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 knowledge, behavior and HIV status of HIV / AIDS among men who have sex with men (MSM) in Nanning, and to provide a basis for targeted HIV prevention and treatment in MSM population. Methods By means of a combination of epidemiological investigation and serological test, this population was surveyed from 2010 to 2013, and blood was collected for HIV testing. Use Epi Data3.0 to establish the database, SPSS13.0 software for data statistical analysis. Results A total of 1 819 MSM in Nanning from 2010 to 2013 were investigated. The awareness rate of AIDS among the population was mainly related to age, education level and whether they had received intervention or not. Univariate analysis showed that the condom use rate of same-sex anal intercourse in the recent 6 months was related to age, marital status, educational attainment, knowledge of HIV / AIDS and intervention in the past year (P <0.05 or P <0.01), while multivariate analysis With the degree of education and the past year has received intervention (P <0.05). Condom use rates in same-sex sexual behavior in the past 6 months were different, and HIV prevalence was also different (P <0.05). Conclusions The use of condom in MSM is closely related to the risk of HIV infection, and the influencing factors are complex. Therefore, it is necessary to increase the targeted intervention and improve the condom rate effectively.
