(HealthDay News) – The number of obese adults remained constant at more than 78 million in the United States for 2011–2012, according to an October data brief published by the U.S. Centers for Disease Control and Prevention’s National Center for Health Statistics (NCHS).

Cynthia L. Ogden, PhD, from the NCHS in Hyattsville, MD, and colleagues utilized data from the National Health and Nutrition Examination Survey, 2011–2012, to calculate national estimates of obesity among adults, including among Asian adults for the first time.

The researchers found that, in 2011–2012, more than one-third (34.9%) of adults were obese, a number similar to 2009–2010. The prevalence of obesity was higher among middle-aged adults (39.5%), compared to younger (30.3%) or older (35.4%) adults. The prevalence did not differ between men and women, except in black adults where obesity was higher in women (56.6% for women vs. 37.1% for men). Overall, black adults had the highest prevalence of obesity (47.8%) and Asian adults had the lowest (10.8%), compared to Hispanics (42.5%) and white adults (32.6%).

“The most recent national data from 2011–2012 on obesity prevalence among U.S. adults show that there was no significant change since 2009–2010,” the authors write.
