Objective To understand the prevalence of hepatitis B in Zaozhuang population. Methods By random stratified sampling in 2000, 963 people in 312 families were investigated. HBsAg, anti-HBs and anti-HBc were detected by RIA. Results The prevalence of HBsAg, anti-HBs, anti-HBc and HBV was 7.08%, 37.56%, 4.35% and 44.3% respectively. The prevalence of HBsAg in males was higher than that in females (P0.05), in urban areas was higher than that in rural areas (P0.01), and there was no significant difference among different ages and occupational groups (P0.05). Anti-HBs, anti-HBc and HBV infection rates tended to increase with age (P <0.01). The prevalence of HBV infection was higher in males than females (P <0.05) and in rural areas (P <0.05). Conclusion There is a high prevalence of HBV infection in Zaozhuang people. Prevention and control measures should be taken actively to reduce the incidence.
