为了探讨注射吸毒人群丙型肝炎病毒(HCV)感染的影响因素,以2006~2008年江苏省5市部分戒毒所、劳教所新入的1 358例注射吸毒人员为调查对象。对调查对象进行问卷调查,采血并对血液标本行ELISA法检测抗-HCV,数据用SPSS13.0行单因素和多因素分析。1 358例注射吸毒者中共检测出HCV抗体阳性者798例,阳性率为58.8%;男性注射吸毒者易感染HCV(χ2=8.30,P<0.05);随着年龄的增长HCV的感染率呈下降趋势(χ2=11.87,P<0.05);共用注射器、注射吸毒时间大于10年、商业性性行为是该人群HCV感染的危险因素。注射吸毒人群中HCV感染率远高于一般人群,说明该人群是HCV防治重点人群。因此,对该人群HCV感染的危险因素需进行针对的健康教育和行为干预综合防治措施。
In order to investigate the influencing factors of hepatitis C virus (HCV) infection in injecting drug users, we included 1 358 injecting drug addicts who were newly admitted by reeducation-through-labor camps in 5 cities of Jiangsu Province from 2006 to 2008 and re-education through labor camps. Questionnaires were collected from the survey subjects, blood samples were taken and anti-HCV was detected by ELISA in blood samples. The data were analyzed by SPSS13.0 single factor and multivariate analysis. In the 358 cases of injecting drug users, 798 cases were detected positive for HCV antibody, the positive rate was 58.8%. The male drug addicts were predisposed to HCV (χ2 = 8.30, P <0.05); the infection rate of HCV decreased with the increase of age Trend (χ2 = 11.87, P <0.05); sharing syringes, injecting drugs for more than 10 years, commercial sexual behavior is the risk factor for HCV infection in this population. HCV infection among injecting drug users is much higher than that of the general population, indicating that this population is a key population of HCV prevention and treatment. Therefore, the risk factors for HCV infection in this population need to be targeted health education and behavioral interventions comprehensive prevention and control measures.
