In this study, we aimed to identify specific biomarkers for ADHD diagnosis in children and adolescents by urinary metabolomic profiling. However, large-sample urinary metabolomic studies in children with ADHD are relatively rare. Attention-deficit/hyperactivity disorder (ADHD) is one of the most common psychiatric disorders in childhood. Metabolomics has also been used to diagnose disease, discover novel biomarkers, and elucidate pathophysiological pathways.

Objectives: Knowledge of the urinary metabolomic profiles of healthy children and adolescents plays a promising role in the field of pediatrics.
