The objective of this study was to determine the prevalence of serum HBsAg among adults in Henan province, China. A provincial serosurvey of people aged 18–74 years was conducted and individuals for analysis were selected using a multistage stratified random cluster sampling method. A 5-ml serum sample from each person was collected and the serum was tested for the presence of HBsAg, HBcAb, HBsAb, HBeAg, and HBeAb by ELISA. Multivariate analysis was used to identify factors associated with the prevalence of HBsAg. A total of 16,685 residents, aged 18–74 years who resided in 60 communities or villages in Henan, China were surveyed. Among the eligible study population, 642 HBsAg positive cases (3.7%) were found. The prevalence increased steadily from 3.1% among population aged 18–35 years old, to 5.1% among population aged 55–74 years. Accordingly, HBsAb declined steadily from 53.4% to 24.7%. Six hundred and forty-two positive HBsAg blood samples were screened for the HBeAg and HBeAb. HBeAg prevalence declined steadily from 27.7% among population age 18–35 years old to 6.8% among population age 55–74 years old. The single factor analysis was used for 16 possible risk factors and multivariate analysis showed that five risk factors were significantly related to HBV infection. HBV infection is a serious public health problem among adult population in Henan. Strengthening administrative regulations of medical practices, especially in rural areas, and providing health education propaganda to the public of HBV infection should be given more attention on public health policy.
