The number of parent-reported diagnosed autism cases in the U.S. significantly increased, from 1 in 88 in 2007 to 1 in every 50 schoolchildren between 2011 and 2012, CDC researchers said. They looked at data from a national telephone survey and found that the increase was higher for boys and older children than girls and younger children. Experts said the higher numbers are likely a result of officials getting better at counting children with autism, rather than a true increase in prevalence.
