绵阳市县级MSM艾滋病知识知晓及预防服务覆盖促进效果分析

Analysis on promoting effects of AIDS knowledge and preventive service coverage among MSM in Mianyang City

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 change trend of awareness status of AIDS knowledge and preventive service coverage Mianyartgamong men who have sex with men （MSM） of Mianyang City at county-level, evaluate the promoting effects. [Methods]MSM were collected from 9 counties/cities/districts of Mianyang City by the snowball sampling. With the informed consent, a self-administered anonymous ethology survey was performed with the same questionnaire in the baseline period, interim period and terminal period. The changes of awareness status of AIDS knowledge and preventive service coverage were compared. [Results] There were 820, 833 and 861 qualified respondents in the baseline period, interim period and terminal period respectively, with the consistent demographic characteristics （all P〉0.05）. The average awareness rate of AIDS knowledge was 97.2%, and there was no statistically significant difference among different periods （P〉0.05）. However, the differences in the awareness rates of HIV cannot be spread through having dinner with HIV/AIDS patients, HIV can be spread through blood transfusion, HIV can be spread through sharing needles with HIV/AIDS patients, and fixed sexual partners can decrease the transmission risk were statistically significant among different periods （all P〈0.01）. The proportion of respondents have received the peer education in recent 1 year showed a rising trend, and the proportions of respondents have received the condom promotion and distribution, and HIV counseling and testing showed a downward trend （all P〈0.01）. The rate of self-reported STD in recent 1 year showed a downward trend （P〈0.05）.[Conelusion] The county-level HIV/AIDS prevention and control system for MSM runs well in Mianyang City, the awareness rate of AIDS knowledge reaches higher level, the preventive service coverage has been extended, and STD infection has been basically controlled. However, the situation has fluctuated, so the measures should be further strengthened.
