摘　　要：【目的】对婴幼儿膳食摄入和血微量元素进行分析,确定当前主要的儿童营养问题,为制定营养改善对策提供科学依据。【方法】对在北京大学第三医院儿童保健中心定期进行体检的311例6～36月儿童进行膳食分析和血微量元素测定。【结果】各种营养素的摄入除锌外（70.9%）均达到DRIs的标准,微量元素和矿物质测定发生钙缺乏19.3%,锌缺乏8.4%,铁缺乏2.3%。与正常组比较,钙缺乏组碳水化合物供能比增多（55.63±4.59 vs 53.70±5.46,P〈0.05）,锌缺乏组脂肪供能比过多（33.27±6.78 vs 30.91±4.96,P〈0.05）,铁缺乏组维生素C摄入过少（140.78±68.34 vs 87.42±41.56,P=0.041）,两者间有明显相关性。【结论】婴幼儿膳食状况良好,为预防微量元素缺乏,父母要注意培养婴幼儿科学的膳食习惯。[Objective] To understand the present status of nutrition and trace elements for children under 3 years and give suggestion for improving children＇s health.
