New research suggests that autism prevalence rose as much as 500% in recent decades, but it still may be underdiagnosed.
In an analysis of data on 8-year-olds in the New York-New Jersey metropolitan area between 2000 and 2016, researchers found that the number of children with autism and intellectual disability doubled over the time period. Among those without intellectual disability, however, the increase was fivefold.
Still, the study published online Thursday in the journal Pediatrics finds that disparities in diagnosis persist and many kids may remain overlooked. Children from affluent areas were 80% more likely than those from underserved areas to be flagged as having autism with no intellectual disability while Black children in this category were 30% less likely to be identified as compared to white kids.
