Montana claimed the title of least obese state in 2013, bumping Colorado out of the top spot, while Mississippi ranked as the most obese state, pushing out West Virginia, according to a Gallup-Healthways survey that questioned 178,000 adults about their height, weight and other issues related to personal health.
In 2013, Mississippi had an obesity rate of 35.4 percent, while the rate in Montana was 19.6 percent, the poll found. Montana was the only state with an obesity rate of less than 20 percent.
From 2010 to 2012, West Virginia ranked as the most obese state, and Colorado was the least obese. Mississippi has ranked among the most obese since 2008, according to Gallup-Healthways.
The national obesity rate rose again last year, from 26.2 percent in 2012 to 27.1 percent in 2013. Maryland and Virginia were in the middle of the pack. [See the complete list at www.gallup.com]
The states with the highest obesity rates tended to also have higher rates of chronic diseases, according to the report. For example, 35.8 percent of people in the 10 most obese states had high blood pressure, compared with 26.4 percent of Americans in the least obese states.
And people in states with the lowest obesity rates tended to have higher rates of healthful eating and exercise. For example, in the 10 least obese states, 66.7 percent of people said they ate healthy “all day yesterday,” compared with 60.8 percent of people in the 10 most obese states.
“Research has shown that the average health-care costs for an obese individual are over $1,300 more annually than [for] someone who is not obese,” James E. Pope, chief science officer at Healthways, a company based in Franklin, Tenn., said in a statement. “Although slowing, and even reversing, this trend may seem daunting, even modest weight loss of 5 percent to 10 percent of initial body weight can lower the health risks associated with obesity,” he said.
