Examining the Skeletal Effects of Psychostimulants (H-47530)



Stimulant medications, like Ritalin, Concerta, Focalin, Vyvanse, or Adderall, are used to treat attention deficit hyperactivity disorder (ADHD). These medications are known to have an effect on growth in height. Our previous work shows that they may also have an effect on bone development and strength. As such, this study focuses on investigating the effect of these medications on bone quality and strength. We are enrolling children and teens between the ages of 7 and 16 years old who are planning to start a medication for attention or who have never experienced any psychiatric or mental health problems.  This study involves three clinic visits over the span of a year, monthly phone check-ins, collection of blood, saliva, urine, and stool samples, a physical exam, physical activity monitoring, questionnaires for both participants and the parents to complete, and bone scans. We provide compensation between $75 and $555, reimbursement for transportation expenses, a copy of the bone scan, and a meal. This study is funded by the National Institutes of Health.
