Abstract
BackgroundMicronutrient deficiencies can compromise the development potential of school-aged children, and their later health and productivity as adults. School feeding and school-based fortification approaches have been utilized globally to redress nutritional deficiencies in this age group.ObjectiveWe explored the acceptability and micronutrient impact of a Bangladesh Government supported school-based micronutrient fortification program for children attending rural primary schools in 10 disadvantaged sub-districts.MethodsWe applied a mixed methods approach. The quantitative component assessed the impact of micronutrient fortification on 351 children aged 6–11 years using a cohort pre-post research design with a control group. The qualitative component explored the acceptability of the intervention using focus group discussions, body mapping and semi-structured interviews with teachers, school-going children and school authorities.ResultsDaily consumption of fortified biscuits by primary school children had a significant positive impact on mean levels of iron, folic acid, vitamin B12, retinol and vitamin D controlling for sex, baseline deficiency status, CRP, and H. pylori. Levels of anemia and vitamin D deficiency were also significantly reduced. Qualitative findings indicated the widespread acceptability of the daily biscuit. Teachers perceived students to be more attentive in class, less tired, and some attributed better school performance to biscuit consumption. Children reported similar improvements in concentration and energy levels.ConclusionsThis study is among the first in Bangladesh to comprehensively assess a school-based fortification program in terms of its acceptability and impact on micronutrient status of children aged 6–11 years of age. While results strongly support this modality of school feeding, research on the cognitive impacts of micronutrient fortified biscuits will help clarify the case for scaled-up investments in school- based feeding program in Bangladesh and other low and middle income countries.
Highlights
It is well established that malnutrition in early life can compromise the development potential of children, and their later health and productivity as adults [1]

Summary
It is well established that malnutrition in early life can compromise the development potential of children, and their later health and productivity as adults [1]. Lack of diversity of diet is a major determinant of children’s poor micronutrient profile, with deficiencies linked to increased risk of infection, stunted growth and diminished cognitive performance [2, S1 Appendix]. For these reasons, interventions to address micronutrient deficiencies in schoolaged children have been proposed as a means of improving their health, growth and cognitive performance. Micronutrient deficiencies can compromise the development potential of school-aged children, and their later health and productivity as adults. School feeding and school-based fortification approaches have been utilized globally to redress nutritional deficiencies in this age group
