Multi-micronutrient Fortified Beverage Delivered through the School-based System Improved Iron Status and Test Scores of Children

Abstract

Objectives: This study aimed to evaluate the effectiveness of fortified beverage on the nutritional status and school performance of school children. Methods: There were 5000 schoolchildren aged 6 to 12 years old participated in the study. Weight and height were measured among the 5000 children while only 1500 were sub-sampled for the evaluation of hemoglobin level and only 3600 children took the tests. Test questions were developed and administered by school supervisors. Children were fed 200 ml ready-to-drink juice fortified with iron, zinc, lysine, vitamin A and C for 120 days. The beverage was delivered through the school system by a feeding coordinator. Data on hemoglobin level, weight, height and test results were collected at base and end of the study. Results: At end of the study, prevalence of anemia was reduced from 100% to 60%. The rate of underweight decreased significantly from 16.5% at baseline to 13.5% at end of the study. Percentage mean test scores increased significantly between base and end of the study: English (40% to 60%), Math (35% to 58%), Science (32% to 58%). Conclusions: Consumption of 200 ml fortified juice drink has contributed to the reduction of anemia and increased tests scores of children.
