By Bhavana KunkalikarJun 8 2023Reviewed by Lily Ramsey, LLM In a recent study published in the Nutrients journal, researchers discussed iron nutrition among preschoolers residing in high-income countries.
Early onset of iron deficiency can have serious consequences on a child's health, including compromised immunity and hindered cognitive and motor development. The importance of iron nutrition during early childhood for public health is significant, although there is still limited understanding of the topic.
The occurrence of depleted iron stores varied between countries, with rates ranging from 7.4% to 31% among preschoolers in the US and UK, respectively. Iron deficiency anemia and iron deficient erythropoiesis had varying prevalence rates across different countries. On the other hand, female preschoolers and those from families having two or fewer children tend to have higher iron intake. Also, young children from disadvantaged families are at a higher risk of iron deficiency. Studies have shown that males and preschoolers from low-income households have lower serum ferritin concentrations.
Dietary trends and iron intakes of preschoolers Few studies have explored the relationship between dietary trends and nutrient intake in children aged between two and five years in high-resource countries, despite the significance of understanding nutrient intake profiles. Only 12 diet quality studies that focused on preschool nutrient intakes and were published in English have reported patterns linked to iron intake.
Conclusion In high-income countries, the prevalence of insufficient iron intake among preschoolers ranges from less than 1% to 66%, and depleted iron stores are found in 7.4% to 31% of cases. Non-dietary factors such as sex, age, household size, and maternal education have an impact on the iron intake of preschoolers.
