Slow growth and short stature in children with attention deficit hyperactivity disorder (ADHD): a retrospective study of 493 children who underwent growth hormone provocation testing at one tertiary paediatric endocrine centre

GHD in children with ADHD on psychostimulant medication is rare. GH testing in children with ADHD may not be necessary, particularly if serum IGFBP-3 is in the normal range. We suggest IGFBP-3 could be used as a surrogate marker of GH sufficiency in children with ADHD. However, this needs to be confirmed with a larger study group.
