Autism prevalence is now estimated at 1 in 40 American children, the study says

In other words, the condition was reported in 2.5% of the children, which corresponds to approximately 1.5 million children between the ages of 3-17.

A report released this year by the US Center for Disease Control and Prevention measures estimated the prevalence of one in 59 children or about 1.7%, based on 2014 data.

“Prevalence does not grow so fast, even though CDC data suggests it is still growing,” said Thomas Frazier, chief executive officer of Autism Speaks, an e-mailed statement. He was not involved in the new report.

“What happens is that these studies use methods that are a bit more liberal and inclusive than CDC’s methods,” says Frazier, adding that he prefers the CDC’s number, but understands that “they are probably a bit conservative.”

The new study is based on the 201

6 National Survey of Children’s Health, conducted by the US Census Bureau, which collected information from parents of more than 50,000 children up to age 17. To be considered, parents would have reported that their children had ever been diagnosed with autism spectrum disorders and that they currently had the condition.

The new figures were also slightly lower than those made in the 2017 National Health Interview Survey. It was estimated that 2.76% of the children had ever received such a diagnosis, as the authors of the new report noted a wider definition.

The new study is based on parental reporting – which is not validated by health and education discs, as in the CDC report, can be a limitation despite the scope of research, says the authors.

Frazier said that the 1-in-40 figure is “generally consistent with previous parental studies and other direct prevalence studies where researchers directly screen and try to identify autism.”

The parents in the new study also reported more difficulty in getting care homes that their children need compared to those with Down’s syndrome or other behavioral disorder, such as hyperactivity in attention deficit “19659006” Although we have seen progress in recent years, this confirms what we know from our parents – that many children face unacceptable delays to get a diagnostic evaluation, even after parents, teak herself or other caregivers have recognized the signs of autism, says Frazier.

 Autism Prevalence Increases: 1 of 59 American Children


In the new study, a quarter of children with autism spectrum disorder took medication for symptoms related to the condition and Nearly two-thirds have been given “behavioral treatments” in the past year, the study says.

It also found a higher incidence of autism spectrum disorder among certain groups, such as boys, single and household children under the federal poverty rate, compared with the at least four times higher than the income ratio.

The differences between the new study number and the CDC study can be explained by the years they were conducted, the children’s ages studied and where they lived, according to the new study.

The CDC report was based on data collected from 11 communities across the country, but was not necessarily nationally representative, according to the report’s co-authors Daisy Christensen led the development team of the CDC’s National Center for Nursing and Developmental Disabilities.

“Parents Know Their Best Child,” Christensen, who was not involved in the new report, told CNN earlier. “We want to encourage parents to be aware of their children’s development, to be aware of the milestones that children achieve.”

Autism spectrum disorder, a lifelong development disorder, is characterized by communication and social interaction problems with accompanying repetitive behavioral patterns.

The authors note that it is difficult to compare the new report with previous iterations due to updates of how the survey collected its tasks and how questions were formulated.

“We can not tell what percentage was explained by internal investigation changes, rather than external factors,” the authors wrote.

Nevertheless, the report will show that the estimated occurrence of the disturbance has increased for decades.

“In the 80’s and 90’s, the diagnostic criteria were extended to include more children,” says Christensen, “so I think it is definitely an opportunity for the increase we have seen.”

Previously, more than half of children identified with autism had intellectual impairment, and now it’s about a third, she said. “And it’s really compatible with identifying children who may be in the milder end of the spectrum.”

The author of the new study also notes that universal screening recommendations in the 21st century may have led to increased prevalence among younger children, for example

“Since there is no biological marker, [autism spectrum disorder] is a particularly challenging condition to track, “the author’s note.

But understand how common it is that health experts can deploy resources and get families the help they need, according to Frazier.

“Having occurrence calculations – although there is some variation – helps us advocate for improved screening, diagnosis, interventions and support,” he said.
