中文摘要: 目的 了解广州市男男性行为者(men who have sex with men，MSM)的安全套使用情况及相关影响因素，为针对性开展MSM人群干预工作提供依据。方法 2015—2016年对目标人群进行面对面问卷调查、艾滋病和梅毒血清学检测。结果 1 036名MSM的HIV抗体和梅毒阳性检出率分别为7.24%、4.83%。80.60%的MSM最近六个月发生过肛交性行为，8.78% MSM与异性发生过性行为。最近一次发生同性肛交性行为时安全套使用率从2015年的71.75%上升到2016年的81.49%(P＜0.05)；最近六个月发生同性肛交性行为时每次均用安全套比例从2015年的53.81%上升到2016年的65.04%(P＜0.05)；最近一次发生异性性行为时安全套使用率从2015年的47.83%上升到2016年的66.67%(P＞0.05)；最近六个月发生异性性行为时每次均用安全套比例从2015年的26.09%上升到2016年的60.00%( P＜0.05)。多因素分析结果显示，文化程度高(OR=1.594，95%CI：1.100～2.308)、最近一年接受过干预服务(OR=1.521，95%CI：1.105～2.093)的MSM更容易坚持使用安全套,最近一年曾被诊断患过性病(OR=0.334，95% CI：0.149～0.745)的MSM坚持每次使用安全套比例低。结论 广州市MSM人群安全套使用率低、知行分离，艾滋病、梅毒感染率高，应采取更为有效的综合干预手段，促使MSM人群减少不安全性行为，提高安全套使用率，遏制艾滋病的进一步传播蔓延。
Abstract:Objective To understand the status of condom use and its influencing factors among 1 036 men who have sex with men (MSM) in Guangzhou, and to provide scientific evidence for prevention and control of AIDS in MSM. Methods The information about HIV/AIDS among MSM were collected with a face-to-face questionnaire interview by trained investigators in 2015-2016. Serological tests for HIV and syphilis were performed after questionnaire. Results HIV and syphilis infection rates in 1036 MSM were 7.24% and 4.83%,respectively. During the previous six months, 80.60% of the MSM had anal sex with men and 8.78% of them had sex with females. Condom use rates of MSM the latest homosexual anal sex were increased from71.75% in 2015 up to 81.49% in 2016(P＜0.05). Condom use rates of MSM nearly six months homosexual anal sex were increased from 53.81% in 2015 up to 65.04% in 2016(P＜0.05). Condom use rates of MSM the latest heterosexual sex were increased from 47.83% in 2015 up to 66.67% in 2016 (P＞0.05).Condom use rates of MSM nearly six months heterosexual sex were increased from 26.09% in 2015 up to 60.00% in 2016（P<0.05).Multivariate logistic regression analysis showed that the protective factors for condom use were high educational level（OR=1.594，95% CI：1.100～2.308）, receiving intervention services（OR=1.521，95% CI：1.105～2.093）in the last year, while those reporting venereal disease in the last year were opposite. Conclusion The MSM in Guangzhou, the rate of condom use was low, the knowing-doing gap was big, and the infection of HIV and syphilis were relatively high, effective interventions should be strengthened, unsafe sexual behavior should be reduced, condom use rates of MSM should be increased, to control the spread of HIV.
