We estimated the impact of universal hepatitis B immunization using 18-year data of women who are of childbearing age in South Korea.
We used hepatitis B surface antigen (HBsAg) and antibody (anti-HBs) data of 145,993 women aged 20-49 years during 2001-2018 at the Gangnam CHA Medical Center. Annual prevalences of HBsAg and anti-HBs positivity were calculated and tested for linear trend. We conducted age-period-cohort (APC) analysis to obtain period and cohort effect.
Overall proportion of HBsAg positivity was 3.5% (n = 5050) and anti-HBs positivity was 75.3% (n = 109,907) during the study period. HBsAg positivity percentage decreased from 5.1% in 2001 to 2.5% in 2018 (P < 0.001) while anti-HBs positivity increased from 59.9% to 75.8% (P = 0.002). Average annual percent change of HBsAg positivity was -5.9% (95% confidence interval (CI): -6.9%, -4.8%). The period and cohort RR curve identified a consistent decrease in HBsAg positivity over time and across generations.
We observed a concurrent decrease in HBsAg and an increase in anti-HBs seropositivity among Korean women of childbearing age, implicating success in preventing vertical transmission.
我们利用韩国育龄妇女 18 年的数据估计乙型肝炎免疫的普遍影响。
我们使用了 2001 年至 2018 年在江南 CHA 医疗中心年龄在 20-49 岁的 145993 名妇女的乙型肝炎表面抗原(HBsAg)和抗体(抗-HBs)数据。计算了 HBsAg 和抗-HBs 阳性的年度流行率,并对其进行了线性趋势检验。我们进行了年龄-时期-队列(APC)分析,以获得时期和队列效应。
在研究期间,总 HBsAg 阳性率为 3.5%(n=5050),抗-HBs 阳性率为 75.3%(n=109907)。HBsAg 阳性率从 2001 年的 5.1%下降到 2018 年的 2.5%(P<0.001),而抗-HBs 阳性率从 59.9%增加到 75.8%(P=0.002)。HBsAg 阳性率的年平均百分比变化为-5.9%(95%置信区间(CI):-6.9%,-4.8%)。时期和队列 RR 曲线表明,HBsAg 阳性率随着时间的推移和代际的变化持续下降。
我们观察到韩国育龄妇女的 HBsAg 呈下降趋势,抗-HBs 血清阳性率呈上升趋势,这表明预防垂直传播取得了成功。
