ABSTRACT
Objective: This study aimed to define the estimated average requirement and therecommended dietary allowance of iron for Indian children and adolescents. Methods: TheEstimated average requirement was derived for children aged 1-17y, from the meanbioavailability-adjusted daily physiological iron requirement, which in turn was estimatedusing a factorial method. This consisted of mean daily iron losses from the body andadditional iron required for tissue growth and storage, while also defining the variance of eachfactor to derive the Recommended dietary allowance. Results: The estimated averagerequirement of iron for children ranged from 5.6 to 11.0 mg/d in children aged 1-9y. Foradolescents aged 10-17y, these ranged from 10.8 to 18.4 mg/d and 15.4 to 18.5 mg/d foradolescent boys and girls, respectively. Conclusion: New estimates of estimated averagerequirement for iron in Indian children are presented, and same may be used to inform ironsupplementation and food fortification policies.
