Prevention and screening of iron deficiency in infants

Iron deficiency is a frequent condition during infancy. Recent studies relate it with neurodevelopment, although there are not conclusive results. Most organizations are not recommending iron supplementation in normal infants but there is consensus about supplementing if there are risk factors. There is also controversy about screening and some groups recommend screening infants at risk, and others propose general screening. The purpose of this article is to review the requirements of iron during infancy and the different current recommendations.
