目的了解安徽省男男行为者(MSM)的艾滋病病毒(HIV)感染情况,分析其可能的相关影响因素。方法通过《艾滋病综合防治数据信息管理系统》平台,导出2014年MSM国家级监测点数据,经整理核对和逻辑检验后,采用χ2检验和多因素Logistic回归进行统计分析。结果 1601名MSM中,检测出HIV抗体阳性127例,阳性检出率为7.9%。多因素Logistic回归分析结果:文化程度高中或中专比初中及以下[比值比(OR)=0.344,P<0.001;大专及以上比初中及以下OR=0.325,P<0.001];在当地居住时间>1年且≤2年与≤1年比,OR=0.384,P=0.006;最近1次同性肛交时使用安全套比未使用安全套OR=0.549,P=0.005。。结论安徽省MSM中的艾滋病感染风险目前已处于较高水平,今后行为干预工作的重点和难点是文化程度较低、频繁往来于高HIV感染风险地区的MSM,而安全套推广使用工作仍需进一步加强。
Objective To understand the HIV infection among men who have sex with men (MSM) in Anhui province and analyze its possible related factors. Methods The data of MSM national monitoring points in 2014 were derived from the platform of “Integrated AIDS Prevention and Control Data Information Management System”. After collation and logic tests, the data were analyzed by χ2 test and multivariate logistic regression. Results Of 1601 MSMs, 127 were detected positive for HIV antibody, the positive rate was 7.9%. Multivariate Logistic regression analysis showed that the educational level of high school or secondary school was lower than that of junior high school [OR = 0.344, P <0.001; OR = 0.325, junior high school and above, P <0.001] OR = 0.384, P = 0.006 for> 1 year and ≤2 years vs ≤1 year; OR = 0.549, P = 0.005 for condom use for same-sex anal sex vs unused condom. . Conclusions The risk of HIV infection in MSM in Anhui Province is at a high level at present. The focus and difficulty of behavioral intervention in future will be MSM with low educational level and frequent contact with high HIV infection risk areas, and the promotion and use of condoms need to be further strengthened .
