Background: Micronutrient deficiencies largely affect pediatric population worldwide. In India, pediatric category is more prone to iron deficiency, the most common micronutrient deficiency disorder which produces haematological as well as non-hematological disturbances. This study aimed to identify the impact of iron deficiency on cognitive function and anthropometric changes in pediatric populations.

Methods: A hospital based, prospective observational study was conducted at Department of Pediatrics in Rajah Muthiah Medical College and Hospital, 127 participants were enrolled in this study. BKT kit of Intelligence, Electronic weighing machine, Stadiometer, BMI Calculator by CDC guidelines and patient’s haemoglobin values were used in this study.

Results: Out of 127 patients, 66 patients had iron deficiency with anemia and remaining 61 had iron deficiency without anemia. Cognitive behaviour was assessed based on the norms and majority were under the category- dull average (52 patients) followed by average (45 patients) and other’s had single digit patients. Growth charts of Indian Academy of Pediatrics were used to assess anthropometric characteristics and majority were in the underweight category (61.4%) followed by average category (38.6 %).

Conclusions: Low cognitive scores and underweight were found in participants with low haemoglobin levels. Hence, our study provides convincing evidence that iron plays a vital role in the cognition, motor and physical growth. Awareness about the importance of iron and the health issues associated with its deficiency was also provided to the participants.
