Some but not all breast‐fed infants benefit from iron supplementation
Full‐term healthy breast‐fed infants in Newfoundland Canada have previously been shown to benefit from iron supplements early in infancy by increasing developmental motor scores (Friel et al., J. Pediatrics, 2003). To test this hypothesis in another Canadian province, 82 infants in Manitoba were ran...

Full‐term healthy breast‐fed infants in Newfoundland Canada have previously been shown to benefit from iron supplements early in infancy by increasing developmental motor scores (Friel et al., J. Pediatrics, 2003). To test this hypothesis in another Canadian province, 82 infants in Manitoba were randomized to receive 7.5 mg of supplemental iron as ferrous sulphate (I) or placebo (P) once a day from 1 to 6 months of age. All infants were breast‐fed at one month of age and were encouraged to continue exclusive breast‐feeding to 6 months before introducing solid foods. Blood samples were collected by venipuncture at 4 and 12 months of age. Anthropometric and demographic data was collected at 1, 4, 6 and 12 months of age when a Bayley Developmental assessment was conducted. Although P infants weighed more at birth (P: 3.63 ± 0.4 vs. I: 3.42 ± 0.5 kg P<0.05) this difference did not persist after one month of age. At 4 months ferritin (I: 110 ± 91 vs. P: 75 ± 48) was higher and transferrin receptors (I: 20 ± 4.4 vs. P: 22 ± 6) were lower in the iron‐supplemented group.
