CDC Reports U.S. Autism Rate Unchanged

A new report released Thursday from the Centers for Disease Control and Prevention (CDC) finds the prevalence of autism spectrum disorder (ASD) largely unchanged from two years ago, at one in 68 children. Researchers at the Johns Hopkins Bloomberg School of Public Health contributed to the study, which showed boys were 4.5 times more likely to be identified with ASD than girls. The rate is one in 42 among boys and one in 189 among girls.

This is the sixth report by the CDC’s Autism and Developmental Disabilities Monitoring Network (ADDM), which has used the same surveillance methods for more than a decade, a tracking system that provides estimates of the prevalence and characteristics of autism among 8-year-old children in 11 communities.

Here are the estimated prevalence rates of ASD in the U.S. reported by previous data:

  • one in 68 children in the 2014 report that looked at 2010 data
  • one in 88 children in the 2012 report that looked at 2008 data
  • one in 110 children in the 2009 report that looked at 2006 data
  • one in 150 children in the 2007 report that looked at 2000 and 2002 data

According to John Hopkins Bloomberg School of Public Health, researchers say it is too early to tell if the overall prevalence rate has stabilized because the numbers vary widely across ADDM communities. The school goes on to say that "the causes of autism are not completely understood; studies show that both environment and genetics may play a role. There is no known cure, and no treatment or intervention has been proven to reduce the prevalence of ASD."

Alison Singer, president of the Autism Science Foundation and mother of a daughter with autism, told CNN that this new report is not a sign everything is fine. "It points to the need for more research to understand nuances in data to be able to better serve all children diagnosed with autism," she said. The report suggests there are delays in acting on early concerns, said Rice.

Rice attributed the lack of early identification to a "capacity crisis." "There are not enough quality providers out there to provide those therapy services that are needed," she said. "I think a huge thing we need to do at the early age and across the life span of people with autism is ... identify and support individuals with autism."

Robert F. Kennedy, Jr., environmental lawyer and founder of The Mercury Project, finds the leveling off of the prevalence of autism to coincide with the decline of thimerosal in three childhood vaccines.

"Interestingly, this represents the first group of children that were not exposed to thimerosal through the HepB, HiB and DTaP infant vaccines," Kennedy said. "Also, uptake of the maternal flu vaccine was below 50 percent​. This is the first time essentially on record that autism rates haven't gone up since 1989."

New autism rate from the Center for Disease Control shows that autism began to flatline with the phase out of thimerosal from childhood vaccines.

Brian Hooker, associate professor of biology at Simpson University, agrees. He told EcoWatch:

"I'm not surprised that the autism numbers started to stabilize between birth years 2002 and 2004. By 2004, all of the back stock of thimerosal containing HepB, DTaP and HiB vaccines (which were no longer manufactured after 2001) would have been removed from the shelves and these infants (reflected in the latest CDC numbers) did not receive thimerosal in any of their vaccines, with the exception of the flu shot which was administered maternally and at 6 and 7 months of age. Flu shot uptake maternally and in infants was fairly low at this time but has increased since 2004.

"In Denmark, when thimerosal was phased out of infant vaccines in 1992, rates of autism spectrum disorder prevalence slowly dropped over 33 percent over the next 10 years. Unfortunately, because of the thimerosal-containing maternal flu shot, I don't think we'll see this profound of a drop in the U.S."

Regardless of the reason why the results of the new CDC study show the rate of autism unchanged, the American Academy of Pediatrics recommends that all kids are screened for autism at ages 18 and 24 months.
