Prevalence of Autism (ASD) Among Children in the US (2007)

Good Morning.  I believe today will be a perfect day here is south Florida.  Morning temp is 60 degrees which means the afternoon should be in the mid 70s.  Thanksgiving was great.  I definitely had an l-tryptophan crash after eating all that turkey.  My NY Jets play later on vs. Carolina Panthers.  Maybe I’ll find something else to do.  Actually there is a “real” pirate ship docked at Peanut Island, The HMS Bounty.  I’d like to take my little buccaneer on their tour.  Anyway just a quickie today as a colleague of mine, Dr. Dan Murphy forwarded me this very interesting article on autism.  My last entry was also about autism or autism spectrum disorder and omega-3 fatty acid supplementation.  This article is from the journal, Pediatrics, volume 124, number 4, October 2009.  The authors are Michael D Kogan PhD, Stephen J Blumberg PhD, Laura A Schieve PhD, Coleen A Boyle PhD, James M Perrin MD, Reem m Ghandour DrPH, Gopal K Singh PhD, Bonnie B Strickland PhD, Edwin Trevathan MD MPH and Peter C van Dyck MD MPH


WHAT’S KNOWN ON THIS SUBJECT:  Numerous studies have suggested that the prevalence of diagnosed ASD in the United States has increased dramatically in past decades.

WHAT THIS STUDY ADDS:  Based on a recent national survey with parents of children aged 3 to 17 years, the point prevelance of diagnosed ASD is higher than previous US estimates.

METHODS: The prevelance of parent-reported diagnosis of ASD among US children aged 3 to 17 years was estimated from the 2007 National Children’s Health (sample size 78,037).

A child was considered to have ASD if a parent / guardian reported that a doctor or other health care provider had ever said that the child had ASD and that the child currently had the condition.  The point-prevalence for ASD was calculated for those children meeting both criteria.

RESULTS: The weighted current ASD point prevelance was 110 per 10,000.  (1 IN EVERY 91 CHILDREN) 673,000 US children were estimated to have ASD.  Odds of having ASD were 4 times as large for boys than girls.  Non-Hispanic (NH) black and multiracial children had lower odds tha NH white children.

Here’s some other interesting notes made by these authors:

  • Autism spectrum disorder (ASD) is a group of neurodevelopmental disorders.  Children who have ASD exhibit characteristic impairments in social interactions and communication and restricted, repetitive and stereotyped patterns of behavior
  • The lifetime healthcare costs for a person with autism have been estimated to be more than $1.6 million and the estimated total expense burden to the health care system associated with ASD rose 142% from 2000 to 2004
Published estimates of the reported prevalence of autism:
1960 – 1980………………………………………………1 in 2,000 to 1 in 5,000 US children
early 2000s……………………………………………..1 in 166 to 1 in 333 US children
2008 estimate…………………………………………..1 in 151 US children
And this study suggests ………………………………1 in 91 US children
Amazing.  I certainly do not have all or even many answers to this , but I will continue to forward any information I come across.  Obviously earlier and more aggressive educational and behavioral intervention is needed.  Once again omega-3 fatty acid fish oil supplementation seems to be helpful.  I will also try to find an older article relating television viewing to ASD.  Pure Encapsulations, Nutra-West and Nordic Naturals all have chewable fish oil capsules.  They actually taste good.  Anyway…thanks for reading this.  I have 59 followers of this blog.  Thank You!  I’m off to the pirate ship.  I’ll Tivo the Jets game…  moseschiropractic.com…. chiropractorwestpalmbeach.net.
