目的了解卫生九项目部分地区吸毒人群的艾滋病相关认知、态度和行为状况及其变化趋势,为制定有效干预措施和评估项目实施效果提供依据。方法以各轮调查的前一轮调查所获的共用针具比例,计算本轮监测调查样本量,采用“滚雪球(Snowball Sampling)”等非随机抽样方法,对吸毒者进行面对面匿名问卷调查。结果三轮行为监测调查结果显示:吸毒人群的艾滋病相关知识知晓率总体呈上升趋势(69.6%到95.1%);对艾滋病持正确态度的比例明显提高;共针率有所下降(65.6%到25.3%);安全套使用率有所提高。结论项目地区针对吸毒人群开展的干预工作成效显著,但仍需进一步有针对性地开展艾滋病防治宣传教育,深入持久地开展以减少毒品危害措施为主的综合干预活动,扩大针对吸毒人群的干预覆盖面,从而有效控制艾滋病疫情的进一步蔓延。
Objectives To understand AIDS-related cognitive, attitudinal and behavioral changes and their trends of drug abusers in some areas of J9 project, and provide the basis for formulating effective interventions and assessing the effect of project implementation. Methods Based on the proportion of common needles obtained in the previous round of rounds of surveys, the sample size of the current round of surveillance surveys was calculated and a non-random sampling method such as Snowball Sampling was used to conduct face-to-face anonymous questionnaires among drug users . Results The results of three rounds of behavioral surveillance showed that the awareness rate of AIDS-related knowledge among drug users was generally on the rise (69.6% to 95.1%); the proportion of people with a correct attitude towards AIDS was significantly increased; the rate of common needles decreased (65.6% to 25.3 %); Condom use rate has increased. Conclusion The interventions for drug addicts in the project area have achieved remarkable results. However, there is still a need to conduct more targeted publicity and education on HIV / AIDS prevention and control, deepen the long-term comprehensive intervention to reduce drug-related harm, and increase the coverage of drug abusers , So as to effectively control the further spread of the AIDS epidemic.
