Abstract：Objective To investigate the infection rate of hepatitis B among unpaid blood donors in Zhengzhou City, and to provide a scientific basis for hepatitis B prevention and control. Methods HBV gold test strip was used to initially screen 661,184 unpaid blood donors, and then a classified statistics was made according to the frequency of blood donation, types, ages, genders, occupations and education levels. Results The infection rates of hepatitis B virus in blood donors who donated whole blood for the first time and those who donated apheresis platelets were 1.044% and 1.894%, respectively, showing a statistically significant difference (χ2=97.795, P<0.001). Among the first-time blood donors, the infection rate of hepatitis B virus was significantly higher in males than in females (1.334% vs. 0.687%, χ2=314.594, P<0.001). No statistically significant difference was found in the infection rate of hepatitis B virus between the male and female repeated blood donors (χ2=0.010, P>0.05). The infection rate of hepatitis B virus in the first-time blood donors increased with the increasing age, and it was lower in males and females aged 18-25 years, but significantly higher in males aged 26-35 years. The infection rate of hepatitis B virus in the repeated blood donors had changed a little bit with the increasing age. Among the first-time blood donors, the infection rate of hepatitis B virus was found to be higher in traders, farmers, workers, freelancers and service personnel, but lower in doctors, civil servants and soldiers. The infection rate of hepatitis B virus in the repeated blood donors was low and had changed a little bit. The infection rates of hepatitis B virus in the first-time and the repeated blood donors decreased with the increase of education level. Conclusion The hepatitis B infection rate of the unpaid blood donors in Zhengzhou City was low, and the infection rate was found to be higher in males aged 26-35 years, farmers and donors with technical secondary school education and below. It is necessary to enhance the propaganda about knowledge related to hepatitis B prevention and treatment when we strengthen the immunization against hepatitis B virus infection.
