摘要
目的了解广州市男男性接触者(MSM)的HIV和现症梅毒感染情况及其影响因素。方法于2008年10—12月采用分类滚雪球抽样法,对在酒吧、浴池、公园和网络等场所招募到的MSM进行面对面问卷调查及采集5 mL静脉血做HIV、梅毒血清学检测。问卷内容包括调查对象的人口学特征、艾滋病相关知识知晓情况、艾滋病干预覆盖情况、性行为相关信息、有无使用违禁药品、有无性病相关症状及其处理方式等,并将人群人口学特征、艾滋病相关知识知晓、干预措施覆盖及性行为相关信息等16个因素与HIV感染/现症梅毒感染分别进行单因素和多因素logistic回归分析。结果共调查452名MSM,其HIV和现症梅毒感染率分别为4.9%和6.0%;自认为同性恋和双性恋的MSM分别占63.9%和27.0%;艾滋病知识知晓率为95.1%,70.1%接受过相关的预防艾滋病干预服务,24.3%的人近1年内做过HIV检测。90.3%近6个月内有男男同性肛交性行为,其中66.2%的MSM在近6个月发生过无保护肛交性行为,67.6%近6个月内有2个及以上的男性性伴。多因素logistic回归分析结果显示,外省户籍(OR=5.4)和现症梅毒感染(OR=3.9)是HIV感染的相关影响因素;外省户籍(OR=7.0)、近1年内有性病相关症状(OR=2.9)及HIV感染(OR=4.1)是现症梅毒感染的相关影响因素。结论广州市MSM人群的HIV和现症梅毒感染率已处于较高水平,应重点加强流动MSM人群综合干预和扩大MSM人群性病诊疗覆盖面,以控制HIV和梅毒在广州MSM人群中的蔓延。
Objective To examine the prevalence of HIV and current syphilis and associate factors among men who have sex with men （ MSM ） in Guangzhou. Methods Participants were recruited from bars, baths, parks and network using snowball sampling in Guangzhou from October to December 2008. Each participant was provided an anonymous face-to-face questionnaire interview and HIV and syphilis antibody tests.

Results Among 452 participants interviewed, the prevalence of HIV and current syphilis were 4. 9% and 6. 0% respectively. 63.9% of subjects self - identified themselves as homosexual, 27.0% as bisexual. 95.1% were aware of AIDS-related knowledge, 70. 1% have accepted HIV prevention interventions, 24. 3% of MSM received an HIV test in the past 12 months, 90. 3% had anal sex in the past 6 months, of whom, there were 66. 2% had unprotected anal sex in the past 6 months, 67.6% had 2 or more sex partners in the past 6 months. Multivariate analysis suggested that household register status （ OR = 5.4） and current syphilis infection （ OR = 3.9 ） were associated independently with HIV infection. Household register status （OR =7. 0）, self-reported sexually transmitted infection （STI） symptoms in the past 12 months （OR =2. 9） and HIV infection （OR =4. 1 ） were associated independently with current syphilis infection.
