Over the last decade, an increasing number of American children have been diagnosed with attention-deficit hyperactivity disorder (ADHD), a new government survey reveals. Researchers from the U.S. Centers for Disease Control and Prevention found that between 2007 and 2009, an average of 9 percent of children between the ages of 5 and 17 were diagnosed with the disorder. This compared with just under 7 percent between 1998 and 2000.
The survey also indicated that previously notable racial differences in ADHD incidence rates have narrowed considerably since the turn of the millennium, with prevalence now comparable among whites, blacks and some Hispanic groups.
“We don’t have the data to say for certain what explains these patterns, but I would caution against concluding that what we have here is a real increase in the occurrence of this condition,” stressed study author Dr. Lara J. Akinbami, a medical officer with the National Center for Health Statistics. The findings appear in an Aug. 18 report from the agency.
