Micronutrient Supplementation Effect on Children
Multimicronutrient deficiency is common in children especially in infants and preschoolers. Poor maternal stores leading to poor fetal stores, poor complementary foods deficient in vitamins and minerals, fussy eaters and dislike of vegetables and fruits by children are some of the causes that have lead to micronutrient deficiencies in these children. However, several studies have suggested that intervention in form of fortification of food or micronutrient supplementation over a prolonged period of time tends to improved growth especially height, cognitive abilities and leads lesser infections in these children. In a study in Chennai, addition of powder containing ferrous glycine phosphate (elemental iron = 28 mg) and riboflavin (1 mg) to the noon meal in 65 school children between 5-9 years for a period of 100 days in 6 months decreased the prevalence of anemia from 69% to 32.8% and prevalence of angular stomatitis from 21% to 0%(1). Similarly another study from Chennai studied effect of a micronutrient supplement containing vitamin A, vitamin B2, vitamin B6, B12, folic acid, niacin, calcium pantothenate, vitamin C, E, iron, lysine and calcium in 211 children from 5-15 years of age daily for 9 months. They found that hemoglobin, serum vitamin A, serum vitamin E, serum vitamin B12 and serum folic acid increased significantly as compared to those children (202 children) who received no supplementation(2) CHAMPION study (Children's Health and Mental Performance influenced by Optimal Nutrition) carried out in school children in Bangalore found that supplementation with higher concentration of multimicronutrients (100% of the recommended daily allowance) led to better linear growth as compared to supplementation with lower concentration of multimicronutrients (15% of RDA). Both groups had equal increase in cognitive performance(3). Martorell et al found that weight gain during the first 2 years of life had the strongest association with schooling (better weight gain, more schooling)(4).

Studies in preschoolers who were supplemented vitamin A, zinc, iron have also found that growth and weight increases significantly(5, 6).

Isolated deficiencies of micronutrients are rare and usually multimicronutrient deficiencies co-exist. The first 3 years of life are most crucial and vulnerable to the hazards of under nutrition(7) as this is the time of faster physical growth, maximum brain development and development of immunity. Thus all efforts should be made to give a balanced and nutritious diet to these children and micronutrient supplements to meet 100% RDA for achieving physical growth and mental development to the optimum genetic potential.
