US says 1 in 150 children have autism

 

 

 

 

Atlanta.– The largest U.S. Study of autism has found that the troubling condition is more common than previously understood.

About one in 150 American children has autism, U.S. Health officials said Thursday, calling the troubling disorder an urgent public health concern that is more common than they once thought.

The new numbers are based on the largest, most convincing study done so far in the United States, and trump previous estimates that placed the prevalence at 1 in 166.

The difference means roughly 50,000 more children and young adults may have autism and related disorders than was previously thought.

Government scientists declined to call the results a complete surprise: The new estimate is on the high end of a prevalence range identified in other recent studies, they said.

But one advocate said the study should cause policy-makers and the public to revise how they think of autism.

"This is a greater national health care crisis than we thought even yesterday," said Alison Singer, spokeswoman for Autism Speaks, the nation's largest organization advocating services for autistic children.

The study should fuel efforts to get the government to spend hundreds of millions of additional dollars for autism research and services.

"This data today show we're going to need more early intervention services and more therapists, and we're going to need federal and state legislators to stand up for these families," Singer said.

The study by the U.S. Centers for Disease Control and Prevention was based on 2002 data from 14 states. It calculated an average autism rate 6.6 per 1,000, compared to an estimate last year of 5.5 in 1,000.

The new research involved an intense review of medical and school records for children and gives the clearest picture yet of how common autism is in some parts of the country, CDC officials said.

The results suggest 560,000 children and young adults have the condition.

However, the study population is not demographically representative of the nation as a whole, so officials cautioned against using the results as a national average. The study doesn't include some of the most populous states, like California, Texas and Florida.

Also, the study does not answer whether autism has recently been on the rise – a controversial topic, driven in part by the contention of some parents and advocates that it is linked to a vaccine preservative. The best scientific studies have not borne out that claim.

"We can't make conclusions about trends yet," because the study's database is too new, said Catherine Rice, a CDC behavioral scientist who was the study's lead author.

Autism is a complex disorder usually not diagnosed in children until after age 3. It is characterized by a range of behaviors, including difficulty in expressing needs and inability to socialize. The cause is not known.

Scientists have been revising how common they think the disorder is. Past lower estimates were based on smaller studies. The study released Thursday is one of the first scientific papers to come out of a more authoritative way of measuring it.

"This is a more accurate rate because of the methods they used," said Dr. Eric Hollander, an autism expert at New York's Mount Sinai School of Medicine. The study involved 2002 data from parts or all of 14 states – Alabama, Arizona, Arkansas, Colorado, Georgia, Maryland, Missouri, New Jersey, North Carolina, Pennsylvania, South Carolina, Utah, West Virginia and Wisconsin.

Researchers looked specifically at children who were 8 years old because most autistic kids are diagnosed by that age.

The researchers checked health records in each area and school records when available, looking for children who met diagnostic criteria for autism. They used those numbers to calculate a prevalence rate for each study area.
