This study aimed to estimate human immunodeficiency virus （HIV） co-infection with hepatitis C and B viruses （HCV and HBV） and their risk factors in a rural area of Shanxi Province with a history of commercial blood donation. Methods： A cross-sectional study was conducted in 2004. All adult residents in the target area were invited to participate in the study. Face-to-face interviews were completed and blood specimens were tested for HIV, HCV, and HBV surface antigen （HBsAg）. Results： Prevalence rates of HIV, HCV, and HBsAg were 1.3% （40/3 062）, 12.7% （389/3 062）, and 3.5% （103/2982）, respectively. Of the 40 HIV-positive specimens, 85% were HCV positive and 2.5% were HBsAg positive. The history of commercial blood donation was positively associated with HIV, HCV, and HIV/HCV co-infections, but was negatively associated with HBsAg seropositivity. Migration for employment in the last 5 years was positively related to HIV, HBsAg, and HIV/HCV co-infections. Univariate logistic analysis showed that illegal drug use, number of sex partners, extramarital sex behavior, commercial sex behavior, and condom use rate were not related to anti-HIV, anti-HCV, HBsAg seropositivity or their co-infections. Conclusion： The history of commercial blood donation was the main risk factor for HIV, HCV, and HIV/HCV co-infections in this former commercial blood donation area. HIV and HCV prevention and treatment interventions are important in this area.展开更多
