Effect of timing of cord clamping on the iron status of infants at 3 months.

ABSTRACT

OBJECTIVE: To determine the effect of timing of cord clamping on iron stores of term infants at 3 months of age. DESIGN: Prospective randomized clinical trial. SETTING: Tertiary hospital. SUBJECTS: 107 term neonates born to mothers with uncomplicated pregnancies and with hemoglobin more than 10 g/dl. METHODS: The 107 infants were randomized to either early (n = 48) or late (n = 59) clamping groups at the time of delivery. Outcome measures evaluated were serum ferritin and hemoglobin in the infant at 3 months age. RESULTS: The groups were comparable for maternal age, parity, weight, supplemental iron intake in pregnancy, infant's birth weight, gestation and sex. Maternal and cord ferritin and hemoglobin values at birth were comparable. The infant ferritin at 3 months were also similar. CONCLUSIONS: Iron stores at 3 months in term infants are not influenced by timing of cord clamping at birth.
