  • Title: Normal hemoglobin at the age of 1 year does not protect infants from developing iron deficiency anemia in the second year of life.
    Author: Moser AM, Urkin J, Shalev H.
    Journal: J Pediatr Hematol Oncol; 2011 Aug; 33(6):467-9. PubMed ID: 21792044.
    Abstract:
    BACKGROUND: Iron deficiency anemia (IDA) is the most common hematologic disorder worldwide. Measures to prevent IDA in infants have been successful with questionable sustainability. AIM: To evaluate the incidence of developing IDA in the second year of life, in infants who were nonanemic at the age of 1 year on routine blood test. METHODS: Blood samples were obtained from 193, 24-month-old toddlers, from 2 large clinics of both main sectors in Southern Israel, comparable for lower economic status. IDA was defined as hemoglobin < 11 gr% and microcytosis as mean corpuscular volume < 70 fL. RESULTS: IDA was detected in 8 of 118 Bedouins (5 males) and in 10 of 75 Jewish (6 males) infants (P < 0.01). The probability of a nonanemic child to develop IDA in the second year of life for the whole study population was 9.3% (18 of 193 infants) and significantly higher in the Jewish population (13.3.0% vs. 6.8%, P < 0.01). CONCLUSIONS: Given the difficulty of toddlers to maintain a non-IDA status, and the very low probability of iron overload, our results clearly support the need to continue iron supplementation into the second year.
