Randomized Controlled Trial Clinical TrialBody iron and individual iron prophylaxis in pregnancy--should the iron dose be adjusted according to serum ferritin?
This study aims to evaluate iron prophylaxis in pregnant women from the individual aspect, i.e. according to serum ferritin levels at the beginning of pregnancy, and to assess which dose of iron would be adequate to prevent iron deficiency (ID) and iron deficiency anaemia (IDA) during pregnancy and postpartum. A randomised, double-blind study comprising 301 healthy Danish pregnant women allocated into four groups taking ferrous iron (as fumarate) in doses of 20 mg (n=74), 40 mg (n=76), 60 mg (n=77) and 80 mg (n=75) from 18 weeks gestation (inclusion) to 8 weeks postpartum. Iron status markers [serum ferritin, serum soluble transferrin receptor (sTfR), haemoglobin] were recorded at 18, 32 and 39 weeks gestation and 8 weeks postpartum. ⋯ In the prevention of ID, we suggest 80-100 mg ferrous iron/day to women having ferritin
