, the prevalence of autism in the United States remained relatively stable from 2014 to 2016, according to a new analysis. The results were recently published
.
report that the prevalence of autism in the United States was 2.24 percent in 2014, compared with 2.41 percent in 2015 and 2.76 percent in 2016. The new figures come from the National Health Visit Survey, an annual survey of trained statistics that asks hundreds of thousands of parents about their children's health. These questions include whether health care professionals have said their child has autism.
data, released by the U.S. Centers for Disease Control and Prevention (CDC), represent the highest prevalence of self-conditioning in the U.S. to date.
from this point of view, we can't see autism as an unusual condition, as people used to think. Wei Bao, an assistant professor of epidemiology at the University of Iowa and lead expert on the new study, said.
this spike may be due to data based on parental reports. These reports may include children with relatively mild autism, which is better than relying on medical records.
the past few decades, the incidence of autism in the United States has steadily increased. The researchers attribute this trend to how prevalence is measured, increased awareness of the condition in general, and changes in the criteria for diagnosing autism.
, an associate professor of psychiatry at the University of California who was not involved in the study, said the prevalence of autism worldwide appears to be between 2 and 3 percent.
the new incidence rate is consistent with the results of a 2011 study on autism in South Korea. The study showed that 2.64 percent of children in a South Korean school district had autism.
think we're saturated," he said. Kim, who led the study, said. No matter what research method is used, it will level off at that point. A
study by Kim and Kim in 2011 found a gender-related autism trait: a 3:1 prevalence ratio between boys and girls. The difference in results based on medical records is even greater: about 5:1. Kim says this suggests that girls with autism are sometimes overlooked. (Source: Science Network Feng Weiwei)
