Scientists have ruled out a possible connection to autism. A study in this week's issue of British Medical Journal shows children with autism are no more likely than those without it to have had gastrointestinal problems as infants.
Study investigators from Boston University identified 90 children with autism and compared them to children without autism. They reviewed the children's medical histories, including when they had the measles, mumps, and rubella vaccination as well as if, and when, gastrointestinal problems may have started.
AdvertisementResearchers report no connection between colic, food allergies or gastrointestinal problems and autism. They also found no association between the time the child had the MMR vaccine and when the first signs of autism appeared. They write, "No evidence was found that children with autism were more likely than children without autism to have had defined gastrointestinal disorders at any time before their diagnosis of autism."
According this study the researchers say that this is consistent with other studies that have provided evidence against an association of gastrointestinal disorders and autism.
