广元地区散居儿童营养素摄入量分析

本文对广元地区１０００例２月至１０岁散居儿童进行了营养素摄入量分析，所有受检儿童均经体格检查，包括身长、体重的测定，ＯＴ与ＰＨＡ皮肤试验、血红蛋白与血清碱性磷酸酶等测定，将受检儿童所摄入的食物中种类和量输入微机营养程序进行分析：结果：６月以内婴儿除铁质摄入不足外，其余如热能、蛋白质、钙、ＶＢ１、ＶＢ２、尼克酸，ＶＣ及磷等均摄入正常。６—１２月时钙和磷摄入量开始下降，各占供给量的７５％和７３％。１岁以后蛋白质、钙和磷均逐渐下降，各年龄组除碳水化合物热能摄入量稍偏低外，蛋白质和脂肪热能均在标准范围内。必需氨基酸摄入量分析：３—４月时苯丙氨酸、酪氨酸、亮氨酸和苏氨酸摄入量稍偏低，２岁时的苯丙氨酸、酪氨酸和赖氨酸摄入量减少，随年龄增长多数氨基酸均有不同程度的摄入缺乏。
