WASHINGTON (AP) — On Wednesday, Health Secretary Robert F. Kennedy Jr. introduced a plan aimed at leveraging medical data from Medicaid and Medicare recipients to investigate autism, though experts caution that this may not uncover the fundamental causes of the condition.
This initiative will establish a data-sharing partnership between the National Institutes of Health, the federal health research entity, and the Centers for Medicare and Medicaid Services, which holds claims data for nearly 150 million individuals nationwide.
“We’re using this partnership to uncover the root causes of autism and other chronic diseases,” Kennedy said in a statement.
The arrangement will adhere to relevant privacy laws to safeguard the sensitive health information of Americans, according to a statement from the HHS. The health department has not provided further details about the program in response to additional inquiries.
Using the data, the agency said researchers will focus on autism diagnosis trends, health outcomes from medical or behavioral treatment, access to care based on demographics and geography as well the economic burden of autism on families and health care systems.
The problem is that this isn’t the kind of data needed to answer questions about autism’s causes, said Helen Tager-Flusberg, professor emerita at Boston University who leads a new Coalition of Autism Scientists pushing back on Kennedy’s characterizations of the condition.
“Enough research has been done at this point to know there is no simple magic bullet,” she said, cautioning that this type of dataset won’t help with the type of research most needed — into genetics and other prenatal, preconception and early infancy factors.
Kennedy has directed the health department to undertake a far-reaching research effort to identify the causes of autism, a complex disorder that impacts the brain. Announcing his plans last month, Kennedy said he plans to provide answers as to what causes autism by September. He has since said the department will determine at least “some” of the causes.
His research directive comes as autism rates in the U.S. are rising, with the Centers for Disease Control and Prevention releasing a report that an estimated 1 in 31 U.S. children have autism, a marked increase from 2020. Scientists and researchers who study autism have said that increase in diagnoses is the result of increased awareness about the disorder, especially among people who exhibit milder symptoms of autism.
Kennedy has rejected that explanation in public appearances, instead describing autism as a “preventable disease” that is caused by environmental factors.
Autism is not considered a disease but a complex brain disorder. Those who have spent decades researching autism have found no single cause, although genetic factors are associated with it. In addition to genetics, scientists have identified various possible factors, including the age of a child’s father, the mother’s weight and whether she had diabetes or was exposed to certain chemicals.
Kennedy’s comments have sparked alarm among autism researchers and advocates, who fear he will use the study to support a discredited theory that vaccines cause autism. Kennedy, a longtime vaccine critic, has pushed that theory before, although decades of research has found no link between vaccines and autism. President Donald Trump has also suggested that vaccines could be to blame for autism rates.
The new platform that HHS plans to launch around autism will be a “pilot,” that will be used to study chronic conditions and treatments, the agency said.
