A generalized estimated equation (GEE) logistic regression model was used to identify the determinants of HCV infection among HD patients.Results: The prevalence of anti-HCV or HCV-RNA infection among HD patients was 1.77% or 1.42% respectively. GEE model showed that history of kidney transplantation (HCV-RNA: OR=19.79, 95%CI: 12.69– 30.85) could dramatically increase the risk of current HCV infection in dialysis patients. Compared with never using of blood products, using of blood products (anti-HCV: OR=2.38, 95%CI: 1.22– 4.64; HCV-RNA: OR=15.23, 95%CI: 1.79– 129.49) could increase the risk of HCV infection in dialysis patients. Moreover, with the increase of HD duration, the risk increased one time or so (anti-HCV: OR=1.83, 95%CI: 1.22– 2.72; HCV-RNA: OR=2.00, 95%CI: 1.11– 3.61). Furthermore, dialysis in multiple hospitals possessed more than three times risk of HCV infection (anti-HCV: OR=3.56, 95%CI: 3.11– 4.08; HCV-RNA: OR=3.35, 95%CI: 1.88– 5.96). Besides, HD patients having the history of acupuncture (HCV-RNA: OR=5.56; 95%CI: 1.16– 26.67) or surgery (HCV-RNA: OR=6.39; 95%CI: 2.86– 14.29) caused an about-six-times risk of current infections.Conclusion: It could be concluded that the prevalence of HCV infection was mild and using of blood products or kidney transplantation, long dialysis duration, dialysis in multiple hospitals, surgery or acupuncture treatment were some risk factors of HCV infection among HD patients in Lanzhou of Northwestern China.Keywords: hemodialysis, hepatitis C virus, generalized estimating equation introduction
