OBJECTIVE
This study aimed to define the estimated average requirement and the recommended dietary allowance of iron for Indian children and adolescents.
METHODS
The Estimated average requirement was derived for children aged 1-17y, from the mean bioavailability-adjusted daily physiological iron requirement, which in turn was estimated using a factorial method. This consisted of mean daily iron losses from the body and additional iron required for tissue growth and storage, while also defining the variance of each factor to derive the Recommended dietary allowance.
RESULTS
Results: The estimated average requirement of iron for children ranged from 5.6 to 11.0 mg/d in children aged 1-9y. For adolescents aged 10-17y, these ranged from 10.8 to 18.4 mg/d and 15.4 to 18.5 mg/d for adolescent boys and girls, respectively.
CONCLUSIONS
New estimates of estimated average requirement for iron in Indian children are presented, and same may be used to inform iron supplementation and food fortification policies.
目的
本研究旨在为印度儿童和青少年定义铁的推荐膳食允许量和平均需要量。
方法
通过使用因子法，从平均生物利用度调整后的每日生理铁需求量中得出 1-17 岁儿童的平均需要量。这包括从体内流失的平均每日铁量以及组织生长和储存所需的额外铁量，同时还定义了每个因素的方差，以得出推荐膳食允许量。
结果
结果：1-9 岁儿童的铁平均需要量估计为 5.6 至 11.0mg/d。对于 10-17 岁的青少年，男孩和女孩的范围分别为 10.8 至 18.4mg/d 和 15.4 至 18.5mg/d。
结论
提出了印度儿童铁平均需要量的新估计值，可用于为铁补充和食物强化政策提供信息。
