Amamentação e crescimento infantil: um estudo longitudinal em crianças do Rio de Janeiro, Brasil, 1999/2001

Abstract

Various studies have shown significant differences in growth patterns between breastfed and formula-fed infants. This paper aims to evaluate the effect of predominant breastfeeding duration on anthropometric profile and to detect determinants associated with growth in Brazilian infants. Four hundred and seventy nine infants were studied in a health center in Rio de Janeiro through a longitudinal study with four follow-up waves at 0.5, 2, 6, and 9 months. The response variables were body weight and length, collected according to a standardized procedure. Data analysis was performed having longitudinal mixed-effects model as the main statistical procedure. Gestational age, birth weight, and birth length were positively associated with weight and length gains. The positive effect showed that the longer breastfeeding lasts, the greater the weight gains. Infants born through vaginal delivery presented lower weight gains than those born by cesarean delivery. The results emphasize the need for health programs encouraging breastfeeding practices up to the sixth month of life.

The effect of breastfeeding in body composition of young children

“…Studies with Brazilian population 10,11 also used one of these indexes to evaluate the nutritional state, and not the fat component evaluation itself. To our knowledge, this is the first Brazilian study that focused on the effect of PBF over body fat on children.…”

“…A study 9 performed in 12 cities verified that children breastfed for a longer period showed greater weight gain velocity. Spyrides et al 10 , in a longitudinal study, found that, the longer the breastfeeding lasts, the higher is the child weight. Araújo et al 11 , however, did not find relationship between the breastfeeding duration and obesity at 4 years old.…”

Fatores associados à interrupção precoce do aleitamento materno: um estudo de coorte de nascimento em dois municípios do Recôncavo da Bahia, Brasil

“…Destacam-se ainda os fatores de proteção contra as doenças conferidos pelo leite materno, os quais o tornam alimento ideal, capaz de satisfazer as necessidades nutricionais, em especial nos dois primeiros anos de vida. Desse modo, o aleitamento materno promove o crescimento e o desenvolvimento pleno das crianças 1,2,3,4,5,6,7 .…”
