ESCUDERO V, Luz S et al. Nutritional status of iron in pregnant adolescents: Medellín-Colombia. Rev. Fac. Nac. Salud Pública [online]. 2014, vol.32, n.1, pp.71-79. ISSN 0120-386X.

OBJECTIVE: to analyze the nutritional status of iron in pregnant adolescents in their third trimester. METHODOLOGY: a cross-sectional analytical study with 276 adolescents between the ages of 10 and 19 in the third trimester of pregnancy from the ESE Metrosalud State Social Enterprise (Medellín 2011-2012). Data was collected for hemoglobin, mean corpuscular volume, mean corpuscular concentration and the ingestion of iron supplements. Serum ferritin levels were analyzed in 178 pregnant adolescents and were controlled by C-reactive protein. Central tendency measures, dispersion, percentages and Chi 2, ANOVA, Kruskal-Wallis and Mann-Witney U tests were employed. RESULTS:nemia prevalence was 17.1% in the third trimester, 51% because of iron deficiency. Median serum ferritin was 13.3 µg/L (RQ: 7.7 µg/L-17.9 µg/L); only 5.6% (n=9) showed adequate ferritin levels. Mothers who took daily iron supplements exhibited greater concentrations of hemoglobin and ferritin when compared with those who did not take any supplement, Hb: 12.1 g/dL vs 11.7 g/dL (p = 0.019) and serum ferritin 14.6 µg/L vs7.0 µg/L (p = 0.000). DISCUSSION: there was high prevalence of anemia and iron deficiency in the expectant mothers, which was associated with a lack of adherence to the iron supplement.
