目的了解玉林市吸毒人群HIV流行趋势及其行为变化,为制定艾滋病防治对策提供依据。方法采用描述流行病学方法对2001-2009年玉林市吸毒人群艾滋病哨点监测资料进行分析。结果2001-2009年玉林市共调查吸毒人员5032名,HIV年均感染率为2.98%,HIV感染率从2001年的7.19%下降到2009年的1.81%。吸毒人群中注射吸毒比例波动在74.69%～86.04%之间,共用注射器的比例从2001年的82.85%下降到2009年的34.16%,性乱的比例由2001年的68.13%下降到2009年的37.77%,从未使用安全套人数的比例从2001年的76.15%下降到2009年的43.91%。结论玉林市吸毒人群HIV感染率低且呈下降趋势,说明我们过去采取的干预措施有效,但是玉林市吸毒人群中注射吸毒现象仍然严重,共用注射器、性乱等不良现象依然存在,安全套使用率还很低,控制艾滋病在吸毒人群中传播还是我们今后艾滋病防控工作的重点。
