母乳喂养与婴儿体格发育关系的多因素分析

Multivariste Analysis of Relationsbip Between Breast Feeding and Infant Physical Development

广义估计方程的纵向分析显示，哺乳或母乳量对婴儿体格发育呈良好的正向促进作用；典型（典则）相关的横向分析显示，以母乳量为主的蛋白质摄入作用首先使婴儿向高而瘦长的体格发育，支持蛋白质对婴儿生长发育影响较大的理论。喂养方式相同而母乳量不同者，婴儿体格发育水平亦不同，在比较不同喂养方式下的婴儿体格发育时应注意。建议母乳喂养的干预应抓住围产期和生后１～２个月这两个时机，并用健康教育方法促使其改进。

ongitudinal analysis with generalized estimating equation (GEE )revealed breast feeding can pro-mote infant physical development and growth,and cross-sectional analysis with canonical correlation showed protein intake with breast milk as its main source brought about infants to develop physically tall and lean at first,which might support the theory that protein intake affects more on their devefopment and growth.The extent of infant physical development and growth varied with the amount of breast milk of his or her mother,which should be caught attention in comparison of infant physical develop-ment with different feeding patterns. It is suggested that intervention of breast feeding should be imple-mented during perinatal period and 1～2months after delivery with emphasis on health education.
