In preterm babies, when should elemental iron supplementation begin and continue until (assuming no multiple transfusions)?

• A. 1 month of age and continue until 12 months
• B. At birth and continue until 6 months
• C. 2 weeks and continue until 12 months
• D. 4 months and continue until 18 months

Answer: (A)

The important concept here is preventing iron deficiency during a period of rapid growth when preterm babies have very limited iron stores. Most iron transfer from the mother happens in the third trimester, so babies born preterm start life with small stores and then use them quickly as their growth rate is high in the first year. Without supplementation, they’re at risk for iron deficiency anemia, which can affect neurodevelopment. Starting elemental iron at about 1 month of age provides iron soon enough to meet ongoing needs and prevent deficiency as stores decline. Continuing until 12 months aligns with the time frame when dietary iron from iron-fortified formula or solid foods becomes the main source of iron and the infant is transitioning away from relying on stored iron. If no multiple transfusions have occurred, this window helps ensure adequate iron status during a critical development period. Starting earlier (at birth or within the first weeks) or delaying beyond 1 month would miss the window when stores are most depleted and the risk of deficiency is highest, making 1 month to 12 months the best approach for preterm infants without transfusions.
