Name the three infant populations deemed at risk for iron deficiency according to AAP selective screening.

• A. Preterm infants
• B. Infants not receiving iron fortified formula
• C. Infants fed human milk older than 6 months not consuming an iron rich diet
• D. Preterm infants; Infants not receiving iron fortified formula; Infants fed human milk older than 6 months not consuming an iron rich diet

Answer: (D)

This item tests which infant groups are considered at risk for iron deficiency by the AAP selective screening guidelines. The three populations identified are: preterm infants, who have lower iron stores at birth and rapid postnatal growth that increases iron needs; infants not receiving iron-fortified formula, meaning their iron intake may be insufficient without fortified formula or other iron sources; and infants fed human milk beyond 6 months who are not consuming iron-rich foods, since human milk provides relatively little iron and iron needs rise after about 6 months unless iron-rich foods or fortified sources are added. Because each group represents a distinct at‑risk category, the comprehensive answer includes all three populations.
