Investigation of HIV related knowledge,behaviors and infection status among men who have sex with men in Nanning city

目的了解南宁市男男性行为人群(MSM)艾滋病知识知晓、行为及艾滋病感染状况,为针对性开展MSM人群艾滋病防治工作提供依据。方法采用流行病学调查与血清学检测相结合的方法,于2010—2013年对该人群进行问卷调查,并采集血液进行HIV检测。使用Epi Data3.0建立数据库,SPSS13.0软件进行数据统计分析。结果 2010—2013年南宁市共1 819名MSM接受调查检测,该人群艾滋病知识知晓率主要与年龄、文化程度和是否接受过干预等因素有关。单因素分析表明最近6个月同性肛交安全套使用率与年龄、婚姻状况、文化程度、艾滋病知识得分、近一年是否接受过干预有关(P<0.05或P<0.01),而多因素分析表明其与文化程度和近一年是否接受过干预有关(P<0.05)。最近6个月同性性行为中安全套使用率不同,艾滋病感染率也不同(P<0.05)。结论 MSM安全套使用情况与艾滋病感染风险密切相关,且影响因素复杂,需要增加有针对性地干预力度,有效提高安全套率。

Objective To understand the HIV related knowledge ,behavior and infection status among men who have sex with men （MSM）, and to provide scientific evidence for prevention and control of AIDS in MSM. Methods Four consecutive surveys were conducted among MSM in 2010, 2011, 2012, and 2013 respectively. Blood samples were collected from all participants for HIV detection. Survey data were recorded with Epi Data 3.0 software and statistically analyzed with SPSS 13.0 software. Results A total of 1 819 participants were investigated during 2010-2013. The awareness rate of AIDS-related knowledge was related to age, education level and history of receiving AIDS interventions in the past year. Univariate analysis showed that the frequency of condom use when having anal sex in the last 6 months was associated with age, marital status, education level, awareness of AIDS knowledge and history of receiving AIDS interventions in the past year （P〈0.05 or P〈 0.01）. However, multivariate analysis showed that the awareness rate was associated with education level and history of receiving AIDS interventions in the past year （P〈0.05）. The rate of HIV infection among the MSM was affected by the frequency of condoms use in the last 6 months （P〈0.05）. Conclusion The frequency of condom use is significantly related to HIV infection and the influencing factors are complex. It is necessary to strengthen the intervention and promote the condom use.
