CDC Reports Record Autism Rates, HHS Investigates Causes

The U.S. Centers for Disease Control and Prevention (CDC) reported a significant increase in autism spectrum disorder (ASD) diagnoses among children, with about 1 in 31 8-year-olds diagnosed in 2022, up from 1 in 36 in 2020. This rise is attributed to improved awareness, better diagnostic practices, and broader definitions of autism, rather than an increase in the actual incidence of the disorder. The CDC found variability in prevalence across different regions and demographics, noting higher rates among boys and certain racial and ethnic groups. Despite ongoing debates, including unfounded claims linking vaccines to autism, the increase is primarily explained by enhanced screening and early detection services. Efforts are underway to identify potential environmental and genetic factors contributing to autism, although current research emphasizes the genetic basis of the disorder. The U.S. Department of Health and Human Services and other stakeholders continue to investigate the causes behind rising autism rates.
