摘 要：
目的:研究100%苹果汁对贫困农村儿童营养的改善作用,探讨如何发挥社会组织在改善儿童营养工作中的新途径和新作用。方法:抽取甘肃省陇西县6所农村小学3~6年级452名学生作为研究对象,随机分为干预一组(n=175)、干预二组(n=144)和对照组(n=133),干预一组每人每日饮用250m L的100%苹果汁、干预二组每隔1天饮用100%苹果汁、对照组保持正常饮食,干预期4个月;干预前后分别对受试者进行72 h膳食调查。结果甘肃省陇西县9~12岁农村儿童营养状况不容乐观,能量、蛋白质、维生素A、维生素B1、B2及钙的摄入量均有不同程度的缺乏。干预一组干预前后,平均每人每日能量、维生素B1、B2、维生素C及钾、钙、铁的摄入量均增加,差异均有统计学意义;干预二组干预前后,平均每人每日能量、维生素B1、B2、维生素C及钾、钙、铁、的摄入量均增加,差异均有统计学意义。对照组2次调查结果发现,平均每人每日能量、维生素B1、B2、及钾的摄入量均增加,钠的摄入量减少,差异均有统计学意义。结论:甘肃省陇西县农村9~12岁儿童营养状况不容乐观,存在营养不均衡状况,虽营养状况良好的人群占大数,但也存在一定比例的营养不良和超重肥胖的情况。苹果汁的摄入能调整膳食结构,改善营养状况,促进能量、维生素和矿物质的吸收,这为高效实现农村义务教育学生营养干预提供了新方法和新思路。
