Researchers at Johns Hopkins Bloomberg School of Public Health finds that ADHD children treated with stimulant medication initially have slower body mass index (BMI) growth than their untreated peers. BMI is a measure of body fat based on height and weight. But, that’s just the tip of the iceberg.

The researchers found that the slow growth of BMI was followed by a rapid rebound of BMI that was greater than that of children with no history of ADHD or stimulant medication use and that could continue to obesity.

The researchers found that the earlier the medication was given coupled with the longer the medication was taken resulted in slower BMI growth in earlier childhood but then the more rapid the BMI rebound in late adolescence, typically after medication was discontinued. Researchers concluded that stimulant use, and not a diagnosis of ADHD, was associated with higher BMI and obesity.

“Our findings should motivate greater attention to the possibility that longer-term stimulant use plays a role in the development of obesity in children,” said study lead, Prof . Brian Schwartz of Environmental Health Sciences, Epidemiology and Medicine at the Bloomberg School of Public Health. “Given the dramatic rise in ADHD diagnosis and stimulant treatment in recent decades, this is an interesting avenue of research regarding the childhood obesity epidemic, because the rises in each of these roughly parallel one another.”

Earlier research has noted decreased appetite and weight loss as being associated with stimulant medication use. This is the first comprehensive study to find low BMI rebounding to obesity even after discontinuation of the drug.

Many stimulants used to control ADHD symptoms were once used or initially invented as weight loss drugs.
