摘要：In the developing countries, the growth of the breastfed children is faster than that of bottlefed children, certain factors present in the mother's milk having a protective effect against the episodes of diarrhoea and acute respiratory infections. In the industrialized countries, the breast-feeding proceeds more than one choice of the mother. The present study relates to the analysis of the longitudinal growth, and the way of feeding from birth to 18 months of 1820 French infants. The choice of the way of feeding of the newborns depends of the geographical (and cultural) origin of the mother, and the gestation period (at term/preterm babies). The duration of the breast-feeding decreased among immigrant women, in comparison to the practices in the country of origin. In the majority of the cases, the Dietetic Lacteous Foods supports a faster ponderal growth during the first weeks of the life, but the mother's milk would have a preventive effect on the overweight and obesity during childhood. The proteinic concentration of the mother's milk decreases gradually during the period of lactation of the mother, but this protein concentration is higher in the mother of a preterm child; the pediatrists and the neatologists should thus encourage the breast-feeding of the preterms one.
