Iron status in Nigerian mothers and their newborns

An evaluation of iron status was carried out on 364 Nigerian pregnant women from Niamey at delivery and in cord blood from their newborns. Anemia, defined as a low hematocrit value, was observed in 46% of pregnant women. Iron deficiency, recognized by a combination of, at least, 2 abnormal values in the 3 independent indicators measured (serum ferritin level, erythrocyte protoporphyrin concentration and transferrin saturation) was present in 47.8% of pregnant women. Anemia was associated with iron deficiency in 60.1% of cases in anemic mothers. A correlation between maternal and newborn iron indicators was found. This study points out the necessity for developing strategies in Sahelian countries to combat iron deficiency during pregnancy by specific measures in combination with more general interventions.
