CT Has Nation's 11th Lowest Adult Obesity Rate, Survey Says
/One quarter of Connecticut’s adult population is obese, according to data compiled by Gallup, the 11th lowest rate in the nation. The state-by-state analysis indicates that at 18.5 percent, Hawaii has the lowest adult obesity rate in the U.S., closely followed by Colorado at 19.8 percent. They are the only two states in which the obesity rate is below 20 percent.
On the other end of the spectrum, West Virginia has the highest adult obesity rate, at 37.0 percent. In addition to West Virginia, at least one in three adults are obese in Mississippi, Delaware, Arkansas and Oklahoma. The obesity rate exceeds 30 percent in 18 states.
Of the 18 states with obesity rates of at least 30.0 percent, all but one are located in the South or Midwest. Meanwhile, all 11 states with obesity rates below 25.0 percent are located in the Northeast or West.
These data, from daily interviews conducted January through December 2015 as part of the Gallup-Healthways Well-Being Index, are based on U.S. adults' self-reports of their height and weight, which are then used to calculate Body Mass Index (BMI) scores. Americans who have a BMI of 30 or higher are classified as obese.
The national obesity rate reached a new high of 28.0 percent in 2015, up significantly from 25.5 percent in 2008, when Gallup and Healthways began tracking obesity. Fourteen states had statistically significant increases in their obesity rates from 2008 to 2015, while 
no state registered a statistically significant decline. Maine, West Virginia, Idaho and Oklahoma experienced the sharpest upticks in obesity.
Gallup calculated the incremental cost of healthcare per year for each state by multiplying the estimated number of obese people in the state's population by the annual incremental $1,573 cost of obesity per person.
In the five most obese states, the annual incremental cost of obesity per 100,000 residents averages $54 million. By contrast, the average cost is $34 million in the five least obese states. In other words, per capita medical costs attributable to obesity are about 1.6 times higher in the five states with the highest obesity rates than in the states with the five lowest rates. The cost in Connecticut for the obese adult population was estimated at $39 million, for the entire adult population, $1.07 billion.
