| A new study estimates the prevalence of autism spectrum disorder at 3.14% among children and adolescents in the United States in 2019 and 2020, a rising trend. The study, published online Tuesday in JAMA Pediatrics, said this finding, derived from nationally representative data in the United States, was higher than the reported prevalence of the disorder from other surveys. Those included the National Health Interview Survey in 2014 to 2016 (2.47%), the Centers for Disease Control and Prevention’s Autism and Developmental Disabilities Monitoring Network in 2018 (2.30%) and the National Survey of Children’s Health in 2016 (2.50%). Researchers described the disorder as “a complicated neurodevelopmental disability with an increasing prevalence worldwide.” |
