目的：了解东莞市吸毒人员HIV、梅毒的感染状况，为干预措施的制定提供理论数据。方法：对吸毒人员吸毒方式、性行为等进行问卷调查，并采血样检测HIV抗体、梅毒抗体。结果：395名吸毒者中，HIV、梅毒感染率分别为6．84％和9．62％。单一口吸者、口吸并静注者、单一静注者HIV感染率分别为0％、8．14％、23．08％；梅毒感染率分别为10．81％、9．30％、7．69％；这3种吸毒方式之间HIV感染率有显著性差异，单一静注者感染率最高。有静脉注射史者（包括单一静注者和口吸并静注者）占71．9％（284／395），其中共用针具者与非共用针具者HIV感染率分别为18．42％（21／114）、3．53％（6／170），两者相比有显著性差异；非共用针具静注者与单一口吸者之间HIV感染率并无显著性差异。以上各组间梅毒感染率无显著性差异。本次调查中吸毒者不同性行为（有无用安全套）之间HIV、梅毒的感染率无显著性差异。结论：本市吸毒人群HIV的感染率处于中等水平，共用注射器吸毒是HIV感染的主要因素。有必要在吸毒人群中开展艾滋病知识的宣传和干预。
