Aim: This study aimed to determinate the prevalence and risk characteristics of hepatitis B virus (HBV) infection in adult population. Methods: A total of 409,488 participators were recruited and multivariate regression analysis was used to determinate the risk factors of present and past HBV infections. Results: The present and past HBV infection rate was 8.0% (32,601/409,488) and 11.0% (41,409/376,887) respectively. Main risk characteristics of current infection were HBV family history, marital status, male gender, vaccination status, BMI and lower education levels (all p < 0.05); and main risk characteristics of past infection were marital status, HBV family history, surgery/blood transfusion history, male gender, lower BMI and lower education levels (all p < 0.05). Conclusion: The prevalence of HBV infection is relatively higher in this region and risk characteristics were similar between present and past HBV infections.
