以社区为基础的静脉吸毒人群共用注射器具行为特征研究

目的 了解凉山彝族自治州某地静脉吸毒人群共用注射器具的行为特征。方法 以社区为基础调查静脉吸毒人群人口学和共用注射器具吸毒行为情况。结果 在静脉吸毒的379人中，曾经共用注射器具的247人(65．2％)；近3个月使用别人用过的注射器具吸毒的166人(43．8％)。本人静脉注射转变到与他人共用注射器具吸毒的平均时间为363．73天，其中87人(35．2％)首次静脉注射吸毒即与他人共用注射器具。彝族吸毒人群从本人静脉吸毒转变到与他人共用注射器具吸毒的时间短，与他人共用注射器具吸毒的次数，以及近3个月使用别人用过的注射器具吸毒的次数，高于其他吸毒人群。低文化水平吸毒人群从本人静脉吸毒转变到与他人共用注射器具吸毒的时间短，与他人共用注射器具吸毒的次数，以及近3个月使用别人用过的注射器具吸毒的次数，高于其他吸毒人群。结论 针对彝族和低文化水平吸毒人群开展干预，以改变共用注射器具静脉吸毒的高危行为。

Community-based survey on sharing injection equipment among injection drug users
