒人群对"是否知晓共用注射器可以传播艾滋病"(知识点1)、"是否知晓正确使用安全套可以预防艾滋病"(知识点2)的知晓率分别提高了23%(0.16～0.30)和13%(0.09～0.17)."最近一个月与别人共用注射器的比例"(共针率)降低了24%(0.18～0.30).结论 我国对吸毒人群开展的艾滋病预防干预措施具有较好的效果.

Meta Analysis: Effects on HIV/AIDS Intervention in Drug Users

Objective To evaluate the effect of interventions for preventing HIV/AIDS in drug users and provide a basis for future intervention. Methods A computerized literature search was carried out in Chinese Biomedical Database (CBM),Chinese National Knowledge Infrastructure (CNKI) ,PubMed,VIP (Chinese) and Wanfang (Chinese) data-bases to collect articles published between 1999 and 2008 concerning the effect of HTV/AIDS intervention in drug-users. The software RevMan4. 2 was employed to analyze the outcomes of sixteen studies. Results Analysis showed that rate different (RD) of awareness on sharing syringes as HTV transmission route and awareness on condom use for HIV prevention were 23% (0. 16 ～0.30) and 13% (0.09 ～0.17) respectively and RD for proportion of sharing needles and syringes during the most recent month was 24% (0.18 ～0.30). Conclusion Interventions on HTV/AIDS prevention in China among drug-users was positively effective.
