A case control study was conducted at the Child Development and Early Intervention Clinic to determine the body iron status of children with ADHD, and study the correlation between the body iron status and ADHD symptoms.
Serum ferritin was measured in newly diagnosed cases with ADHD and compared with that of controls. Correlation was studied between serum ferritin levels and the severity of ADHD symptoms as determined by Conners Rating Scale.
Serum ferritin was found to be significantly lower in children with ADHD (6.04 ± 3.85 ng/mL) as compared to controls (48.96 ± 41.64 ng/mL, P value < 0.001). There was a significant negative correlation between serum ferritin levels and oppositional subscore on Conners Rating Scale.
