卫生九项目部分省吸毒人群艾滋病行为监测调查结果分析

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。
