摘要： 目的 了解凉山州贫困地区4个重点贫困县6~24月龄婴幼儿营养状况和家长喂养行为,为开展儿童营养与健康干预促进工作提供依据。方法 2018年4-7月采用多阶段随机抽样法,抽取4个重点县1 244名6~24月龄婴幼儿进行体格测量、血红蛋白含量检测和家长问卷调查。结果 凉山州4个重点县6~24月龄婴幼儿贫血患病率为51.9%,低体重率为9.5%,生长迟缓率为25.6%。多因素分析显示,婴幼儿性别、月龄、母亲学历、母亲职业、是否认为满3个月就可以添加辅食、是否知道谷类泥糊状食物是最适合首先添加的辅食、是否知道动物血或红肉是婴幼儿补铁的最好来源、是否知道贫血与铁缺乏有关、是否吃过母乳、6月龄后是否继续母乳喂养是影响婴幼儿营养状况的主要因素(P<0.05)。结论 凉山州贫困地区6~24月龄婴幼儿营养状况亟待改善,婴幼儿看护人喂养知识不足。应加强宣传教育,提高家长的育儿素养,掌握营养包的有效服用方法,纠正不正确的的喂养方式。
