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
FROM ABSTRACT:
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
