摘要
目的了解中国沿海、内陆和西部地区3～12岁儿童血浆维生素A营养状况。方法从2002年中国居民营养与健康状况调查的6类地区中一、二、三、四类农村,88个调查点的儿童血样中,每个年龄段随机抽取男女血样各6份,利用高效液相色谱法测定血浆维生素A含量。结果中国农村沿海、内陆、西部3～12岁儿童血浆维生素A缺乏率分别为5.5%、15.4%和10.2%,边缘缺乏率分别为40.5%、53.8%和50.1%。牧区和非牧区3～12岁儿童血浆维生素A缺乏率分别为5.1%、11.7%,边缘缺乏率分别为45.4%、51.5%。结论中国3～12岁儿童血浆维生素A缺乏在农村沿海、内陆和西部具有显著差异,在牧区与非牧区也具有显著差异。
