摘要
目的了解和评价北京和西安2地幼儿园儿童膳食营养状况,为幼儿合理的膳食营养指导提供科学依据。方法采用双份饭菜法收集幼儿24 h内膳食情况,根据食物成分表计算幼儿24 h内能量和各种营养素的摄入量,并与我国推荐的每日参考摄入量标准进行比较,采用Z评分法进行评价。结果除能量、钙、锌外,北京和西安幼儿园儿童24 h摄入的各种营养素均能达到参考摄入量标准的100%以上;但西安幼儿园儿童维生素A的24 h摄入量未能达到参考摄入量标准的90%。2地学龄前儿童低体重、发育迟缓、消瘦、超重和肥胖的检出率在年龄、地区和性别上差异均无统计学意义(P值均>0.05),低体重、生长迟缓、消瘦、超重和肥胖的检出率分别为0,4.2%,0,3.3%和10.0%。结论北京和西安2地幼儿在饮食结构上存在一定的差异,营养不良问题较少,但营养过剩状况较严重。应根据具体情况进行必要的合理膳食指导。
