Prevalence and functioning of children with cerebral palsy in four areas of the United States in 2006: A report from the Autism and Developmental Disabilities Monitoring Network

16 Feb

Most of what we hear (especially on this blog and other autism focused sources) about the Autism and Developmental Disabilities Monitoring Network (ADDM) is, well, autism related. Mostly we get the prevalence estimates for the CDC from this source. Sometimes I admit, I forget that “and Developmental Disabilities” is in there.

A recent paper shows that the ADDM is more broad than just autism. And, at the same time, gives some interesting autism information. The paper is: Prevalence and functioning of children with cerebral palsy in four areas of the United States in 2006: A report from the Autism and Developmental Disabilities Monitoring Network

Here is the abstract:

Abstract

AIM: To estimate the prevalence of cerebral palsy (CP) and the frequency of co-occurring developmental disabilities (DDs), gross motor function (GMF), and walking ability using the largest surveillance DD database in the US.

METHODS: We conducted population-based surveillance of 8-year-old children in 2006 (N=142,338), in areas of Alabama, Georgia, Wisconsin, and Missouri. This multi-site collaboration involved retrospective record review at multiple sources. We reported CP subtype, co-occurring DDs, Gross Motor Function Classification System (GMFCS) level, and walking ability as well as CP period prevalence by race/ethnicity and sex.

RESULTS: CP prevalence was 3.3 (95% confidence interval [CI]: 3.1-3.7) per 1000 and varied by site, ranging from 2.9 (Wisconsin) to 3.8 (Georgia) per 1000, 8-year olds (p<0.02). Approximately 81% had spastic CP. Among children with CP, 8% had an autism spectrum disorder and 35% had epilepsy. Using the GMFCS, 38.1% functioned at the highest level (I), with 17.1% at the lowest level (V). Fifty-six percent were able to walk independently and 33% had limited or no walking ability.

INTERPRETATION: Surveillance data are enhanced when factors such as functioning and co-occurring conditions known to affect clinical service needs, quality of life, and health care are also considered.

I will admit that I did not know that the prevalence of ASD amongst those with cerebral palsey was so high, 8%. It is interesting to note that there is a geographic variation in the prevalence estimates of CP, from 2.9 to 3.8 per 1000. This is not quite as large as the spread in autism prevalence estimates by state, but it is pretty big.
