Autism Rates Rise 30 Percent In Two-Year Span: CDC

CBS News – Autism in the United States remains on the rise, according to new government statistics.

One in 68 children have an autism spectrum disorder, according to the new numbers released Thursday from the Centers for Disease Control and Prevention. The statistics, collected in 2010 from 8-year-olds at 11 U.S. sites, reflect nearly a 30 percent rise in rates of the developmental disorder over the course of only two years.

“The number of children diagnosed with autism continues to rise” Dr. Coleen Boyle, director of CDC’s National Center on Birth Defects and Developmental Disabilities, told reporters during a Thursday press conference. “More is understood about autism than ever before, but these numbers are an important reminder for a need for answers.”

Autism spectrum disorders (ASDs) are a group of developmental issues that are shown to affect social, communication and behavioral functioning. The diagnosis includes milder forms of the disorder such as Asperger syndrome.

In May 2012, the last time the CDC released new autism numbers, 1 out of 88 children had the disorder based on data collected in 2008. At that time, the numbers represented a 25 percent raise from earlier figures of 1 in 110 U.S. children, suggesting a continual rise in the disorder in recent years.

The global prevalence of the disorder has increased between 20 and 30 times since the late 1960s and early 1970s, CDC researchers wrote in the new report, published March 27 in the CDC’s journal, Morbidity and Mortality Weekly Report.

“Behind each of these numbers is a person living with autism,” Liz Feld, president of the advocacy group Autism Speaks, said in a statement. “Autism is a pressing public health crisis that must be prioritized at the national level.”

The number of kids identified with an autism spectrum disorder in the new report ranged from 1 in 175 children in Alabama to 1 in 45 children in New Jersey, which Boyle explained may be a factor of differences in community resources for diagnosing and serving children.

The new data showed similar trends to previously-released reports: Autism remains almost five-times more common among boys than girls, affecting 1 in 42 boys versus 1 in 189 girls. Also, white children are more likely to be identified as having the disorder than are black or Hispanic children.

Minority children face major health care disparities with autism as they tend to be the last diagnosed, and the last to receive care.

Almost half of kids identified with ASD have average or above average intellectual ability — meaning an IQ above 85 — compared to one-third of children affected a decade ago. The CDC urged professionals to use these new data to ensure children with autism are getting the intervention and services they need to prosper.

“The most important thing for parents to do is to act early when there is a concern about a child’s development,” said Dr. Marshalyn Yeargin-Allsopp, chief of CDC’s Developmental Disabilities Branch. “If you have a concern about how your child plays, learns, speaks, acts, or moves, take action. Don’t wait.”

The CDC recommends parents “learn the signs. Act early,” by knowing thedevelopmental milestones children should reach from age 2 months to 5 years. Achecklist for parents can be found here.

The new report did not address causes of autism, which have remained elusive for health care professionals. Recent research looking at county rates of the disorder found evidence of environmental exposures to toxins like pesticides and lead may contribute to autism.

A study released March 26 in the New England Journal of Medicine found evidence autism may related to clusters of abnormal cells in areas of the brain that control for social, emotion, communication functions. The findings suggest thedisorder may start to develop in the womb.

Genetics mutations have also been identified as a risk factor.

The increased autism rates be a combination of increased awareness, better diagnosis by doctors and communities, and increased prevalence, said Boyle.

    Autism spectrum disorders are real, however I’d say 98% of the kids with “autism” have nothing more than a lack of discipline in the home.

    My son is autistic, but my other three children are not.

    The major differences between how they were raised is that my son sat in front of the t.v. from the time he was a new born.

    The other three simply had no interest in television.

    My son is 8 and he has a very short attention span and he is very impatient.

    I feel that he wired his brain this way from the fast changing television.

    While it may be true that ADHD, autism, panic attacks, anxiety, etc. are the newest fad disorders/diseases, but if you look closely at these new suffers, who will see nothing more than a person trying to get on disability.

    Yes I know I get just over $700 a month in SSI for my son, but I use 100% of that money to help him and I prove this every few years to Social security/SSI.

    If I could go back through time, I’d strictly of prohibited my son’s television intake.

    I have no doubt that his Autism was caused from t.v.

    My husband says all he needs is a good whipping, but I don’t believe in hurting a child for not minding.

    Sadly 98% of people diagnosed with the conditions above really don’t have it and the kids/people who really have the disorders can’t afford to get diagnosed and they are the ones who really need the help.

    This whole situation is sad.

    Autism rates started raising in the early 90’s. The same time that GMO products started being put in our food. Coincidence? I think not. Rats fed GMO’s also had an increased rate of birth defects.

    Vaccines and GMO’s are poisoning a generation of children, is it a wonder that almost everyone is refusing them.

    There is something going on and it is very sad. We did not see this to the extent it is now in my childhood.
