Nutrients patterns and attention deficit hyperactivity disorder among Egyptian children: a sibling and community...

Attention Deficit Hyperactive Disorder (ADHD) diagnosis has been growing among children, with great public health concern. The relationship between nutrient intake pattern and ADHD remains unclear.

To identify the nutrient intake patterns and its association with ADHD in children.

The study involved 146 children with ADHD, 141 control sibling, and 146 community controls. ADHD diagnosis was confirmed using the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-V) criteria following the assessment by the long-form Conner's Scale. Dietary intakes were assessed using a semi-quantitative food frequency questionnaire. Nutrients patterns were identified using the principal component analysis (PCA).

ADHD children have significantly higher mean total energy intake than community controls and siblings (8867.9, 4481.9 and 7308.2 KJ, respectively, p < 0.001). Four nutrient patterns extracted by the PCA explained 75.9% of the total variance. Lower tertiles of "predominantly calcium-phosphorus; pattern 1" and "predominantly-vitamins; pattern 3" were significantly associated with increasing odds of ADHD, compared to community controls (p for trend: 0.002 and 0.005, respectively), while the same associations were noted in "predominantly-vitamins" and "predominantly Zinc-Iron; pattern 2" when compared to siblings (p for trend: <0.001 and <0.001, respectively). However, Higher tertiles of macronutrients; pattern 4" were associated with increased ADHD odds, compared to either community controls or siblings (p for trend: 0.017 and <0.001, respectively).

Lower intakes of nutrients patterns of minerals and vitamins, and higher intakes of macronutrients were associated with increased likelihood of ADHD in children.
