衡阳市居民乙型病毒性肝炎HBsAg携带率及抗-HBs流行率调查

目的了解并评价衡阳市居民乙肝病毒表面抗原（hepatitisBsurfaceantigens，HBsAg）携带率和抗体流行情况。方法于2012年6～7月采用多阶段随机抽样方法，抽取石鼓区、常宁市2个县（市区）7个乡7个村1044名1—59岁人群，进行问卷调查和血标本采集，由湖南省疾病预防控制中心统一检测HBsAg、乙型肝炎表面抗体（抗．HBs）2项指标。结果衡阳市居民乙肝HBsAg携带率为6．13％，10岁以下儿童已降至1．21％，HBsAg携带率随着年龄的增加而增长，农民HBsAg携带率高于其它职业人群。不同性别、地区、文化程度人群间无差异。衡阳市居民乙肝抗一HBs阳性率为54．21％，不同性别、年龄、地区、职业、文化程度人群间均无差异。结论衡阳市乙肝防治已达到卫生部〈〈2006—2010年全国乙型病毒性肝炎防治规划》中提出的总体目标，但乙肝防治任务依然艰巨，仍需加强新生儿乙肝疫苗接种策略，做好围产期母婴阻断；进一步加强成人健康教育与健康促进，提倡知情自愿自费接种乙肝疫苗。

Prevalence of the HBsAg and antibodies against HBV among residents in Hengyang City
