摘要： 目的 调查本地区学龄儿童血清25-羟基维生素 D[25-(OH)D],维生素A、E水平,了解学龄儿童维生素A、D、E的营养状况,为本地区学龄儿童合理补充微量营养素和预防相关疾病的发生提供理论依据。方法 收集2015年5月-2016年4月于佳木斯大学附属第一医院、建三江人民医院、宝泉岭中心医院等10余家医院门诊及住院部接受维生素A、D、E水平检测的所有6~12岁儿童资料6 030例,分别比较不同性别、年龄段、检测季节的维生素A、D、E水平和维生素营养状况差异。结果 佳木斯地区6~12岁儿童维生素A不足检出率为55.1%,充足检出率为44.9%;维生素E不足检出率为0.67%;维生素D缺乏检出率为37.9%,不足检出率为24.2%,充足检出率为37.9%;不同性别间维生素A、D、E水平比较差异无统计学意义(P>0.05)。各年龄段维生素A、D、E水平比较差异无统计学意义(P>0.05)。季节间比较差异有统计学意义 (P<0.05) 。结论 佳木斯地区学龄期儿童维生素A、D水平较低,各季节间维生素A、D、E差异明显,应引起家长及各阶层医务工作者的高度关注。
