【摘要】：目的了解中山市2012-2014年男男性行为者(MSM)艾滋病流行的特点及变化,为制定相关防控策略提供依据。方法利用"艾滋病综合防治信息系统"中病例报告模块下载的历史卡片,对2012-2014年经同性性行为传播的艾滋病(AIDS)病例进行分析;通过MSM哨点监测,分析人口学、行为学、血清学等流行特点;1型艾滋病病毒(HIV-1)新发感染率采用BED-CEIA方法进行估算。结果 2012-2014年,中山市"艾滋病综合防治信息系统"病例报告中,经同性性传播的病例230例,其中21.3%(49例)自我报告有过异性性伴侣,人均异性性伴数为3.0人;83.0%(191例)自我报告有过2个以上同性性伴侣,人均同性性伴侣数为6.4人。MSM哨点监测共调查MSM 816人,其中26岁及以上者占60.0%(490人),高中及以上文化程度为71.1%(580人),未婚或离异/丧偶者占74.0%(604人)。2012-2014年,MSM HIV抗体阳性率为13.4%(109/816)。单因素分析表明,文化程度和本地居住时间是HIV感染的影响因素(均P0.01)。MSM最近半年发生肛交的比例从83.6%(234/280)增加至94.4%(237/251),最近一次商业性行为使用安全套的比例从62.5%(10/16)上升至100.0%(13/13)(均P0.05);估算HIV-1新发感染率从9.6%降至3.1%(线性趋势R~2=0.985);梅毒感染率从17.9%(50/280)降至8.0%(20/251)(趋势χ~2=12.686,P0.001)。结论中山市MSM防控措施初见成效,但仍有流行风险,需继续加强防控;存在知识行为分离现象,有待进一步调查弄清原因。
[Abstract]:Objective to understand the characteristics and changes of HIV / AIDS prevalence in MSMMSM in Zhongshan City from 2012 to 2014, and to provide the basis for making relevant prevention and control strategies. Methods the history card downloaded from the case report module of the Integrated AIDS Prevention and Control Information system was used. An analysis of HIV / AIDS cases transmitted by same-sex sex between 2012 and 2014 was carried out; demographic and behavioural studies were analyzed through MSM sentinel surveillance. BED-CEIA method was used to estimate the new infection rate. Results in the "Integrated AIDS Prevention and treatment Information system" case report in Zhongshan City from 2012 to 2014, 230 cases of same-sex transmission were reported. Among them, there were 49 self-reported heterosexual partners, and the average number of heterosexual partners per capita was 3.00.There were more than 2 same-sex partners reported by self-report, and the number of same-sex partners per capita was 6.4. MSM sentinel surveillance investigated 816 persons. Of these, 60.0490 were aged 26 and above, 580 were educated at high school and above, and 74.0 were unmarried or divorced / widowed. The positive rate of anti-MSM HIV antibody in 2012-2014 was 13.440 / 109 / 8160.The results of univariate analysis showed that. Education level and local residence time were the influencing factors of HIV infection (P0.01. MSM had anal sex from 83.6% / 280% in the last half year) to 94.4% 237 / 251%, and the last commercial sex condom use rate rose from 62.5% 10 / 16 to 100.013% 13% (all P0.05; estimate HIV-1 new development). The infection rate decreased from 9.6% to 3.1 (the linear trend is 0.985N; the syphilis infection rate decreased from 17.90.50 / 280) to 8.0% 20 / 2510.Conclusion the prevention and control measures of MSM in Zhongshan City are effective. But there are still epidemic risks, need to continue to strengthen prevention and control, there is a phenomenon of separation of knowledge and behavior, need to be further investigated to find out the reasons.
