To evaluate the efficacy of iron supplements given at intervals corresponding to the mean life of red blood cells compared to weekly supplementation, in reducing the prevalence of preschool anemia. Method: Ninety-nine children from public day care centers with ages from 24 to 59 months old were randomly divided into two groups. This is a randomized comparative study. All the children received 40 doses of 30 mg of ferrous sulfate during a 10-month intervention period. Group 1 received once weekly supplementation and Group 2 received supplementation in two 5-month cycles, each cycle consisting of one month of supplementation (20 workdays) and four months without supplementation. Results: The prevalence of anemia after the supplementation regimens reduced from 20.20% to 5.05% (p < 0.0005); the reduction was not significantly different between the two groups (p = 0.35). The mean hemoglobin concentration increased in both groups (Group 1: 0.27 g/dL; p < 0.016 and Group 2: 0.47 g/dL; p < 0.0005) without significant differences between the groups (p = 0.17). Conclusions: The two regimens reduced the prevalence of anemia, were low-cost, and with high rate of compliance. The regimen in cycles was evaluated easier to apply than the weekly one.
