RESUMEN

Objetivo: analizar el estado nutricional del hierro en gestantesadolescentes de tercer trimestre. MetodologÝa estudioanalÝtico de corte transversal con 276 adolescentes entre 10 y19 a±os, en tercer trimestre de gestaci¾n de la Empresa Socialdel Estado (ese) Metrosalud (MedellÝn, 2011-2012), con datosde hemoglobina, volumen corpuscular medio, concentraci¾nde hemoglobina corpuscular media e ingesta de suplementode hierro. La ferritina sÚrica se analiz¾ en 178 gestantes,controlada por proteÝna C-reactiva. Se utilizaron medidas detendencia central, dispersi¾n, porcentajes y pruebas de Chi2,anova, Kruskal-Wallis y U de Mann-Whitney. Resultados:la prevalencia de anemia fue 17,1% en el tercer trimestrede gestaci¾n y por deficiencia de hierro, 51%. La medianade ferritina sÚrica fue 13,3 Ág/L (RQ 7,7 Ág/L-17,9 Ág/L);s¾lo el 5,6% (n = 9) present¾ valores adecuados de ferritina.Las madres que tomaron suplemento de hierro diariamentepresentaron mejores concentraciones de hemoglobina yferritina, frente a aquellas que no lo hicieron, Hb 12,1g/dL vs.11,7 g/dL (p = 0,019) y ferritina sÚrica 14,6 Ág/L vs. 7,0 Ág/L(p = 0,000). Discusi¾n hubo altas prevalencias de anemia yferropenia en las gestantes, asociadas con la no adherencia alsuplemento de hierro...

ABSTRACT

Objective: to analyze the nutritional status of iron in pregnantadolescents in their third trimester. Methodology: a crosssectionalanalytical study with 276 adolescents between theages of 10 and 19 in the third trimester of pregnancy fromthe ESE Metrosalud State Social Enterprise (MedellÝn 2011-2012). Data was collected for hemoglobin, mean corpuscularvolume, mean corpuscular concentration and the ingestionof iron supplements. Serum ferritin levels were analyzed in178 pregnant adolescents and were controlled by C-reactiveprotein. Central tendency measures, dispersion, percentagesand Chi 2, anova, Kruskal-Wallis and Mann-Witney U testswere employed. Results: anemia prevalence was 17.1% inthe third trimester, 51% because of iron deficiency. Medianserum ferritin was 13.3 Ág/L (RQ 7.7 Ág/L-17.9 Ág/L); only5.6% (n=9) showed adequate ferritin levels. Mothers who tookdaily iron supplements exhibited greater concentrations ofhemoglobin and ferritin when compared with those who did nottake any supplement, Hb 12.1g/dL vs 11.7 g/dL ( p = 0.019) andserum ferritin 14.6 Ág/L vs7.0 Ág/L (p = 0.000). Discussion:there was high prevalence of anemia and iron deficiency inthe expectant mothers, which was associated with a lack ofadherence to the iron supplement...
