Research adds heft to link between autism and obesity
Nearly half of American children with autism aged 10 to 17 are overweight or obese, compared with less than one-third of their typically developing peers, according to a new study1. And those with the most severe autism features appear to be at the greatest risk of being obese.
After controlling for race, ethnicity, income, age and sex, the researchers estimate that children with autism have 1.48 times the odds of being overweight, and 1.49 times the odds of being obese, compared with their typical peers.
Among autistic children, those with severe autism traits — based on parent reports — are more than three times as likely to be obese as those with milder traits. This subset of children may be at increased risk of obesity because they tend to be less active and have more restricted diets than other autistic children
