Adult obesity rates increased significantly in 37 states since last year, and declined only in the District of Columbia, according to the 2008 edition of a survey issued annually by the Trust for America's Health and the Robert Wood Johnson Foundation. More than 20% of adults are obese in every state except Colorado. Overall, the rate of childhood obesity has tripled since 1980, from 6.5% to 16.3%. An estimated two-thirds of American adults are now overweight; if the current trends continue, 75% of U.S. adults will be overweight or obese in just seven years. A person is defined as obese if they have a body mass index (a function of height and weight) of 30 or higher—someone who is 5 ft. 8 in. and weighs 200 lb, for instance, has a BMI of 30.4.
The survey found various reasons for the increase in weight, such as a rise in inactivity, as well as rising health problems that are thought to be linked to obesity, including an increase in type 2 diabetes, heart disease, and hypertension.
Following is a look at the 10 states with the highest obesity rates and the 10 states with the lowest rates.
