Maternal gestational iron status and infant haematological and neurodevelopmental outcomes

Abstract

AbstractPrevention of iron deficiency (ID), the most common micronutrient deficiency in infants and children, begins prenatally by ensuring adequate fetal loading. Adequate intrauterine iron status is crucial for normal fetal brain development, postnatal brain performance and prevention of early postnatal iron deficiency, particularly in infants fed exclusively human milk. Adequate fetal loading may be achieved in some cases through adequate maternal iron levels prior to pregnancy and oral iron supplementation during pregnancy. However, because so many women are iron‐deficient leading up to pregnancy, coupled with the negative iron balance induced by pregnancy, a large number of women remain iron‐deficient during pregnancy. More consistent iron‐specific early screening and more effective iron delivery approaches are needed to solve this global problem.
