BackgroundHepatitis B virus (HBV) infection remains a global public health problem and it is an important cause of acute, chronic and fulminant hepatitis, liver cirrhosis and hepatocellular carcinoma. The prevalence of HBV infection in Hong Kong over the past decade remained unchanged at 10%, despite the implementation of universal neonatal and availability of adult vaccination. We suspect that the current state of affairs is attributable to inadequate awareness and knowledge of HBV transmission and prevention in the general population, resulting in a low rate of uptake of HBV vaccination by the lay public. Therefore, we have embarked in this study to evaluate the awareness and knowledge on HBV infection in our local Chinese population, their attitude on the prevention of horizontal transmission of HBV, and the use of HBV vaccination, especially in those who were born before the era of universal neonatal vaccination.MethodsThe factors associated with HBV screening, vaccination uptake, and knowledge were examined in a face-to-face questionnaire survey on a group of adult Chinese in Hong Kong.ResultsWithin this group, 14% was considered to have good knowledge for HBV infection, and 26% had HBV vaccination. Age, occupation, having children, and family monthly income, are independent factors associated with vaccination.ConclusionThis study suggests insufficient public awareness of HBV infection in the Hong Kong Adult Chinese population.
