NEW YORK, N.Y. - We Americans already know how fat we are. Can it get much worse?
Apparently, yes, according to an advocacy group that predicts that by 2030 more than half the people in the vast majority of states will be obese.
Mississippi is expected to retain its crown as the fattest state in the nation for at least two more decades. The report predicts 67 per cent of that state's adults will be obese by 2030; that would be an astounding increase from Mississippi's current 35 per cent obesity rate.
The new projections were released Tuesday by Trust for America's Health with funding from the Robert Wood Johnson Foundation. Trust for America's Health regularly reports on obesity to raise awareness, mostly relying on government figures.
The group's dismal forecast goes beyond the 42 per cent national obesity level that federal health officials project by 2030. The group predicts every state would have rates above 44 per cent by that time, although it didn't calculate an overall national average.
About two-thirds of Americans are overweight now. That includes those who are obese, a group that accounts for about 36 per cent. Obesity rates have been holding steady in recent years. Obesity is defined as having a body-mass index of 30 or more, a measure of weight for height.
Trust for America's Health officials said their projections are based in part on state-by-state surveys by the Centers for Disease Control and Prevention from 1999 through 2010. The phone surveys ask residents to self-report their height and weight; people aren't always so accurate about that.
The researchers then looked at other national data tracking residents' weight and measurements and made adjustments for how much people in each state might fudge the truth about their weight. They also tried to apply recent trends in obesity rates, along with other factors, to make the predictions.
Officials with Trust for America's Health said they believe their projections are reasonable.
And New York City's health commissioner agreed. "If we don't do anything, I think that's a fair prediction," said Dr. Thomas Farley whose city banned just supersize sugary drinks to curb obesity.
Trust for America projects that by 2030, 13 states would have adult obesity rates above 60 per cent, 39 states might have rates above 50 per cent, and every state would have rates above 44 per cent.
Even in the thinnest state — Colorado, where about one-fifth of residents are obese — 45 per cent would be obese by 2030.
Perhaps more surprising, Delaware is expected to have obesity levels nearly as high as Mississippi. Delaware currently is in the middle of the pack when it comes to self-reported obesity rates.
The report didn't detail why some states' rates were expected to jump more than others. It also didn't calculate an average adult obesity rate for the entire nation in 2030, as the CDC did a few months ago. But a researcher who worked on the Trust for America's Health study acknowledged that report's numbers point toward a figure close to 50 per cent.
CDC officials declined to comment on the new report.
Whichever estimates you trust most, it's clear that the nation's weight problem is going to continue, escalating the number of cases of diabetes, heart disease and stroke, said Jeff Levi, executive director of Trust for America's Health.
By 2030, medical costs from treating obesity-related diseases are likely to increase by $48 billion, to $66 billion per year, his report said.
The focus of so much of the ongoing debate about health care is over controlling costs, Levi said. "... We can only achieve it by addressing obesity. Otherwise, we're just tinkering around the margins."
