Objective To examine general characteristics of human immunodeficiency virus (HIV)-positive men who have sex with men (MSM) in Guangxi Zhuang Autonomous Region (Guangxi) and influencing factors of mortality among the MSM for providing evidences to develop AIDS prevention and control strategies.
Methods We collected information on all male HIV/AIDS cases infected via homosexual pathway and reported in Guangxi from 2005 till 31 December 2017 from National Information Management System for Comprehensive AIDS Prevention and Control in China. Descriptive epidemiology and logistic regression analysis were adopted to analyze general characteristics and mortality-related factors of the HIV-positive MSM.
Results Of the 3 058 MSM included in the study, 76.3% were less than 40 years old; 67.1% were with the education of senior high school or technical secondary school and above; 52.7% reported having three or more homosexual sex partners; and 42% reported having three or more unmarried sex partners. Multivariate logistic regression analysis revealed that education level, the number of homosexual sex partners, receiving antiretroviral therapy (ART) and undergoing HIV testing previously were independent factors of mortality among the HIV-positive MSM.
Conclusion Highrisk behaviors are prevalent among the HIV-positive MSM in Guangxi, suggesting that health education on AIDS/HIV prevention and HIV testing should be promote among the population to control HIV infection and to reduce the fatality of AIDS.
【摘 要】 目的 了解广西壮族自治区艾滋病病毒（HIV）抗体阳性男男性行为人群（MSM）人群的基本特征，并分析影响其死亡的因素, 为制定相关艾滋病防治政策提供科学依据。 方法 收集 2005 — 2017 年 12 月 31 日广西壮族自治区累计报告感染 HIV 途径为同性传播的 3058 例确诊病例，对其行为特征及影响其死亡的因素进行描述性和 logistic 回归分析。 结果 共有 3058 例病例符合纳入标准，年龄 < 40 岁为主，占 76.3 %，文化程度以高中或中专及以上为主，占 67.1 %；同性性伴数 ≥ 3 个占 52.7 %，非婚性行为性伴数 ≥ 3 个占 42.0 %；多因素分析表明，患者的文化程度、同性性伴个数、接受抗病毒治疗和既往接受 HIV 检测是 HIV 阳性 MSM 死亡的影响因素。 结论 广西壮族自治区感染 HIV 的 MSM 者普遍存在高危行为接触史，应加强对该人群开展宣传教育活动，有效开展 HIV 检测，早发现早治疗，以阻断艾滋病的传播，减少病死率。
