Prevalence of overweight and obesity among US youth with autism spectrum disorder

The purpose of this study was to examine current overweight and obesity prevalence rates among US youth (aged 10-17 years) with and without autism spectrum disorder, based on the 2016 National Survey of Children's Health. Analyses of weight status, derived from parent-reported height and weight measures, were conducted for a weighted sample of 875,963 youth with autism spectrum disorder and 31,913,657 typically developing youth. Controlling for age, race/ethnicity, income, and sex, youth with autism spectrum disorder had significantly higher odds of overweight (odds ratio = 1.48, p = 0.04) and obesity (odds ratio = 1.49, p = 0.02) compared to typically developing youth. Among youth with autism spectrum disorder, 19.4% were overweight and 23.05% were obese. Among typically developing youth, 14.9% were overweight and 15.91% were obese. Higher odds of obesity were reported for youth with severe autism spectrum disorder (odds ratio = 3.35, p < 0.01), compared to those with mild autism spectrum disorder.
