Transcript for Fewer Household Chores May Lead to Weight Gain in Women
And now, we move onto a new report on obesity, with a surprising conclusion. Researchers say they have found a link between a woman's weight and the amount of work done around the home. Abc's cecilia vega takes a closer look tonight at a headline that is already drawing fire. Reporter: All that grueling housework? The homemaker walks miles every day.

Today, a third of all american adults are obese. 50 years ago, the number was fewer than 10%. And both sexes areanding at an equal pace. Proof that when it comes to growing waistlines, there may be eqty after all. Cecilia vega, abc news, los angeles.
