ATLANTA (AP) -- Uncle Sam is watching your weight -- and finding that adult obesity rates in the U.S. seem to have leveled off at about 72 million people.
About 33 percent of adult men and 35 percent of women were obese in 2005-2006.
The survey by the Centers for Disease Control and Prevention found that the rates were slightly higher than the 31 and 33 percent reported in 2003-2004. Health officials do not consider the increases statistically significant.
The adult obesity rate has been climbing since 1980, when it was 15 percent.
The CDC says obesity is most common in adults aged 40 to 59. The study also found that about a third of obese adults had not been told by a doctor or health care provider that they were overweight.
