营养强化辅食补充对甘肃贫困农村婴幼儿智力发育的影响

目的初步探讨辅食补充对贫困农村婴幼儿智力发育的影响。方法从甘肃省5个贫困县选取4~12个月的婴幼儿分成两组,所有儿童均在保持其家庭习惯的辅助食品添加的前提下,每天再补充1包不同配方的营养补充物,其中配方1组补充了蛋白质和微量营养素,配方2组补充能量达到配方1组的同等的能量。两组均补充维生素A。补充期间,儿童每3个月进行一次体格测量,每6个月进行一次血红蛋白测量,两组儿童观察到满24个月为止。儿童满24个月龄时进行智力发育的测定。结果24个月时配方1组、配方2组儿童的总发育商分别为97.2、95.5,有显著性差别(P<0.05),其中大运动区也有显著性差别(P<0.05)。两配方组儿童在辅食的补充时间、营养状况、性别构成、母亲文化程度等没有显著差别,但是24个月时儿童血红蛋白值两配方组有显著性差别(P=0.011)。结论补充营养素强化的辅助食品有利于贫困农村4~12个月婴儿的智力发育。

Formula II provided the same energy as formula I . Both groups were supplemented with vitamin A, weight and height measurements have been done every 3 months, and hemoglobin tests were done every 6 month. Development quotient was measured when they were aged 24 month. RESULTS: Development quotient of 475 children were tested. The difference of Development quotient between the two groups is statistically significant ( P < 0.05), gross motor development also is different (P < 0.05), there are no difference in time of supplements, nutrition status, sex ratio, mother' s education between two group, but hemoglobin and anemia prevalence of children in formula I group is significant lower than Formula II group.
