Autism rates increase slightly: CDC

Abstract

The rates of autism in school‐aged children have increased slightly, from one in 68 children (1.5%) to one in 59 (1.7%), according to the federal Centers for Disease Control and Prevention (CDC). Published in the CDC's April 27 Morbidity and Mortality Weekly Report, the study of autism spectrum disorder (ASD) during 2014 is based on the Autism and Developmental Disabilities Monitoring (ADDM) Network, an active surveillance system. It provides estimates of the prevalence of ASD among children aged 8 years whose parents or guardians reside within Arizona, Arkansas, Colorado, Georgia, Maryland, Minnesota, Missouri, New Jersey, North Carolina, Tennessee and Wisconsin — the ADDM sites.
