摘要
目的了解儿童乙肝流行和乙肝疫苗接种状况,为制定或调整乙肝疫苗接种策略提供依据。方法按照两阶段抽样法,抽取8个行政村15岁以下儿童978人,采静脉血3～5ml,ELISA法检测HBVM。结果15岁以下儿童HBsAg阳性率0.92%,与1991年15岁以下儿童HBsAg阳性率10.12%比较,有显著性差异,乙肝疫苗接种保护率90.91%。15岁以下儿童HBsAb阳性率40.49%,地区、城乡和性别分布均衡,乙肝抗体水平有随着年龄增加而下降的趋势,但1～5岁组有低峰。15岁以下儿童乙肝疫苗调查接种率91.82%,报告接种率87.89%,地区差异均有显著性,两者各年龄组之间乙肝疫苗接种率均随年龄增大而降低。结论马鞍山16年乙肝防治效果非常显著,要继续开展新生儿乙肝免费接种,加强流动儿童乙肝疫苗接种工作。
