社会网络对男性流动人口艾滋病风险性行为的影响

Influence of Social Network on HIV Sexual Risk Behaviors Among Male Rural-Urban Migrants

目的:考察社会网络因素对男性流动人口艾滋病风险性行为的影响。方法:运用问卷调查法对生活在北京的男性流动人口开展横断面调查,采用二元logistic回归进行数据分析。结果:在385名调查对象中,139名曾在调查之前的12个月中有过商业性行为,27名在商业性行为中未坚持使用安全套。核心应酬网成员的行为对调查对象的行为具有显著影响。结论:社会网络因素能为解释男性流动人口的艾滋病风险性行为提供显著贡献,核心应酬网的教育异质性和职业异质性分别对商业性行为和安全套使用具有显著影响,加入社会网络变量的统计模型显著提升了对流动人口风险性行为的解释力,未来面向流动人口的艾滋病研究和干预项目应关注社会网络的作用。

Objective ： To investigate the influence of social network factors on HIV sexual risk behaviors among male rural-urban migrants. Methods： A cross-sectional survey was conducted among male rural-urban migrants in Beijing. Binary logistic regression was used to analyze the data. Results： 139 among 385 respondents committed commercial sex in the past 12 months, whereas 27 among 139 reported inconsistent condom use. The behaviors of the members of the core social network had significant influence on the corresponding behaviors of respondents. The educa- tion heterogeneity and job heterogeneity had significant influence on commercial sex and condom use respectively. The statistical model adding so- cial network variables significantly improved the explanation capacity of HIV sexual risk behaviors. Conclusion： Social network factors had significant contribution to the explanation of HIV sexual risk behaviors among rural-urban male migrants. More attention should be paid to social network factors in future studies or intervention programs aimed at male migrants.
