Adult obesity rates now exceed 25 percent in 31 states and exceed 20 percent in 49 states and Washington, D.C. Two-thirds of American adults are either obese or overweight. In 1991, no state had an obesity rate above 20 percent. In 1980, the national average for adult obesity was 15 percent. Sixteen states experienced an increase for the second year in a row, and 11 states experienced an increase for the third straight year.
Eight of the 10 states with the highest rates of obese and overweight children are in the South. Childhood obesity rates have more than tripled since 1980.
"Reversing the childhood obesity epidemic is a critical ingredient for delivering a healthier population and making health reform work," said Risa Lavizzo-Mourey, M.D., M.B.A., RWJF president and CEO. "If we can prevent the current generation of young people from developing the serious and costly chronic conditions related to obesity, we can not only improve health and quality of life, but we can also save billions of dollars and make our health care systems more efficient and sustainable."
