摘要
目的回顾分析2008--2013年定西市健康儿童抗～HBs水平，为制定定西市乙肝控制策略提供参考依据。方法采用随机整群抽样的方法，选择定西市2—7岁儿童632人为研究对象，采用ELISA方法检测入选儿童乙肝抗体（抗-HBs）水平。结果本次调查儿童的抗-FIBs总阳性率为47．15％，不同县、区和性别儿童之间抗一HBs阳性率比较无显著性差异，不同年龄组儿童抗-HBs阳性率比较差异有统计学意义，其中2-岁组儿童阳性率最高，为72．92％，5-岁组儿童阳性率最低，为36．80％。结论抗-HBs对儿童能够起到有效的保护作用，但是抗体效价却随着时间的延长逐渐减弱，因此，儿童群体要及时加强接种，从而有效地控制乙肝发病。
OBJECTIVE It studied the anti-HBs levels of healthy children of Dingxi from 2008 to 2013, in order to provide reference for developing the prevention and control strategy of hepatitis B. METHODS Using random cluster sampling method to choose 632 cas- es of children aged 2 - 7, ELISA method was used for detection of anti-HBs. RESULTS The total anti-HBs positive rate was 47.15%. Among different counties, sex positive rate of anti-HBs had no significant differences. Differences among different age groups of an- ti-HBs positive rate had statistical significance. The highest positive rate of 2 years old group was 72.92%, the lowest positive rate of 5 years old group was 36.80%. CONCLUSION Hepatitis B antibody was effective to protect for children, but with the time pass the an- tibody titer has gradually weakened. So children group meeded timely immunizations, which were effective in the control of hepatitis B incidence.
