Efectividad relativa del hierro bis-glicinato quelado (Ferrochel) y del sulfato ferroso en el control de la deficiencia de hierro en mujeres embarazadas. La efectividad relativa de la suplementación diaria con sulfato ferroso (FeSO4) o con hierro aminoquelado (Ferrochel, FeAAC) se estudió en 145 mujeres de menos de 20 semanas de embarazo distribuidas en dos grupos. Un grupo (71 mujeres) the suplementado con 15 mg de hierro por día provenientes de Ferrochel, y el otro (74 mujeres) con 40 mg de hierro por día provenientes de sulfato ferroso. Se efectuaron mediciones de hemoglobina, ferritina y saturación de trasferrina al ingreso al programa (<20 semanas de embarazo), entre 20-30 semanas y entre 30-40 semanas. La ingesta ininterrumpida por 13 semanas o más se consideró adecuada. La disminución en los valores de todos los parámetros medidos the menor en el grupo tratado con Ferrochel, a pesar de que la dosis the mas pequeña. Depauperación de hierro se encontró en 30.8% de las mujeres tratadas con Ferrochel y en 54.5% de aquellas tratadas con sulfato ferroso. Entre los factores informados como responsables del abandono del tratamiento se encontró que el sabor the el factor mas importante para las consumidoras de sulfato. Sabor indeseable no the informado por las mujeres que consumieron Ferrochel. Se concluye que la suplementación diaria con Ferrochel the significativamente mas efectiva a pesar que la dosis usada the menor que la dosis de sulfato ferroso.

The relative effectiveness of daily supplementation of iron deficiency during pregnancy using 15 mg/day of iron from iron-bis-glycinate chelate (71 pregnant women), or 40 mg iron from ferrous sulfate (74 pregnant women) was evaluated by measuring hemoglobin, transferrin saturation and serum ferritin, at the beginning of the study (<20 weeks of pregnancy) and at 20-30 weeks and 30-40 weeks thereafter. Ingestion for 13 weeks or more was considered adequate. Seventy three percent of the Ferrochel consuming group and 35% of the ferrous sulfate consuming group were considered to have taken the treatment adequately. The decrease in levels of all the measured parameters was significantly less pronounced in the group that consumed Ferrochel in spite of the lower treatment dose. Iron depletion was found in 30.8% of the women treated with Ferrochel and in 54.5% of the women than consumed ferrous sulfate. Of the factors responsible for non compliance taste was reported in 29.8% of the ferrous sulfate consumers and none in the groups that consumed Ferrochel. It is concluded that daily supplementation with Ferrochel was significantly more effective, in spite of the lower dose, than supplementation with ferrous sulfate.

Por meio de dosagem de ferritina sérica, transferrina sérica, hemoglobina e hematócrito, caracterizou-se o estado nutricional de ferro de 79 gestantes adolescentes de primeira consulta pré-natal (<FONT FACE=Symbol>£ </FONT>20 semanas de gestação), atendidas na Rede Básica de Saúde de um Município da Grande São Paulo. Todos os valores hematológicos estudados foram menores entre as gestantes do segundo trimestre gestacional em relação às do primeiro, sendo as diferenças estatisticamente significativas (p<0,05) apenas para hemoglobina. Verificou-se que 64,3% e 32,1% possuíam, respectivamente, menos de 500 mg e 300 mg de ferro em suas reservas, sendo que 5,4% apresentavam carência grave do mineral. Segundo critério da Organização Mundial da Saúde 19,0% das gestantes eram ferro-deficientes (saturação da transferrina < 16,0 %) e 13,9% eram anêmicas (Hemoglobina < 11 g/dl).

The objective of this study was to characterize iron nutritional status of 79 pregnant adolescents, at first prenatal consultation (<= 20 weeks of gestation), in the Primary Health System of a district of Great São Paulo, through the serum ferritin, serum transferrin, hemoglobin and hematocrit determinations. All the hematologic values studied were smaller for the pregnant adolescents in the second gestational trimester than for the ones in the first. Statistically significant differences (p.<.0.05) were found just for hemoglobin. It was verified that 64.3% and 32.1% had, respectively, less than 500.mg and 300.mg of organic iron reservations, and 5.4% presented serious lack of this mineral. By World Health Organization criterion 19.0% of the pregnant women were iron-deficient (Saturation of Transferrin <.16%) and 13.9% were anemic (Hemoglobin.<.11 g/dl).
