The effects of stimulant medication on the growth of hyperkinetic children
Insights
Stimulant medications may temporarily slow growth in children with hyperkinetic behavior syndrome, affecting weight and stature during early treatment. However, long-term adult height and weight remain unaffected by these growth effects.
Area of Science:
- Pediatric Pharmacology
- Child Psychology
- Growth and Development
Background:
- Hyperkinetic behavior syndrome (attention-deficit/hyperactivity disorder) is often treated with stimulant medications.
- Concerns exist regarding potential long-term effects of these medications on child development, particularly growth.
Purpose of the Study:
- To review existing literature on the impact of stimulant medication on growth in children with hyperkinetic behavior syndrome.
- To assess the evidence for growth suppression and its characteristics.
Main Methods:
- Literature review of studies examining stimulant medication effects on growth in children.
- Analysis of data on weight, stature, and adult height/weight outcomes.
Main Results:
- Evidence indicates temporary growth retardation in weight and slowing of stature during initial years of stimulant treatment.
- No significant effect on final adult stature or weight was observed.
- Temporary growth effects appear dose-dependent and influenced by drug holiday practices.
Conclusions:
- Stimulant medications may cause transient growth deceleration in prepubertal children with hyperkinetic behavior syndrome.
- Long-term adult growth outcomes are not adversely affected.
- Further research is needed on growth effects during treatment that extends through pubescence.
Abstract:
This article reviews the literature on possible growth-suppressing effects of stimulant medications in the long-term treatment of children with the hyperkinetic behavior syndrome. The evidence clearly indicates a temporary retardation in the rate of growth in weight and suggests a temporary slowing of growth in stature, but no effect on adult stature or weight. This temporary effect on growth is present during the first few years of treatment and seems related to drug dosage and to the presence or absence of drug holidays. These conclusions related specifically to treatment during the prepubertal period; little is known of the growth-related effects of treatment extending through pubescence.
