Adult obesity rates increased in 16 states in the past year and did not decline in any state, according to a new study from the Trust for America’s Health (TFAH) and the Robert Wood Johnson Foundation (RWJF).  Twelve states now have obesity rates above 30 percent. Four years ago, only one state was above 30 percent, according to the study.


The report, titled “Fas in Fat: How Obesity Threatens America’s Future 2011,” says the obesity epidemic continues to be most dramatic in the South, which includes nine of the 10 states with the highest adult obesity rates. States in the Northeast and West tend to have lower rates. Mississippi maintained the highest adult obesity rate for the seventh year in a row, and Colorado has the lowest obesity rate and is the only state with a rate under 20 percent.


This year, for the first time, the report examined how the obesity epidemic has grown over the past two decades. Twenty years ago, no state had an obesity rate above 15 percent.  Today, more than two out of three states – 38 total – have obesity rates over 25 percent, and just one has a rate lower than 20 percent.


Since 1995, obesity rates have doubled in seven states and increased by at least 90 percent in 10 others. Obesity rates have grown fastest in Oklahoma, Alabama, and Tennessee, and slowest in Washington, D.C., Colorado, and Connecticut.


“Today, the state with the lowest obesity rate would have had the highest rate in 1995,” said Jeff Levi, Ph.D., executive director of TFAH, in a statement. “There was a clear tipping point in our national weight gain over the last twenty years, and we cant afford to ignore the impact obesity has on our health and corresponding health care spending.”


The researchers said obesity has long been associated with other severe health problems, including diabetes and high blood pressure. New data in the report show how rates of both also have risen dramatically over the last two decades. Since 1995, diabetes rates have doubled in eight states. Then, only four states had diabetes rates above 6 percent.  Now, 43 states have diabetes rates over 7 percent, and 32 have rates above 8 percent. Twenty years ago, 37 states had hypertension rates over 20 percent. Now, every state is over 20 percent, with nine over 30 percent.


Racial and ethnic minority adults, and those with less education or who make less money, continue to have the highest overall obesity rates:


Among other findings, the report found that adult obesity rates for Blacks topped 40 percent in 15 states, 35 percent in 35 states, and 30 percent in 42 states and D.C.; rates of adult obesity among Latinos were above 35 percent in four states (Mississippi, North Dakota, South Carolina, and Texas) and at least 30 percent in 23 states; rates of adult obesity for Whites topped 30 percent in just four states (Kentucky, Mississippi, Tennessee, and West Virginia) and no state had a rate higher than 32.1 percent; nearly 33 percent of adults who did not graduate high school are obese, compared with 21.5 percent of those who graduated from college or technical college; more than 33 percent of adults who earn less than $15,000 per year were obese, compared with 24.6 percent of those who earn at least $50,000 per year.


“The information in this report should spur us all – individuals and policymakers alike – to redouble our efforts to reverse this debilitating and costly epidemic,” said Risa Lavizzo-Mourey, M.D., M.B.A, RWJF president and CEO. “Changing policies is an important way to provide children and families with vital resources and opportunities to make healthier choices easier in their day-to-day lives.”
