Abstract:

Background. The effectiveness of commonly suggested public health interventions to control childhood iron- deficiency anemia has been low.

Objective. To determine whether iron provided in Sprinkles daily or in a higher dose once weekly affected hemoglobin, serum ferritin levels, and serum transferrin receptor levels, and to determine whether there were dif- ferences in the effects of the two regimens.

Methods. In this cluster-randomized, community- based trial conducted in rural areas of Bangladesh, 136 children aged 12 to 24 months with mild to moderate anemia (hemoglobin 70–109 g/L) were randomly allo- cated to receive Sprinkles daily (12.5 mg of elemental iron, n = 79) or once weekly (30 mg of elemental iron, n = 73) for 8 weeks. Hemoglobin, serum ferritin, and serum transferrin receptor were assessed at the start and end of the intervention.

Results. In both groups, there were significant increases in hemoglobin and serum ferritin and a significant decrease in serum transferrin receptor (p < .01). There were no significant differences between the groups in the increases in hemoglobin (16.1 ± 13.2 g/L for the group receiving Sprinkles daily and 12.3 ± 13.3 g/L for the group receiving Sprinkles once weekly) and serum ferritin (10.6 and 5.7 g/L, respectively). The decrease in serum transferrin receptor also did not significantly differ between the groups (median, –2.5 and –1. 8 mg/L, respectively). The prevalence rates of iron-deficiency anemia, depleted iron stores, and tissue iron deficiency decreased significantly within each group (p < .01), with no significant differences between the groups.

Conclusions. Home fortification of complementary foods with Sprinkles given either daily or once weekly improved iron-deficiency anemia and iron status among young children.
