目的了解绵阳市县级男男性行为者(MSM)艾滋病知识知晓、预防服务覆盖变化趋势,评价促进效果。方法以绵阳市辖区9个县(市、区)MSM为对象,在知情同意下,采用滚雪球抽样法,用相同问卷,分别进行基线、期中和终期的自填式匿名行为学调查,比较艾滋病知识知晓、预防服务覆盖变化。结果基线、期中、终期分别合格调查820、833和861例,人口学特征一致(均P>0.05)。艾滋病知识平均知晓率为97.2%,不同调查时间差异无统计学意义(P>0.05),但与人类免疫缺陷病毒(HIV)感染者/艾滋病患者共餐不会传染、输入HIV感染者/艾滋病患者血液会传染、与HIV感染者/艾滋病患者共用针具会传染、固定性伴可降低传播危险知晓率不同,差异有统计学意义(均P<0.01)。近1年接受过同伴教育呈上升趋势,接受过安全套宣传和发放/艾滋病咨询检测呈下降趋势(均P<0.01)。自报近1年患过性病呈下降趋势(P<0.05)。结论该市县级MSM艾滋病防治网络运行良好,艾滋病知识知晓率达较高水平,预防服务覆盖面提高,性病感染得到初步控制,但存在一定波动性,应进一步巩固加强。
Objective To understand the knowledge of HIV / AIDS and the trend of service coverage in MSM at county level in Mianyang and to evaluate the promotion effect. Methods The MSM of 9 counties (cities, districts) in Mianyang was used as the research object. With the informed consent, snowball sampling method was used to conduct baseline, mid-term and final self-signed anonymous behavioral surveys with the same questionnaire to compare HIV / AIDS Knowledge awareness, prevention of service coverage changes. Results There were 820, 833 and 861 cases, respectively, in the baseline, midterm, and final stages. The demographic characteristics were consistent (all P> 0.05). The average awareness rate of AIDS knowledge was 97.2%, but there was no significant difference between the two surveys (P> 0.05). However, the co-meal with HIV / AIDS patients would not be contagious and the patients infected with HIV / AIDS There was a significant difference between the two groups (P <0.01 for all), with blood transmitted, needle sharing with HIV / AIDS patients, and awareness of fixed partners reducing the risk of transmission. Peer education has been on the rise in the past year, and condom promotion and HIV / AIDS counseling and testing have been declining (all P <0.01). Since the report of nearly 1 year suffering from sexually transmitted diseases showed a downward trend (P <0.05). Conclusion The MSM HIV / AIDS prevention and control network at the county level is in good condition with a high awareness rate of AIDS knowledge, an improved coverage of preventive services and a preliminary control of STD infection. However, there is some volatility and it should be further consolidated and strengthened.
