Some American See More Weight Gain Than Others

More Americans are overweight and obese than ever before, according to a new study from the Centers for Disease Control and Prevention. The study says that while people of all ages and races have gained weight in the last decade, some particular populations saw the biggest increases.

The problem of obesity is getting worse in the U.S. Now we know that one-third of adults are obese, and in the last two decades, overweight among children has tripled.

Dr. Cynthia Ogden and her colleagues at the Centers For Disease Control and Prevention studied more than 4,000 children and teens, and more than 4,000 adults across the U.S. The research shows that more americans are obese than ever before. But the biggest increases were found in four groups: people over age sixty, African American and Mexican American teens, and African American women.

There have been many suggestions as to why it's happening, including increase in portion sizes, eating out more, and the fact that we're very inactive and we don't get enough exercise.

Dr. Ogden says this is a public health crisis, because obesity can lead to a number of serious health problems, such as diabetes, heart disease and stroke. She also says the increase in obesity is alarming, and that individuals, families and communities must work together to solve this problem.

Dr. Ogden says these new obesity studies are more accurate than past studies, which relied on self-reporting.
