Abstract:

目的了解亲密社会网络与性网络对四川省彭州市≥50岁男性HIV感染的影响，为中老年HIV/AIDS防控策略制定提供参考依据。方法采用病例对照研究方法，对2019年4月至2020年10月彭州市新报告≥50岁男性病例组114人和经年龄频数匹配的健康对照组423人进行访谈式问卷调查，采用非条件逐步logistic回归分析HIV感染的影响因素。结果在病例组中，亲密社会网络规模和性网络规模≥4人的分别占63.16%（72/114）和96.49%（110/114），高于对照组的23.40%（99/423）和11.58%（49/423）（均P<0.05）。病例组的亲密社会网络与性网络重叠的占49.12%（56/114），低于对照组的82.27%（348/423）（P<0.05）。Logistic回归分析显示，亲密社会网络规模≥4人（OR=8.66，95%CI：2.01~37.30）、性网络规模≥4人（OR=1 121.11，95%CI：28.38~4 429.61）、第1个亲密网络成员给予物质支持（OR=6.39，95%CI：1.03~39.75）、多性伴并存（OR=55.50，95%CI：6.22~494.96）是≥50岁男性感染HIV的危险因素；接受过艾滋病知识宣传（OR=0.07，95%CI：0.01~0.37）、与第1个性网络成员有满意的性生活、有好的日常关系（OR=0.02，95%CI：0.01~0.59；OR=0.01，95%CI：0.01~0.26）、亲密社会网络与性网络重叠（OR=0.02，95%CI：0.01~0.38）是≥50岁男性感染HIV的保护因素。结论亲密社会网络与性网络重叠可减少≥50岁男性感染HIV的风险，应帮助中老年人构建良好且稳定的亲密社会网络和性网络，满足社会交往需求，为预防HIV感染减少高危性行为。

Objective To understand the impact of intimate social networks and sexual networks on HIV-infection in men aged ≥ 50 years in Pengzhou, Sichuan Province, and provide reference for the formulation of HIV/AIDS prevention and control strategies in middle-aged and elderly people. Methods A case-control study was conducted by an interview-style questionnaire survey in a case group consisted of 114 men aged ≥ 50 years and a control group consisted of 423 healthy men matched by age frequency in Pengzhou, Sichuan Province, from April 2019 to October 2020, and the influencing factors of HIV infection were identified by unconditional stepwise logistic regression analysis. Results Among the 114 cases, 63.16% (72/114) and 96.49% (110/114) of men had intimate social network size and sexual network size ≥ 4 people, which were higher than the control group of 23.40% (99/423) and 11.58% (49/423) (all P<0.05).The overlap of intimate social network and sexual network was 49.12% (56/114) in the case group, which was lower than that in the control group (82.27%, 348/423)(P<0.05). Logistic regression analysis showed that the size of the intimate social network ≥ 4 people (OR=8.66, 95%CI:2.01-37.30), the size of the sexual network ≥ 4 people (OR=1 121.11, 95%CI:28.38-4 429.61), the material support from the first intimate network member (OR=6.39, 95%CI:1.03-39.75), and multiple sexual partners (OR=55.50, 95%CI:6.22-494.96) were the risk factors of HIV-infection in men aged ≥ 50 years. Receiving health education about AIDS (OR=0.07, 95%CI:0.01-0.37), high sexual satisfaction with the first sexual partner and good personal relationship (OR=0.02, 95%CI:0.01-0.59; OR=0.01, 95%CI:0.01-0.26), and the overlap between intimate social network and sexual network (OR=0.02, 95%CI:0.01-0.38) were the protective factors of HIV-infection in men aged ≥ 50 years. Conclusions The overlap of intimate social network and sexual network can reduce the risk of HIV-infection in men aged ≥ 50 years. It is important to help middle-aged and elderly men to build good and stable intimate social and sexual networks to meet their social communication and sex demands and prevent HIV infection by reducing high riak sexual behaviors.
