  Purpose

Aim: 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. 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.

Primary Outcome Measures:
  • Initial and final blood hemoglobin concentration [ Time Frame: 10 months ]

Enrollment: 99

Study Completion Date: July 2008
Primary Completion Date: February 2007 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Group 1:iron weekly supplementation Drug: iron supplementation
40 doses of 30 mg of ferrous sulfate during a 10-month intervention period
Active Comparator: Group 2: cycle supplementation
two 5-month cycles, each cycle consisting of one month of supplementation (20 workdays) and four months without supplementation.
Biological: iron supplementation
supplementation in two 5-month cycles, each cycle consisting of one month of supplementation (20 workdays) and four months without supplementation.

Detailed Description:
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).
