苏州市强制戒毒人群HIV梅毒HCV感染情况与相关行为调查

目的了解苏州市强制戒毒人群艾滋病病毒(HIV)、梅毒及丙型肝炎病毒(HCV)感染状况及相关因素,为在该人群中开展监测和行为干预提供依据。方法 2010年4月和7月,分两次对苏州市强制戒毒所内所有吸毒者进行调查。结果 460名强制戒毒人员的HIV感染率为0.43%(2/460),梅毒感染率为13.26%(61/460),HCV感染率为47.17%(217/460)。吸毒者中注射吸毒比例为44.13%(203/460),其中有过与别人共用注射器吸毒的比例为36.45%(74/203)。共用注射器吸毒人群HIV、HCV感染率与其他吸毒人群感染率有显著性差异。42.17%(194/460)的吸毒者有商业性行为,最近一次使用安全套的只有39.69%(77/460)。结论苏州市强制戒毒所内的吸毒者HIV感染率较低,但梅毒和HCV感染率较高,共用注射器吸毒是HIV和HCV感染的高危因素,不安全的性行为增加了HIV、梅毒等性传播疾病向一般人群传播的机会,应对吸毒人群开展有针对性的干预措施。
