QUISPE, Custodio  e  TERUKINA, Ricardo. Levels of glycemia in at term newborns adequate for gestational age breast-fed exclusively or not. An. Fac. med. [online]. 2007, vol.68, n.2, pp.125-135. ISSN 1025-5583.

Introduction: Newborns exclusively breast-fed (EBF) may present low levels of glycemia in the first hours of life and their monitoring is very important. Severe hypoglycemias are associated with neurological sequels. Objectives: To determine the influence of breastfeeding exclusive or not over glycemia levels in the newborn during the first 24 hours of life. Design: Cuasiexperimental kind of study. Setting: Immediate care and child care services, Instituto Nacional Materno Perinatal, Lima, Peru, a teaching hospital. Participants: Breast-fed newborns. Interventions: Ninety newborns were distributed in 3 groups according to the kind of feeding: a) 30 EBF; b) 30 breastfeeding plus maternized milk; and, c) 30 breastfeeding plus glucose solution. Newborns admited fulfilled criteria of inclusion and previous consent of the mother a sample of blood was taken from the mother and the newborn to determine glycemia at birth and at 2, 4, 6, 12, 18, and 24 hours. Main outcome measures: Newborn glycemia levels. Results: Newborns EBF have a tendency to a more prolonged decrease in glycemia levels and a farther increase, than those breastfed plus maternized milk and breast milk plus glucose solution; these diferences were significant with a p < 0,0001 and p = 0,006 respectively. Conclusions: The levels of glycemia < 40 mg/dL (hypoglycemia) was higher in those EBF (16,7%), followed by those breast-fed plus maternized milk (10%) and none in those breast-fed plus glucose solution. Weight lose was greater in those newborns with EBF.
