四川省某市中老年男性亲密社会网络特征及其与HIV感染的关系研究

The characteristics of intimate social network and its relationship with HIV infection among middle-aged and elderly men in Sichuan Province

目的 描述四川省某市中老年男性亲密社会网络特征,探讨其对中老年男性感染HIV的影响。方法 采用病例对照研究(1∶4同龄匹配),运用访谈式问卷调查,获取调查对象人口学特征、亲密社会网络等信息,采用条件Logistic回归进行数据分析。结果 病例组的亲密社会网络成员数和获得物质支持[4(0,7),(80.23%)]多于对照组[3(0,5)个,50.57%],病例组与对照组调查对象从未与第一亲密网络成员谈论私密话题的比例(53.49%,50.00%),从未谈论艾滋病相关知识(95.35%,93.18%)均较高。存在异性商业性性行为(OR=37.493)、同性性行为(OR=15.327)、每月个人收入≥3 000元(OR=2.283)、亲密网络规模大(OR=1.237)、偶尔、经常、总是从第一亲密网络成员处获得物质支持者(OR=2.454、3.014、3.488)为HIV感染者的概率更高;接受过艾滋病相关知识宣传者(OR=0.385)为HIV感染者的概率更低。结论 中老年男性与亲密社会网络成员谈论私密话题及艾滋病相关知识的话题亲密度均不高。但病例组的亲密社会网络规模更大、获取的物质支持更多。可通过政府、家庭及个人层面共同努力,帮助中老年男性构建规模适度、稳定可靠的亲密社会网络。针对中老年男性较亲近人员加强性健康教育,提高其感染HIV的风险意识,避免感染HIV。

Objective To describe the characteristics of the intimate social network and its impact on HIV infection among middle-aged and elderly men in the city of Sichuan Province. Methods We conducted a case-control study(1∶4ratio age matching). An interview questionnaire was used to obtain demographic characteristics, intimate social networks and other information about the respondents. A conditional logistic regression was used for data analysis. Results The number of intimate social network members and material support in the case group [4(0, 7),(80.23%)] was more than those in the control group [3(0,5), 50.57%]. The proportion of participants who never talked about private topics with the first intimate network member(53.49%, 50.00%) and the proportion of participants who never talked about AIDS-related knowledge(95.35%, 93.18%) were both high in the two groups. People who were more likely to be HIV infected included those with the behavior of heterosexual commercial sex(OR=37.493), homosexual sex(OR=15.327), monthly personal income ≥ 3000 Yuan(OR=2.283), a large intimate network(OR=1.237), and occasional, frequent and always obtaining material support from the first intimate network member(OR=2.454, OR=3.014, OR=3.488). People who have received AIDS-related knowledge propaganda(OR=0.385) were less likely to be HIVinfected. Conclusions The intimate degree of talking about private topics and AIDS-related knowledge with members of intimate social networks among middle-aged and elderly men was not high. However, the intimate social network of the case group was larger, and more material support was obtained. Through joint efforts from the government, families, and individuals, we can help middle-aged and elderly men build an appropriate, stable, and reliable intimate social network. We should strengthen sexual health education for those who are close to middle-aged and elderly men and improve their awareness of HIV infection in order to reduce their risk of HIV infection.
