Abstract：Objective To investigate and analyze the prevalence of HCV infection and its risk factors among drug users in Changde City. Methods The objects were recruited by cluster samlping method in 2010-2014. Demographic and behavioral information was obtained by an anonymous questionnaire survey. Multi-factor logistic regression model was used to analyze the risk factors of HCV infection. Results The HCV infection rate of the 2,000 drug users surveyed was 54.9%, with the HCV infection rate of 78.7% in the injected drug users. Multi-factor logistic regression analysis showed that intravenous drug abuse and sharing needles were closely associated with the HCV infection rate; moreover, the longer the time of injecting drug abuse and sharing needles, the higher the HCV infecton rate. Conclusions The infecton rate of HCV in drug users in Changde City shows an increasing tendency from 2010-2014. Intravenous drug abuse and sharing needles are the risk factors for HCV infection.
