[Multivariate analysis of relationship between breast feeding and infant physical development].

ABSTRACT

Longitudinal analysis with generalized estimating equation (GEE) revealed breast feeding can promote 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 development 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 development with different feeding patterns. It is suggested that intervention of breast feeding should be implemented during perinatal period and 1-2 months after delivery with emphasis on health education.
