About
Previous NIH funded Attention Deficit Hyperactivity Disorder (ADHD) trials in children found that daily stimulant therapy produced sustained growth deficits. However, no federally funded studies have examined the growth suppression associated with modern once a day stimulant medications. Therefore, this study will precisely estimate the risks of stimulant induced growth suppression (SIGS), examine the underlying mechanisms and develop treatments for it. While drug holidays and caloric supplementation are two common treatments for SIGS, there has been little systematic investigation of either. It is unknown if they are effective or feasible. Therefore, using a randomized adaptive design, we will evaluate the efficacy and feasibility of these two practices vs. routine monitoring of growth in 180 prepubertal children with ADHD. An additional 50 subjects will be treated solely with behavioral therapies to evaluate for growth abnormalities associated with ADHD. The study will assess will the risk of SIGS with ER stimulants and the underlying mechanisms while providing evidenced-based treatments for its management.
Full description
The study will consist of 4 parts:
A) Extra monitoring: A doctor will check the child's growth every month (instead of every 3 months) until his/her BMI has returned to normal.The child will stay on the current daily dose of medication or behavior therapy.
B) Caloric supplementation: Parents will be provided with a flavored calorie drink to give to your child every night and continue on the same daily dose and frequency of medication or behavior therapy. The child will have their growth monitored monthly by a study doctor.
C) Drug Holiday: Participants will now only take medication on school days. Children assigned to behavior therapy will not participate in this treatment as they are not taking any study medication. The child will have their growth monitored monthly by a study doctor.
Once the child's weight recovers, these extra treatments will end and he/she will return to the prior medication treatment (medication7 days a week or behavior therapy) in step 3 and to every 3 month growth assessments. Any time the child's BMI declines again, the extra treatments will restart again.
