CONTEXT Iron deficiency anemia in infants can cause developmental problems. However, the relationship between iron status and cognitive achievement in older children is less clear. OBJECTIVE To investigate the relationship between iron deficiency and cognitive test scores among a nationally representative sample of school-aged children and adolescents. DESIGN The National Health and Nutrition Examination Survey III 1988-1994 provides cross-sectional data for children 6 to 16 years old and… 

Figures and Tables from this paper

Iron deficiency, prolonged bottle-feeding, and racial/ethnic disparities in young children.

Children with prolonged bottle-feeding and Mexican American children are at higher risk for iron deficiency and Screening practices and nutritional counseling should be targeted at these high-risk groups.

Iron Deficiency in Early Childhood in the United States: Risk Factors and Racial/Ethnic Disparities

Hispanic toddlers are more likely than white and black toddlers to be overweight and not in day care, and the higher prevalence of these risk factors among Hispanic toddlers may account for their increased prevalence of iron deficiency.

Effect of Iron Deficiency Anemia on Academic Performance among Primary School Children

Anemia due to iron deficiency anemia between children had effect on academic performance impairments and encourage health educational program for parents about children’s nutritional requirements specially iron requirement and frequent blood testing is required.


The adverse effects on cognitive and educational test performance due to IDA in preschool and school-age children appear more transitory in nature than the effects on development in infants and imply that treatment of IDA through iron supplementation programs may be beneficial and have immediate effects.

Schoolchildren with Learning Difficulties Have Low Iron Status and High Anemia Prevalence

In this study, schoolchildren with DIRS had lower hemoglobin and serum ferritin levels when compared to those without, and was statistically associated with a risk of anemia with a weighted OR of 1.62.

Effects of Iron Deficiency on Cognitive Function in School Going Adolescent Females in Rural Area of Central India

Scholastic Performance, IQ and Scores of Mental balance, Attention & Concentration, Verbal Memory and Recognition were decreased in iron deficiency girls, both anemic and non anemic as compared to the non iron deficient girls.

Iron Deficiency Anemia in Children

The main principles of treatment include investigation and elimination of the underlying cause, iron supplementation, improvement of nutri - tion, and education of the patient and family.

Prevalence of Iron Deficiency Anemia among Female Elementary School Children in Northern Jeddah, Saudi Arabia

It was concluded that iron deficiency anemia is a problem among young girls, especially among those of age 12 years in western region of Saudi Arabia, and it is recommended that the iron-folate supplementation program for pregnant women be expanded to non-pregnant women, including young girls.

The iron status of children and youth in a community mental health clinic is lower than that of a national sample.

The ferritin levels of children and youth seen in a mental health clinic sample were significantly lower than those of the same-aged subjects in a national sample, suggesting compromised iron status may be an additional biological risk factor for cognitive, behavioral, and psychiatric problems in pediatric populations served by the community mental health Clinic.



Poorer Behavioral and Developmental Outcome More Than 10 Years After Treatment for Iron Deficiency in Infancy

Severe, chronic iron deficiency in infancy identifies children who continue at developmental and behavioral risk >10 years after iron treatment, and these children are identified in increased concerns about anxiety/depression, social problems, and attention problems.

Prevalence of iron deficiency in the United States.

Iron deficiency and iron deficiency anemia are still relatively common in toddlers, adolescent girls, and women of childbearing age and were more likely in those who are minority, low income, and multiparous.

Iron deficiency anemia and educational achievement.

Findings from the present study indicate that iron supplementation among iron-deficient anemic children benefits learning processes as measured by the school achievement test scores.

Iron deficiency anemia and iron therapy effects on infant developmental test performance.

Persistent lower scores suggest either that iron therapy adequate for correcting anemia is insufficient to reverse behavioral and developmental disturbances in many infants or that certain ill effects are long-lasting, depending on the timing, severity, or chronicity of iron deficiency anemia in infancy.

Effect of iron therapy on behavior performance in nonanemic, iron-deficient infants.

It is concluded that iron deficiency, even in the absence of anemia, results in biochemical alterations that impair behavior in infants.

Iron deficiency anemia: adverse effects on infant psychomotor development.

When iron deficiency progresses to anemia, but not before, adverse influences in the performance of developmental tests appear and persist for at least 3 months despite correction of anemia with iron therapy, suggesting prevention of iron deficiency anemia in early infancy becomes the only way to avoid them.

Reticulocyte hemoglobin content to diagnose iron deficiency in children.

Reticulocyte Hb content level was the strongest predictor of iron deficiency and iron deficiency anemia in children and holds promise as an alternative to biochemical iron studies in diagnosis.
