Iron Deficiency Anemia Prevention in Infants

Introduction to Iron Deficiency

The Centers for Disease Control and Prevention (CDC) recommends iron supplementation for breastfed infants with minimal solid food intake to prevent iron deficiency anemia, which poses a high risk at 9 months of age 1, 2
Iron stores from birth are depleted by 4-6 months in full-term infants, and iron-deficiency anemia typically manifests around 9 months of age 1, 2
Approximately 15%-25% of breastfed infants develop iron deficiency by ages 9-12 months when they do not receive adequate iron from supplementary foods 1, 2

The CDC identifies breastfed infants who do not consume adequate iron after age 6 months as a high-risk group for iron deficiency anemia, and recommends screening for anemia at 9-12 months 3, 4
Universal screening is recommended between 9-12 months for infants with risk factors, including breastfed infants with inadequate iron from complementary foods 3, 4

The CDC recommends 1 mg/kg per day of iron drops for breastfed infants receiving insufficient iron from supplementary foods by age 6 months (less than 1 mg/kg per day) 5, 4
If anemia is confirmed, increase iron supplementation to 3 mg/kg per day and recheck in 4 weeks 3

Iron-fortified infant cereals should be offered at least twice daily to meet iron requirements 6, 5
Pureed meats (beef, lamb, chicken, or fish) should be introduced as they provide highly bioavailable iron 6
Vitamin C-rich foods (fruits, vegetables, or juice) should be given with meals to enhance iron absorption 6, 5

An increase in hemoglobin ≥1 g/dL after 4 weeks confirms iron-deficiency anemia and warrants continuing treatment for 2 additional months 8
