柳州两县新报告男性HIV感染者经异性性传播影响因素分析

Analysis of influencing factors of heterosexual transmission of newly reported male HIV-infection cases in two counties of Liuzhou

目的 了解广西壮族自治区柳州市柳江县和鹿寨县新报告的通过异性性传播途径感染人类免疫缺陷病毒(Human immunodeficiency virus,HIV)男性病例的影响因素,为当地重点人群HIV感染防控干预提供科学指导。方法 选取2017—2018年柳州市柳江县和鹿寨县新报告的HIV感染病例开展对照研究,应用自行设计的调查问卷对相关人群开展调查,采用χ^(2)检验和logistic回归模型分析男性人群通过异性性途径感染HIV的影响因素。结果 共调查434人,病例组198人,对照组236人,病例组平均年龄(53.0±13.0)岁,艾滋病相关知识总体知晓率为62.7%(272/434)。多因素回归分析显示,文化水平低、有城镇生活、有外出打工史、不知晓艾滋病知识、近1年与暗娼/商业性性伴发生无保护性行为、偶尔或从未从家人/亲戚/朋友获得支持和帮助等因素是男性人群HIV感染的危险因素。结论 柳州市HIV男性感染者以中老年为主,此人群艾滋病知识知晓率低。外出务工男性人群HIV感染处于较高风险水平,相关卫生机构应加强该类人群随访,采取恰当的宣传方式进行干预。

Objective To understand the factors influencing the infection of HIV in the male population of newly-reported cases of Liujiang and Luzhai County of Liuzhou City in Guangxi Zhuang Autonomous Region through the heterosexual contact,so as to provide scientific guidance for prevention and control interventions for the essential populations.Methods A case-control study was conducted on newly reported cases of HIV-infection in Liujiang and Luzhai County from 2017 to 2018.A self-designed questionnaire was used to investigate the situation of relevant populations,and the χ^(2) text and logistic regression model were applied to analyze the influence factors of HIV infection through heterosexual contact.Results A total of 434 people were surveyed in the study,including 198 people in the case group and 236 people in the control group,with an average age of(53.0±13.0)years old in the case group.The AIDS-related awareness rate was 62.7%(272/434).Results from the multivariate logistic regression analysis showed that factors as:lower education level,living in urban areas,history of migrant work,lack of knowledge on AIDS,having unprotected sex with female prostitutes or commercial sex partners in the past year,occasionally or never getting support from family/relatives/friends were the risk factors for HIV infection in males.Conclusion The male HIV-infected patients in Liuzhou are mainly middle-aged and elderly people,and the awareness rate of AIDS among this population is low.Male migrant workers have a high risk of HIV infection.Relevant health institutions should strengthen the follow-up of this population and take appropriate publicity and intervention measures.
