Today, 6.4 million children between the ages of 4 and 17 - 11% of kids in this age group - have received an ADHD diagnosis, according to the study, which is based on a survey of parents. That's 2 million more children than in 2007.
The number of children using medications to treat ADHD is also rising. Since the last survey taken in 2007, there has been a 28% increase in children taking drugs to manage the disorder. More than 3.5 million children in the 4 to 17 age group, or 6%, are taking ADHD medications, the survey found.
These data are part of the CDC's National Survey of Children's Health, a national cross-sectional, randomized telephone survey. The survey is conducted every four years, and questions about ADHD diagnosis have been included since 2003. The latest data are from interviews conducted via telephone from February 2011 and June 2012, with 95,677 interviews completed and an overall response rate of 23%.
But while rising rates of ADHD diagnosis may be an alarming headline, Dr. John Walkup, director of child and adolescent psychiatry at Weill Cornell Medical College and New York-Presbyterian Hospital, found some positive news when looking at rates of prevalence and treatment. In his view, the data suggest that the increasing diagnosis rate of ADHD is getting closer to the true prevalence of ADHD, which is even higher.
"We've been working so hard for so long to improve treatment," Walkup said. "If the prevalence rate is 9 to 11% and we're getting 8% currently diagnosed, it suggests that the public advocacy for treatment is paying off."
