2010-2012年新会区吸毒人群艾滋病监测结果分析

目的了解新会区吸毒人群艾滋病病毒（HIV）的感染情况及其相关危险因素，为制定针对吸毒人群艾滋病防控措施提供参考依据。方法对2010-2012年在新会区强制戒毒的3443名吸毒人员采用统一的监测问卷进行流行病学调查，并进行HIV抗体检测。结果共调查3443名吸毒者，共检出HIV抗体阳性者63名。吸毒年龄（32.25±6.52）岁，以25～59岁年龄段为主，占65.76％，本地户籍占66.66％。吸毒方式以口吸为主，占71.54％，近几年共用注射器率呈现逐年下降的趋势。吸毒人群的商业性性行为发生率有上升趋势（x^2=79．58，P〈0.05）。发生商业性性行为时每次使用安全套的比例呈现逐年下降的趋势（x^2=16.52，P〈0．05）。结论新会区吸毒人群HIV感染率总体处于低流行水平，但仍存在艾滋病传播的相关危险行为，新型毒品流行迅速，需引起更多关注，对此类人群应采取有效的综合干预措施，以遏制艾滋病在此类人群中传播。
