Dos Santos MM, Nogueira Ndo N, Diniz Ada S: [Effectiveness of different iron supplementation strategies on hemoglobin and ferritin levels among schoolchildren in Teresina, Piaui State, Brazil]. Cad Saude Publica. 2007 Jul;23(7):1547-52.
This study evaluated the effectiveness of supplementation with ferrous sulfate and iron bis-glycinate chelate on hemoglobin and serum ferritin levels among schoolchildren (7-11 years) of both sexes. A randomized community-based trial including 138 anemic children (hemoglobin < 11.5 g/dL) was conducted in Teresina, Piaui State, Brazil. Children were assigned to two treatment groups on an individual basis. One group (n = 71) received 40 mg iron as ferrous sulfate once weekly and the other group (n = 67) received 3.8 mg of iron bis-glycinate chelate-enriched cookies, 3x/week, for 8 weeks. The interventions showed a significant increase (p < 0.01) in hemoglobin levels (1.1g/dL) for children who received ferrous sulfate and 0.9 g/dl in those who received iron bis-glycinate chelate, although not significant in the inter-group comparison (p > 0.05). No effect was observed on body iron for either intervention (p > 0.05). Children with depleted iron stores (< 15 ng/mL) at the beginning of interventions showed increased serum ferritin concentrations after 8 weeks (p < 0.01), although no difference between treatments (p > 0.05) was observed. The results confirm the effectiveness of the iron supplementation interventions and corroborate the use of iron salts or ferrous bisglycinate chelate on a weekly basis to overcome iron deficiency and anemia. |
