目的了解社区吸毒者艾滋病、丙肝、梅毒的感染率及高危行为特征。方法由禁毒社工采用统一问卷进行调查,并由医务人员采集血样进行血清学检测。结果121名社区吸毒者中未检出HIV感染者,梅毒RPR阳性1例,乙肝表面抗原阳性7例,丙肝抗体阳性43例。多元Logistic回归分析显示:不同文化程度、籍贯、静脉吸毒情况的吸毒者丙肝感染率差异具有统计学意义,文化程度低、外省市、曾有静脉吸毒行为者感染率较高。54.5%有静脉吸毒行为,其中22.7%在最近一次静脉吸毒中共用注射器,外省市静脉吸毒率高于本市。结论社区吸毒者静脉吸毒率高,丙肝感染率高,应加强社区吸毒者艾滋病健康教育和行为干预工作。
Objective To understand the prevalence of HIV / AIDS, hepatitis C and syphilis among community drug users and the characteristics of high-risk behaviors. Methods An anti-drug social worker conducted a survey using a unified questionnaire, and blood samples were collected by medical staff for serological testing. Results Among the 121 community drug users who did not find HIV infection, 1 was RPR positive for syphilis, 7 were positive for hepatitis B surface antigen and 43 were hepatitis C antibody positive. Multivariate logistic regression analysis showed that there were significant differences in hepatitis C infection among drug abusers with different educational level, native place and intravenous drug use. The educational level was lower in other provinces and cities. There was a higher prevalence of drug abuse in other provinces and cities. 54.5% had intravenous drug use behaviors, of which 22.7% shared syringes in the most recent intravenous drug use, and the rate of intravenous drug use in other provinces and cities was higher than that in other cities. Conclusion Community drug addicts have a high rate of intravenous drug use and a high rate of hepatitis C infection. HIV / AIDS health education and behavioral intervention among community drug addicts should be strengthened.
