The U.S. Centers for Disease Control and Prevention (CDC) has released the latest data from the National Health and Nutrition Examination Survey showing that the age-adjusted prevalence of obesity was 42.4%, and the age-adjusted prevalence of severe obesity was 9.2% among adults aged 20 and over in the United States in 2017–2018. The U.S. adult population continues to move further away from the Healthy People 2020 goal of 30.5% obesity.

From 1999–2000 through 2017–2018, the prevalence of obesity and severe obesity increased, but the observed increase in the prevalence of obesity and severe obesity between 2015–2016 and 2017–2018 was not significant.

In 2017–2018, the overall prevalence of obesity was similar among men and women, but the prevalence of severe obesity was higher among women. Adults aged 40–59 had the highest prevalence of severe obesity.

The prevalence of obesity was highest among non-Hispanic black adults compared with other race and Hispanic-origin groups, overall and among women. However, among men, the prevalence of obesity was not significantly different between non-Hispanic white, non-Hispanic black, and Hispanic men. Overall, and among men and women, obesity was lowest among non-Hispanic Asian adults. Non-Hispanic black adults had the highest prevalence of severe obesity, and non-Hispanic Asian adults had the lowest.
