Micronutrient deficiencies in children with iron deficiency

Area of Science:

• Pediatric Nutrition
• Clinical Micronutrient Research
• Public Health Pediatrics

Background:

• Iron deficiency (ID) and micronutrient deficiencies (MNDs) are critical pediatric public health issues.
• ID is frequently diagnosed, but co-occurring MNDs are often missed.
• This study investigated MNDs associated with ID and iron deficiency anemia (IDA) in children.

Purpose of the Study:

• To identify and quantify other micronutrient deficiencies in children diagnosed with ID or IDA.
• To assess the prevalence of specific MNDs alongside ID and IDA.
• To understand the clinical implications of co-occurring deficiencies.

Main Methods:

• Prospective single-center study of 157 children (6 months–18 years) with suspected ID/IDA.
• Comparison of micronutrient levels (including zinc, folic acid, vitamins A, D, E, B12) between children with and without ID/IDA.
• Statistical analysis to determine the risk and significance of deficiencies.

Main Results:

• 48% of children had ID, and 17% had IDA.
• Children with ID showed significantly lower zinc levels (p=0.020) and higher zinc deficiency prevalence (p<0.001).
• Children with IDA had significantly higher risk and lower levels of folic acid (p=0.018) and zinc (p<0.001).

Conclusions:

• Children with ID/IDA are at increased risk for deficiencies beyond iron.
• Zinc and folic acid deficiencies are particularly common comorbidities.
• Comprehensive nutritional screening is crucial for pediatric patients with ID/IDA.
