[breastfeeding Patterns And Energy Adequacy].

To analyze caloric adequacy in infant feeding six months of age or under, the volume of breast milk consumed was estimated through a regression equation as proposed by Drewett. Energy adequacy was estimated according to World Health Organization guidelines for developing countries and the recommended daily allowance of the Food and Nutrition Board. A cross-sectional analysis was conducted on data from a cohort of 118 infants in a neighborhood around a health center in Campinas, São Paulo, Brazil, with home interviews by trained students. Data were gathered on social and demographic characteristics, infant feeding patterns, duration of breastfeeding, frequency of feedings, and age when breast milk substitutes were introduced. On average, weaning began early, with a 2.7-month median duration of exclusive breastfeeding. Mean breast milk volume was estimated (from frequency of feeding) as 561.0 ml, 558.9 ml and 565.5 ml for children in exclusive, predominant, and supplemented breastfeeding, respectively. Mean energy consumption was adequate for all exclusively breastfed children regardless of age and above the recommended level for infants with supplemented breastfeeding and those already weaned.2064-7

Padrões de aleitamento materno e adequação energética Breastfeeding patterns and energy adequacy

Com o objetivo de analisar o consumo energético de crianças < de 6 meses, em diferentes padrões de aleitamento materno, foram colhidas informações na primeira observação de estudo de coorte. Mães de Campinas, São Paulo, Brasil, foram entrevistadas em seus domicílios sobre: condições sócio-demográficas, características do aleitamento materno, consumo alimentar dos lactentes. A adequação energética foi estimada pelo volume de leite materno consumido com base na equação de regressão de Drewett et al. ¹; os valores de referência seguiram recomendação da Organização Mundial da Saúde ² e da Food and Nutrtition Board ³. A população de estudo (118) caracteriza-se como de classe média baixa, em condições satisfatórias de moradia e saneamento. O desmame inicia-se precocemente, com mediana de duração do aleitamento materno exclusivo de 2,7 meses. O volume de leite materno consumido foi de 561ml, 558,9ml e de 515,2ml, em aleitamento materno exclusivo, aleitamento materno com água e/ou chá e complementado com outros alimentos, respectivamente. O consumo energético médio foi adequado para as crianças em aleitamento materno exclusivo e acima do recomendado para crianças em amamentação complementada ou desmamadas.<br>To analyze caloric adequacy in infant feeding six months of age or under, the volume of breast milk consumed was estimated through a regression equation as proposed by Drewett 1.
