Minority children with autism developmentally regress more
New research presented at the Pediatric Academic Societies annual meeting in May 2014 indicates that black and Hispanic children with autism tend to developmentally regress more often than white children with autism.
They define development regression in this case as loss of language, motor or social skills - usually after the child seemed to be developing normally for some time.
The study used medical (and demographic) info on 1,353 preschool-age children with autism in Canada and the U.S.
The researchers found that 27% of the children experienced developmental regress. Of those Hispanic children were 1.5 times more likely than white children to lose early skills, and black children were twice as likely to lose early skills than white children. And yes, the researchers controlled for things like insurance status and the caretaker's education.
I'd be curious if biracial children (like mine) would fall somewhere in between the black and white numbers.
Here's what I read:
