Long‑term stimulant use linked to modest adult growth effects in children with ADHD
In a retrospective cohort of 12,866 children aged 6 to 11 years, those diagnosed with ADHD and treated with methylphenidate had a higher adult BMI (24.3 vs. 23.3) and a slightly increased risk of overweight/obesity (adjusted odds ratio [OR], 1.60) compared with matched controls. They also showed a small but statistically significant increase in short stature risk (adjusted OR, 1.08).
Clinical takeaway: Track BMI and growth closely in children with ADHD on methylphenidate and consider early lifestyle interventions.
