Brief Summary
It is common in many populations that babies develop iron deficiency or iron deficiency anemia (that is, too few healthy red blood cells due to lack of iron). This is due to rapid growth in infancy combined with limited sources of iron in the infant diet. The amount of iron the baby receives across the placenta during pregnancy is another important factor. This study focuses on infants who are born with less than the usual amount of iron in their bodies. The purposes of the study are to assess effects of lower iron at birth on infant behavior and development and to determine if providing iron supplements to such infants beginning at 6 weeks fosters healthier development. Another part of the study will determine the effects of iron deficiency anemia at different times during infant development.

Outcome Measures
Primary Outcomes (1)
Infant behavior and development
6 weeks; 9 and 18 months
Secondary Outcomes (2)
Low or marginal birth iron
6 weeks
Infant anemia
9 and 18 months
Study Arms (7)
Low birth iron
EXPERIMENTALInfants with low birth iron who receive vitamins A and D + iron
Marginal birth iron 1
EXPERIMENTALInfants with marginal birth iron randomized to receive vitamins A and D + iron
Marginal birth iron 2
ACTIVE COMPARATORInfants with marginal birth iron randomized to receive vitamins A and D without iron
Normal birth iron
ACTIVE COMPARATORInfants with normal birth iron who receive vitamins A and D without iron
Combined ID
EXPERIMENTALMarginal-birth-iron vitamins only-treated infants who have IDA at 9 mo.
Early postnatal IDA
EXPERIMENTALInfants with IDA at 9 months whose cord blood was collected at birth but who were not assessed and assigned to vitamins with or without iron at 6 weeks
Late postnatal IDA
EXPERIMENTALInfants with IDA at 18 months whose cord blood was collected at birth but who were not assessed and assigned to vitamins with or without iron at 6 weeks. These infants were also not anemic when screened at 9 months.
Interventions
a single daily dose of 1-2 mg/kg of elemental iron (5 mg from 6 wk to 9 mo and 15 mg from 9 to 18 mo.) and 1500 IU vitamin A and 500 IU vitamin D from 6 wk to 18 mo.
a single daily dose (liquid) of 1500 IU vitamin A and 500 IU vitamin D from 6 wk to 18 mo.
Infants who become iron deficient/anemic at 9 or 18 mo will take a single daily dose of 3 mg/kg of elemental iron for 3 months.
Eligibility Criteria
You may qualify if:
- infants born at Maternity and Children's Hospitals of Fuyang city in China
- healthy term newborns from uncomplicated pregnancies for hematology screening
- healthy full-term singleton infants with cord Hb and ferritin in the low-marginal or normal range for developmental testing
You may not qualify if:
- perinatal complications
