Abstract
目的 分析2018年北京市吸毒人群艾滋病病毒(human immunodeficiency virus,HIV)、丙型肝炎(hepatitis C virus,HCV)感染状况和危险因素.方法 2018年4—8月采用国家艾滋病哨点监测问卷对吸毒人群进行横断面调查,采集调查对象血液标本进行HIV和HCV抗体检测.结果 共监测吸毒者2887人.HIV阳性率为1.2%,HCV阳性率为16.9%.吸毒者中73.6%吸食冰毒,23.2%吸食海洛因.22.2%注射吸毒;2.0%发生过肛交行为.吸毒者感染HIV的危险因素为肛交(OR=50.090,95%CI:3.928~68.817).感染HCV的危险因素为户籍(OR=2.429,95%CI:1.061~5.565)、吸食海洛因(OR=3.447,95%CI:1.305~9.107)、曾经共用注射器(OR=5.019,95%CI:1.804~13.966)和最近一年HIV检测(OR=2.593,95%CI:1.157~5.807).结论 北京市吸毒人群存在毒性交织的危险行为,传统毒品的注射行为和吸食新型毒品后高风险的性行为预示可能发生更高的HIV流行.
