355名饭店女性流动人群性病艾滋病社会网络干预研究

目的探索社会网络干预对预防控制饭店女性流动人群性病艾滋病的可行性和有效性。方法选取合肥市12家饭店和蚌埠市14家饭店,以在饭店打工、农村户口、未婚女性为研究对象,从其中招募48名健康宣传员,将研究对象按与其关系密切程度分成4组,每组6～8人。先对健康宣传员实施干预,再由健康宣传员对其干预组成员进行宣传。比较干预前、后研究对象艾滋病相关知识和行为变化以评估干预效果。结果干预前艾滋病相关知识和安全套使用自我效能平均分分别为：13.87±6.27、11.61±4.19,干预后均增加到23.38±4.97、12.87±4.25;干预前最近两个月、最近1次和最近3次性行为时每次都使用安全套者所占比例分别为：26.9%、46.9%、27.0%,干预后分别为53.7%、63.4%、41.4%;艾滋病咨询机构知晓率和检测机构知晓率在干预前分别为85.4%和64.8%,在干预后分别为98.4%和92.8%;艾滋病咨询报告率和检测报告率在干预前分别为4.1%和6.8%,均低于干预后（19.4%、28.5%）,差异有统计学意义（χ2=37.851,P〈0.01;χ2=54.481,P〈0.01）。结论社会网络干预可有效提高饭店女性流动人群性病艾滋病知识、安全套使用率和规范卫生服务知晓率及利用率,是该人群性病艾滋病预防控制的有效方法。

STDs/AIDS intervention among 355 migrant females working in restaurants

Objective To examine the feasibility and effectiveness of social network based STDs/ AIDS intervention among migrant females working in restaurants. Methods 355 unmarried females were selected from restaurants in Hefei and Bengbu by convenience sampling, who moved from rural areas to cities. 48 peer educators were recommended and others were divided into 48 groups according to the relationship with peer educators. Peer educators were trained, and meanwhile they shared what they had learnt with other members. Questionnaires were completed pre- and post-intervention to assess effectiveness of intervention. Results The average score of knowledge related to AIDS and self-efficacy of condom use was increased after intervention （pre-intervention： 13.87 ± 6.27,11.61 ± 4.19; post-intervention： 23.38 ± 4.97,12.87 ± 4.25 ; P 〈 0.01 ）. The rate of condom use in every intercourse was increased in the last two months, last time and last three times after intervention （pre-intervention： 26.9% ,46.9% ,27.0% ; post-intervention： 53.7% ,63.4% ,41.4% ; P〈0.05）. The rates of HIV consultation and testing were increased （ pre-intervention： 4.1%, 6.8 % ; post-intervention： 19.4 %, 28.5 % ; P 〈 0.01）. Conclusions Social network based STDs/AIDS intervention is feasible and effective among migrant females working in restaurants.
