Obesity Among U.S. Adults Continues to Rise

More than 400,000 U.S. adults were surveyed in the 2008 BRFSS, which is the world’s largest telephone health survey. To assess obesity prevalence, survey respondents are asked to provide their height and weight, which is used to calculate their body mass index (BMI). A person is considered obese if they have a BMI of 30 or above.

“Obesity is a major risk factor for many chronic diseases such as heart disease and diabetes. As obesity increases among all age groups, we are seeing chronic diseases in much younger adults compared to a few decades ago,” said Dr. William Dietz, director, CDC’s Division of Nutrition, Physical Activity and Obesity.
“For example, we now see young adults who suffer from heart disease risk factors and other conditions such as type 2 diabetes that were unheard of in the past.”

The 2008 BRFSS obesity data indicate that none of the 50 states or the District of Columbia has achieved the Healthy People 2010 goal of reducing obesity prevalence to 15 percent or less.

“The latest BRFSS survey data show that the obesity problem in this country is getting worse,” said Liping Pan, CDC epidemiologist and lead author of the 2008 BRFSS obesity map analysis. “If this trend continues we will likely see increases in health care costs for obesity related diseases.”
