1 in 45 Children with Autism

1in45According to a new government estimate, about 1 in 45 children in the U.S. has autism. The estimate, which comes from researchers at the Center for Diseases Control and Prevention (CDC), is based on data collected during a yearly survey, from interviews of parents about their children, and is the first report of the prevalence of autism in the U.S. to include data from years 2011 to 2014.

While this looks like a substantial increase from the CDC’s last estimate, which was 1 in 68 children and just announced over the summer, the previous estimate was determined from a different survey that gathers information from children’s medical records and it was based on data collected during 2010.

The reason for this increase may not necessarily be that there are more children with autism than there have been in previous years—meaning, there’s likely no factors such as environmental conditions, etc. that can be causing the increase. Instead, the rate increases could be attributed to growing awareness of autism and more children being more appropriately diagnosed on the spectrum versus other conditions. The way in which data was collected and the questions that were asked of parents have also been restructured a bit, which may have also impacted the data collected. (read more about that here).

And while the 1 in 68 rate will still be treated as the best estimate, the newly reported number can be an indicator that the 1 in 68 is an underestimate.

Is Autism Really On the Rise?

Two new interesting studies have come out – one focused on the rate of autism and the other on a possible hormone that is linked with social difficulties.

The rate of autism has been continuously increasing over the years, with the latest figures showing that 1 in 68 children are diagnosed with autism. The rate increase hasn’t been attributed to anything specifically, and questions are mounting as to what has caused the increase. A new study, however, may have provided an answer – the rate is likely due to a change in the way children are being classified and diagnosed. A team from Penn State University looked at special education enrollment and found that the increase in students designated as having autism could be offset by nearly equal decrease in students diagnosed with other intellectual disabilities often seen along with autism. So conditions that were once likely classified as something else are now being identified as autism, probably due to broader awareness.

Another study showed that children with autism who struggle with “theory of mind” – the social skills that deals with the realization that other people have different perspectives, feelings and experiences – have lower vasopressin levels. Vasopressin is a hormone that helps regulate blood pressure and may play a role in social behavior. There are currently no medications that effectively treat social deficits, so this could prove a target for future focus.
