不同喂养方式对婴儿生长发育的影响

本文对２４０例健康婴儿的喂养方式与其体重、身高、头围、胸围值进行了动态观察测定，经方差分析，三种喂养方式比较，人乳与人工：６月内无论男女体重、身高、头围、胸围存在显著性差异（Ｐ＜０．０５）。人乳与混合：１月－３月组男体重、身高、头围、胸围和４月－６月组男体重、身高、胸围，女体重、胸围存在显著性差异（Ｐ＜０．０５）。混合与人工：１月－３月组女体重、身高和４月一６月男身高及女胸围存在显著性差异（Ｐ＜０．０５）。７月一１２月组三种喂养方式体重、身高，无差异（Ｐ＞０．０５），头围、胸围存在极显著性差异（Ｐ＜０．０１）。分析结果提示：人乳能促进婴儿生长发育。

The Patterns of Distinct Feeding for the Effect of Physical Development in Infants

he relationship between distinctive feeding and the weight length,head circumference andchest circumference in 240 cases of healthy infants were observed continuously. The results byChi-square test analysis showed that the values of weightk,length and chest circumference in themale and female infants inder six months of age,between breast-feeding and artificial feeding haddifference sinnificantly(p<0.05),Between breast-feeding and mixedness-feeding. the values of weight,length,circumference and chest circumference in male in-fants in 1-3months of age had difference significantly,the weinht,length and chest circumferencein male infants,the chest circumference in female infants in4-6months of age had differencesignificantly(p<0.05).Between mixedness feeding and artificial feeding,the values of weight,length in female and length in male infants in 1-3month of age had difference significantly, thevalues of length in male infants and the head circumference in female infants in 4-6months of agehad difference significantly(p<0.05).Between the three feeding patterns, the values of age hadno difference,but the values of head circumference had difference very sygnificantly(p<0.01),These above- mentioned results showed that the breast-feeding have important role for devel-opment of physical and central nervous system of infants.
