Attention-deficit/hyperactivity disorder (ADHD) is a common chronic neurodevelopmental disorder, which starts in childhood and can last to adulthood. The main characteristics of ADHD are attention deficit and/or hyperactivity impulse which are not commensurate with the development level. In the early identification, diagnosis and standardized treatment of ADHD children, attention should be paid to the influence of nutrition factors on the risk of disease, the influence of digestive tract symptoms and comorbidity on nutrition status, as well as the monitoring, evaluation and guidance of physical growth and nutrition level during treatment and follow-up. The nutritional management of ADHD children will help to reduce the related nutritional risks of ADHD children, improve the nutritional status, and increase curative effect.
