Objective To investigate the level of hepatitis B （HBV） antibody among healthy people in Chengdu in 2016. Methods Four districts were selected from three layers in Chengdu, and the healthy people were di- vided into seven age groups. Then at least 30 people were selected randomly from each age group. Hepatitis B antibody levels were measured by ELISA, and the data were analyzed using SPSS 11.0. Results 884 serum samples were assayed. The hepatitis B antibody positive rate was 73.64%. The hepatitis B antibody positive rate was the highest in the 〈 1 year age group; and also was higher in people with permanent registered resi- dence than in floating people ; higher in urban areas than in suburban and rural areas. Conclusion Management of floating people should be enhanced, and immunization against hepatitis B should be strengthened. Serological detection should be enhanced and non - responders be appropriately revaecinated to keep the positive rate of hepatitis B antibodies at a high level so as to prevent and control hepatitis B.
