Abstract:
Objective:To investigate the distribution and epidemiological patterns of hepatitis B virus（HBV）serological markers among pediatric surgical inpatients in Beijing.Methods:A retrospective cross-sectional study was conducted using data from all surgical inpatients（0?18 years of age）at a tertiary children’s hospital in Beijing between January 2019 and December 2024. Five HBV serological markers（HBsAg，anti-HBs，anti-HBc，HBeAg，anti-HBe）were analyzed and compared across sex，age，and ethnicity.Results:Of 15 339 children included，56.50% were male and 43.50% female；the 6?12-year age group predominated（37.41%），and Han ethnicity accounted for 91.61%. The overall positive rates were 0.78% for HBsAg，75.32% for anti-HBs，7.42% for anti-HBc，0.02% for HBeAg，and 3.05% for anti-HBe. The prevalences of “big three-positive”（HBsAg+/HBeAg+/anti-HBc+）and “small three-positive”（HBsAg+/anti-HBe+/anti-HBc+）patterns were only 0.02% and 0.04%，respectively. Boys had significantly higher anti-HBs（76.02% vs 74.40%）and anti-HBc（8.01% vs 6.69%）positivity than girls. HBsAg peaked in the 1?3-year group（1.75%）and was lowest in the 6?12-year group（0.19%）. Anti-HBs reached its highest level in the 3?6-year group（81.25%）and declined to 56.07% in adolescents（12?18 years）. No ethnic differences were observed.Conclusion:Universal HBV vaccination has achieved remarkable success among surgical inpatients in Beijing，as evidenced by high anti-HBs levels and very low rates of active or chronic infection. However，antibody titers wane with age，underscoring the need for targeted booster strategies for school-aged children.
