A new study found that increases in obesity and severe obesity prevalence have persisted among U.S. adults over the most recent decade, but adjusted linear trends among youth remained nonsignificant.

Results show that obesity among adults increased from 33.7% in 2007-2008 to 39.6% in 2015-2016. Prevalence of severe obesity in adults increased from 5.7% to 7.7%. The adjusted models also show significant overall linear trends for obesity and severe obesity among adults.

The study involved an analysis of data from the National Health and Nutrition Examination Survey. Results were published March 23 as a research letter in JAMA.
