There is no state in the U.S. where less than 20 percent of the adults are obese, the Centre for Disease Control and Prevention reported Thursday.
In four particular countries Alabama, Louisiana, Mississippi and West Virginia over 35 percent of surveyed adults were obese, the CDC said in a situate of newly released maps.
The maps indicate the prevalence of obesity among U.S. adults remains relatively high, despite nationwide efforts in recent years to boost families’ access to healthier foods and foster exert, Dr. Liping Pan, an epidemiologist in CDC’s Obesity Prevention and Control program, told Mashable .

“It’s still a public health problem, ” Dr. Pan said by phone.
Obesity can lead to health problems such as heart disease, stroke, Type 2 diabetes and specific types of cancer, according to CDC.
What counts as ‘obese’?
The CDC defines obesity as having a body mass indicator of 30 or higher.
Your BMI is your weight in kilograms divided by the square of your height in meters. A high BMI can indicate a high level of body fat, but it’s not a perfect science.
Critics of the BMI approach, including some doctors and researchers , note that the calculation can’t distinguish between fat and muscle. Your enormous biceps and rock-hard abs, for example, could pad your BMI measurement. And stick-thin adults may still have unhealthy high levels of fat that don’t register on the scale.
The agency based its adult obesity maps on self-reported data collected in hundreds of thousands of telephone interviews with U.S. adults. Survey respondents their height and weight, which the CDC used to calculate their individual BMI.
Dr. Pan said that, because the height and weight data was self-reported and not independently confirmed, the prevalence of adult obesity is likely higher than the CDC estimated.
“Women tend to under-report their weight, and some humen over-report their height, ” she said. Fudging those facts could skew a person’s BMI downward.
The CDC’s results on adult obesity tended to differ along racial lines.
About 38.1 percent of non-Hispanic black adults are deemed obese, according to CDC data from 2013 -2 015. Virtually 32 percentage of Hispanics and 27.6 percent of non-Hispanic whites are held obese.

Dr. Pan said a wide range of factors could account for the demographic changes, such as socioeconomic status, culture norms and access to grocery stores. “It’s a complex issue, ” she said.
She noted that survey sample sizes for Asians and other ethnic group were too small, so only three groups Hispanics , non-Hispanic blacks and non-Hispanic whites were included in the maps.
Pamela Bryant, a health communications specialist at CDC in Atlanta, said the goal of the maps is to “empower” individuals and policymakers to take steps to prevent obesity, such as by improving access to healthier, fresher foods and recreational alternatives in neighborhoods, schools and offices.
“We want to see our society being a place where people are moving more and eating better, ” she told Mashable . “We want that to become a societal norm.”
