Prevalence of obesity among adults aged 20 and over in the U.S. from 1997 to 2018

by John Elflein, last edited Aug 9, 2019
Obesity prevalence among U.S. adults aged 20 and over 1997-2018 The prevalence of obesity in the United States has risen gradually over the past few decades. As of 2018, almost 32 percent of the population aged 20 years and older was obese. Obesity is a growing problem in many parts of the world but is particularly troubling in the United States.
Obesity in the United States

The states with the highest prevalence of obesity are West Virginia, Mississippi, Oklahoma, and Iowa. As of 2018, a shocking 38 percent of the population in West Virginia were obese. Obesity is more prevalent among women than men and is least prevalent among those aged 20 to 39 years. The percentage of adults aged 65 years and older who are obese has grown in recent years, compounding health issues that develop with age.

Health impacts of obesity

Obesity is linked to several negative health impacts including cardiovascular disease, diabetes, and certain types of cancer. Unsurprisingly, the prevalence of diagnosed diabetes has increased in the United States over the years. As of 2017, around 9.4 percent of the population had been diagnosed with diabetes. Some of the most common types of cancers caused by obesity include breast cancer in postmenopausal women, colon and rectum cancer, and endometrium cancer.
