...HRSA survey in the journal Pediatrics. The survey - part of the 2007 National Survey of Children's Health - contained a number of intriguing data points. Most notable was the surprisingly high prevalence rate: one in 91 children ages 3 to 17 (1.1%) were described by parents as having an ASD diagnosis. Among boys, who are four times as likely to have autism as girls, the rate was 1 in 58. Even more mysterious, an additional group of children - 0.6% of the sample - were described by parents as having had an ASD diagnosis in the past, but suffered from...
...children who were diagnosed with autism, according to parents, no longer had the condition. It may be that such children received the autism label "to facilitate services for other conditions such as developmental delays," Kogan said. Or it could be that children were only tentatively classified as having ASD when they were very young and then the disorder was ruled out. (Read "Inside the Autistic Mind...
...parent survey indicated that autism is more commonly diagnosed among white non-Hispanics than other groups. African-American children were 57% less likely to be diagnosed with an ASD than whites; they were also more likely to be in the group that "lost" the diagnosis. Mild autism was the most common type reported by parents. Half of parents said their child had a mild form of ASD, one-third described the child's condition as "moderate" and the remaining 17% said their child was severely affected. Parents also indicated that nearly 9 out of 10 (87%) children with ASD also...
Experts not involved in the study caution that parent surveys are not the gold standard for measuring the prevalence of a medical condition. "The fact that 40% of the parents reporting that their child had received an ASD diagnosis now say the child no longer met criteria does suggest that there may be over-reporting in this survey," says Craig Newschaffer, a leading autism epidemiologist at Drexel University School of Public Health. "Nonetheless, the survey reinforces what we have come to understand over the past decade - that autism is much more common than previously thought." (See six tips for traveling...
...well with other, more rigorous studies finding a 1% rate of autism. "It provides what scientists call convergent validity: no matter how you shake the bushes, you come up with this 1%," says Richard Roy Grinker, an autism researcher at George Washington University who has worked to determine ASD prevalence in South Korea...
