Study of HIV/AIDS-related sexual behaviors and influencing factors among migrants in Shenzhen,China

目的了解深圳市流动人口的艾滋病相关行为及影响因素,为后续干预活动提供政策性建议。方法在深圳市盐田、罗湖、福田三区开展问卷调查。统计分析方法主要包括χ2检验和Logistic回归分析,统计软件采用SAS 8.02软件包。结果本次研究共调查1 014名对象,86.79%的调查对象年龄集中在20～40岁之间,812名对象有性生活。流动人口多性伴比例为47.41%,女性多性伴的危险性低于男性(OR=0.40,95%CI:0.28-0.56),首次性行为对象为非配偶的对象其多性伴的可能性高于首次性行为对象为配偶的对象(OR=3.87,95%CI:2.72-5.51)。有52.46%的研究对象近一年性生活中使用安全套,单因素分析显示不同性别、不同学历、不同收入、不同户口性质、不同艾滋病知识总分、不同的首次性行为对象以及不同性伴数量的对象,其安全套使用的比例有统计学差异。多因素结果显示性别、知识总分是安全套使用的主要影响因素。与男性相比,女性使用安全套的比例较低(OR=0.47,95%CI:0.34-0.65);与知识总分在60分以下的研究对象相比,知识总分在60分以上的研究对象使用安全套的比例高(OR=2.49,95%CI:1.84-3.36)。结论流动人口中普遍存在艾滋病相关高危行为,建议多部门协调合作,加强流动人口群体的艾滋病防治知识和保护意识的宣传,特别是对男性、首次性行为为非配偶的对象、艾滋病知识较低的对象进行干预。
