Insights
New iron requirements for Indian children and adolescents are established. These estimates for estimated average requirement (EAR) and recommended dietary allowance (RDA) will guide public health policies on iron intake.
Area of Science:
- Nutritional Science
- Public Health Nutrition
- Pediatric Nutrition
Background:
- Iron deficiency is a significant public health concern globally, particularly in developing countries.
- Adequate iron intake is crucial for cognitive development and overall health in children and adolescents.
- Existing iron requirements may not accurately reflect the needs of the Indian pediatric population.
Purpose of the Study:
- To establish the Estimated Average Requirement (EAR) and Recommended Dietary Allowance (RDA) for iron in Indian children and adolescents.
- To provide updated nutritional guidelines for iron intake tailored to the specific demographic.
- To inform evidence-based policies for iron supplementation and food fortification.
Main Methods:
- The EAR was calculated using a factorial method, estimating daily physiological iron requirements adjusted for bioavailability.
- Mean daily iron losses and additional iron needs for growth and storage were quantified.
- Variances in these factors were determined to derive the RDA.
Main Results:
- The EAR for iron in children aged 1-9 years ranged from 5.6 to 11.0 mg/day.
- For adolescents aged 10-17 years, the EAR ranged from 10.8 to 18.4 mg/day.
- Specific EAR ranges were identified for adolescent boys (15.4–18.5 mg/day) and girls (15.4–18.5 mg/day).
Conclusions:
- New estimates for the EAR of iron in Indian children and adolescents have been determined.
- These updated requirements can guide the development of effective iron supplementation strategies.
- The findings support the refinement of food fortification policies to address iron needs in this population.
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.
