To 27% and 3% to 8%, respectively, across sites ( Table 5). Or motor areas) and plateau (lack of continued development without clear evidence of regression) in records ranged from 13% The percentage of children with indications of regression (loss of previously acquired skills in social, communication, play, (range: 52-56 months) across sites ( Table 5). The median age of earliest reported ASD diagnosis identified in the child's record was similar Documented developmental concerns with imaginative play were least common across all sites AcrossĪll sites, the most commonly documented early developmental concern was for language, followed by socialĬoncerns. The majority (69%-88%) of children with ASDs had documented developmental concerns before age 3 years. Of the children withĪSDs who had a cognitive or developmental IQ test result, the proportion of children with cognitive impairment (IQ ofĨ5) ranged from 17% in South Carolina to 39% in Arizona Had psychometric test results: Arizona with 90%, Georgia with 94%, and South Carolina with 89%. The exception of one surveillance site (Georgia), no statistically significant (p85% of children Overall prevalence of ASDs per 1,000 children aged 8 years ranged from 4.5 in West Virginia to 9.9 in New Jersey. Results: For 2000, across six sites, a total of 1,252 children aged 8 years were identified as having an ASD.
