Systematic Review Question

What is the relationship between iron from supplements consumed during infancy and toddlerhood and growth, size, and body composition?

Conclusion Statement

Moderate evidence indicates that human milk-fed infants who are supplemented with iron do not have greater growth, and may have slower growth, than human milk-fed infants not supplemented with iron. (Grade: Moderate)

Insufficient evidence is available to determine the relationship between iron from supplements consumed during infancy and body composition during infancy. (Grade: Grade not assignable)

Insufficient evidence is available to determine the relationship between iron from supplements consumed during infancy and growth, size, and body composition beyond age 12 months. (Grade: Grade not assignable)

Insufficient evidence is available to determine the relationship between iron from supplements consumed after age 12 months and growth, size, and body composition. (Grade: Grade not assignable)
