目的:了解宁波地区海洛因依赖者丙型肝炎病毒(HCV)感染情况及其影响因素。方法:于2007年6月―9月对宁波地区114例海洛因依赖者进行问卷调查,调查内容包括社会人口学、毒品使用、共用注射器静脉吸毒以及安全套使用情况等,同时采集血样进行HCV抗体检测。结果:在114例海洛因依赖者中,HCV感染率为71.1%。HCV感染与年龄、吸毒时间、吸毒方式及共用注射器有关。年龄在28岁以下的感染率为78.1%,吸毒时间在5年以上的感染率为81.8%,静脉注射吸毒的感染率为77.8%,共用注射器吸毒的感染率为87.7%。结论:近年来,宁波地区海洛因依赖者HCV感染率显著上升,应该在该地区进一步加大干预工作的力度以控制HCV的传播。
