Although iron is essential for auditory neural maturation during the perinatal period, there is a paucity of data regarding the concomitant effect of in utero iron deficiency on auditory neural maturation in late preterm and term infants. The present prospective study is planned with an objective to determine the association of in utero iron deficiency as evaluated by cord ferritin with auditory neural maturation at birth in ≥ 34 weeks GA infants.
