[Macronutrients in milk of undernourished mothers]. / Macronutrientes en leche de madres desnutridas.

In a prospective, no experimental and comparative analysis, the relationship between the mother's nutritional conditional and their macronutrient's concentrations was evaluated in 40 samples from mothers who had children 15 days to 6 months old, in a hospital setting at the Emergency room of the Pediatric Ward of Maracaibo's University Hospital in Maracaibo, Venezuela in one year period. Milk from two groups of 20 mothers each was analyzed: Group A (Experimental), mothers with undernourishment and Group B (Control), mothers with adequate nutritional status. Fat content was 3.8 +/- 0.32 g/dl and 5.5 +/- 1.08 g/dl respectively (p = 0.0001); proteins were 1.8 +/- 0.21 g/dl and 2.4 +/- 0.32 g/dl respectively (p = 0.0001), and carbohydrates were 6.06 +/- 0.43 g/dl and 5.7 +/- 0.45 g/dl respectively (p = 0.0136). In addition, caloric value was also different: 65.92 +/- 15. 16.68 kcal/l and 83.25 +/- 9.4 kcal/dl (p = 0.0002). The undernourished were in the range of group V Graffar Méndez-Castellano, confirming the relationship between undernutrition and poverty. It is concluded that the proteins, fat concentrations and the caloric value in the breast milk from undernourished mothers are of lower value than the nourished well mothers.

Macronutrientes en leche de madres desnutridas / Macronutrients in milk of undernourished mothers

Estudio prospectivo, no experimental y comparativo que evaluó la relación entre el estado nutricional materno y las concentraciones de macronutrientes de leche materna madura. Se estudiaron 40 muestras de madres con hijos en edades entre 15 días y 6 meses, hospitalizados en el Servicio de Emergencia Pediátrica del Hospital Universitario de Maracaibo, entre Septiembre 2006 y 2007 . Se dividieron en: Grupo A estudio (n= 20) muestras de madres con desnutrición clínica y Grupo B control (n= 20) eutróficas. Se analizaron las concentraciones de macronutrientes comparándose entre sí: grasas 3,8 ± 0,32 g/dl en el A y 5,5±1,08 g/dl en el B, estadísticamente significativo (p=0,0001); proteínas 1,8 ± 0,21 g/dl en el A y 2,4 ± 0,32 g/dl en el B, estadísticamente significativo (p=0,0001) y carbohidratos 6,06 ± 0,43 g/dl en el A y 5,7±0,45 g/dl en el B estadísticamente significativo (p= 0,0136). El valor calórico de la leche fue de 65,92 ± 16,68 Kcal/dl en el Grupo A y de 83,25 ± 9,40 Kcal/dl en el grupo control, estadísticamente significativo (p=0,0002). Las desnutridas pertenecían al grupo V de Graffar Méndez Castellano confirmando la relación entre desnutrición y pobreza. Se concluye que la concentración de grasas y proteínas, así como el valor calórico en la leche madura de este grupo de madres desnutridas son menores que en el grupo control.
