湖北省儿童乙肝疫苗接种率及影响因素分析

目的　了解湖北省儿童乙肝疫苗接种率及其影响因素。方法　采用分层多阶段随机抽样方法,对84 3名2 0 0 1年出生儿童进行了调查。结果　湖北省儿童乙肝疫苗全程接种率、合格接种率、及时接种率分别为83.2 7%、75 .6 8%、4 9.2 3%。城市、农村1层、农村2层、农村3层全程接种率分别为96 .19%、88.15 %、80 .0 9%、6 8.72 %。儿童未接种或未全程接种乙肝疫苗的主要原因是:(1)本地不提供此类接种服务、(2 )不知道要接种、(3)收费太贵。城市农村分层组群、家庭年收入、儿童出生地点、父母文化程度、儿童监护人乙肝防治知识水平、接种证/卡是否齐全、地形地貌、儿童胎次等9项因素对儿童乙肝疫苗全程接种率有极显著影响(P<0 .0 1) ;儿童民族对乙肝接种率有显著影响(P<0 .0 5 ) ;儿童性别和户口状况对乙肝接种率的影响差异不显著。乙肝疫苗平均接种收费为34.9元,其中贫困农村平均接种费用为37.4元。农村乙肝疫苗接种收费过高影响了农村地区,特别是贫困农村地区乙肝疫苗接种率
