SEATTLEâThe highest proportion of overweight and obese people â 13% of the global total â live in the United States, a country which accounts for only 5% of the worldâs population, according to a first-of-its-kind analysis of trend data from 188 countries.
Obesity rates have increased across the U.S. for both genders, all ages and ethnic groups; however, some groups are more severely affected than others. The prevalence of obesity among American adults was 35 percent in 2011 to 2012. However, among black Americans, the rate was 48 percent. The difference is even more striking among women, with 37 percent of all American compared to 57 percent of black American women classified as obese.
