Effect of supplementation with iron fortified biscuits on the hemoglobin status of children in rural areas of Shimoga, Karnataka.

Abstract

To assess the efficacy of iron fortified biscuits, in high and low dosages, on the hemoglobin levels of anemic school going children aged 6 to 12 y. The nutrition intervention was conducted in primary schools located in villages at Shimoga district, Karnataka. School children aged 6 to 12 y who were anemic, with hemoglobin level <11.5 g/dl were considered for the nutrition intervention. The sampling design undertaken was quasi experimental with pre and post stages of outcome. The children enrolled were divided into two groups. One group received high dosage of iron fortified biscuits (30 mg of elemental iron/6 biscuits) and the second group received a relatively lower dosage of iron fortified biscuits (1.8 mg of elemental iron/6 biscuits) for a period of 120 d. The hemoglobin levels were estimated pre and post fortified biscuit supplementation by cyanomethemoglobin method. There was an increase in the mean hemoglobin level of children which was found to be higher in group I (high iron fortified biscuits) (1.06 g/dl) compared to group II (low iron fortified biscuits) (0.41 g/dl), significant at 0.01 level (t = 3.84**). In the current nutrition intervention, both high and low iron fortified biscuits led to a significant enhancement in the body weight and hemoglobin status of anemic school children in a rural setup. The nutrition intervention clearly highlights biscuits as an ideal fortification vehicle for addressing anemia.
