A new government survey once again ranks Kentucky among several states with very high obesity rates.Overall, more than a third of American adults are obese, but rates vary by location. The latest figures are based on a 2011 telephone survey that asked adults their height and weight. For the first time, households with only cell phones were included.The obesity rates for individual states remained about the same, but the number of states with rates that are considered “very high” jumped from 9 to 12. Kentucky is among those states, with about a 31 percent adult obesity rate.Colorado was lowest, at just under 21 percent, and Mississippi was highest at nearly 36 percent.Additional information from the Associated Press.
