31 U.S. states showed an increase in obesity rates over the previous year. The number of obese adults now exceeds 25 percent in 13 states.
Mississippi continued to be the "fattest" state, with 29.5 percent of adults there considered obese.
This is an increase of 1.1 percentage points from the year before. Nine of the 10 states with the highest levels of obesity are located in the South. West Virginia, the third heaviest state, also recorded the highest rate of type 2 diabetes, at 10.4 percent.
Colorado remained the thinnest state, with 16.9 percent of its adults considered obese. However, that is still also a slight increase. Only Nevada showed a decrease in the percentage of obese adults.
The results are associated with poverty rates. The five states with the highest obesity rates (Mississippi, Alabama, West Virginia, Louisiana and Kentucky) also have much higher poverty rates than the national norm. The five states with the lowest obesity (Colorado, Hawaii, Massachusetts, Rhode Island and Vermont) have relatively low poverty rates.
