摘要

The presentation highlighted that micronutrient deficiencies, particularly iron deficiency, are very common in low birthweight infants and extend into later life. Of particular concern is the high incidence (25-50%) of iron deficiency reported in pre-school children and its deleterious effects on cognition and neu-robehavior. It thus becomes imperative to prevent iron deficiency in early infancy and childhood to have optimal neurodevelopment. While term infants have sufficient iron stores (which shift between storage pool and hemoglobin), most infants will be self-sufficient in iron until 6 months, needing supplementation thereafter. The preterms would need higher doses and earlier supplementation in view of limited stores and rapid growth. Risks of iron excess such as increased infection and impaired growth have to be kept in mind during supplementation. Cord clamping, blood transfusions, phlebotomy would affect iron status of these infants and need to be considered during iron supplementation.
