Abstract:
OBJECTIVETo explore the serological infection rate of hepatitis B virus (HBV) in general population aged over one year old in Beijing and to provide information for control and prevention of the disease.
METHODSA multistage randomized cluster sampling was carried out in general population of Beijing, aged over one year old. Every study subject's hepatitis B immunization history and main risk factors were investigated through questionnaire. Venous blood samples were collected and then tested for five hepatitis B serological antigens and antibodies by means of Abbott Microparticle Enzyme Immunoassy method.
RESULTSThe prevalence rates of HBsAg, anti-HBs, anti-HBc and total HBV infection rate were 3.49% (95% CI:2.99-3.99), 37.79% (95% CI: 36.46-39.12), 35.04% (95% CI: 33.72-36.35) and 35.09% (33.78-36.40) respectively. The age standardized rates were 3.02% ,42.47% ,26.86% and 26.90% respectively.
CONCLUSIONAchievement in hepatitis B control and prevention was made in Beijing since the prevalence rate of hepatitis B surface antigen had been below 1% for children aged less than 5 years old. As for the general population, the prevalence rate of hepatitis B surface antigen had reduced to
