According to a U.S. government study, the percentage of developmental disabilities in children within the United States has increased to just over 15%.
The study from the U.S. Centers for Disease Control and Prevention (CDC) found that developmental disorders increased from 12.84% in 1997 to 15.04% in 2008 for American children of the ages from three years to 17 years.
In other words, the increase in the numbers of developmental disabilities in U.S. children, taken from the 1997-2008 National Health Interview Surveys, went from 8 million to 10 million.
The authors of the study, led by Dr. Sheree Boule, from the National Center on Birth Defects and Developmental Disabilities, published their results in the journal
Pediatrics.
The paper's title is '
Trends in the Prevalence of Developmental Disabilities in US Children, 1997-2008.' It was published online on May 23, 2011 (doe: 10.1542/peds.2010-2989).
The authors looked at the following developmental disorders, as quoted from the abstract of their paper,
'attention deficit hyperactivity disorder; intellectual disability; cerebral palsy; autism; seizures; stuttering or stammering; moderate to profound hearing loss; blindness; learning disorders; and/or other developmental delays.' The authors stated,
'Autism, attention deficit hyperactivity disorder, and other developmental delays increased, whereas hearing loss showed a significant decline.'Page two concludes.
