NEW YORK — Obesity is still rising among American adults, despite more than a decade of public-awareness campaigns and other efforts to get people to watch their weight, and women have now overtaken men in the obese category, new government research shows.
For the past several years, experts thought the nation’s alarming, decades-long rise in obesity had leveled off. But the Centers for Disease Control and Prevention said in a report Thursday that the obesity rate climbed to nearly 38 percent of adults in 2013-14, up from 32 percent about a decade earlier.
“This is a striking finding” and suggests that a situation that was thought to be stable is getting worse, said Dr. William Dietz, an obesity expert at George Washington University.
But another authority, the University of North Carolina’s Barry Popkin, urged caution, saying the participants selected for the study may not have been representative of the nation as a whole.
Experts said they had no explanation for why the obesity rate appears to be rising.
The report also found a tipping of the scales toward women. Obesity rates for men and women had been roughly the same for about a decade. But in the new report, the rate was significantly higher for women, at 38 percent, compared with 34 percent for men.
Obesity — which means not merely overweight, but seriously overweight — is considered one of the nation’s leading public health problems. Until the early 1980s, only about 1 in 6 adults were obese, but the rate climbed dramatically until it hit about 1 in 3 around a decade ago.
The new figures come from a regular government survey that has about 5,000 participants each year. In interviews, people tend to understate their weight and overstate their height. But participants in this survey are actually weighed. Because of that, it is considered the gold standard for measuring the nation’s waistline.
The news comes after years of government anti-obesity campaigns to encourage people to eat better and exercise. Also, soda consumption has dropped in recent years, and fast-food chains have adopted healthier menus.
New federal rules have also been adopted to remove artificial trans fats from grocery store foods and to require chain restaurants to post calorie counts, though those have not gone into effect yet.
The widening gap between men and women seems to be driven by what’s happening among blacks and Hispanics, said the study’s lead author, the CDC’s Cynthia Ogden.
Obesity rates for white men and white women remain very close. But for blacks, the female obesity rate has soared to 57 percent, far above the male rate of 38 percent. The gender gap is widening among Hispanics, too — 46 percent for women, 39 percent for men.
The report also looked at obesity in children but did not see much change. For young people ages 2 to 19, the rate has been holding at about 17 percent over the past decade or so.
Health officials have been especially focused on obesity in kids, who are the target of the Let’s Move campaign launched by first lady Michelle Obama in 2010.
A CDC report last year noted one possible glimmer of hope: a decline in obesity among children ages 2 to 5. Their rate had fallen to about 8 percent in the 2011-12 survey, down from 14 per cent a decade earlier.
In a piece of good news, the new, 2013-14 report suggests that the decline among toddlers was real and not a statistical fluke. The rate was found to be holding pretty much steady around 9 percent.
The CDC measures obesity by calculating Body Mass Index, a ratio of weight to height. For adults, a BMI of 25 to 29.9 is overweight, and 30 or higher is obese. According to CDC definitions, a 5-foot-10 man is overweight at 174 pounds and obese at 209.
