University of South Carolina researchers have hit on an unusual reason for the growing rates of obesity among women, lack of house work.
The researchers said that women in 2010 spent just over half of the total time that women from 1965 spent doing house work and were 22 pounds heavier than their 1965 counterparts.
The researchers analyzed the activity logs kept by some stay-at-home women from 1965 and found that they spent around 25.7 hours a week doing house hold chores such as mopping, vacuuming, cooking and washing compared to 13.3 hours a week in 2010.
"We looked at 91 different activities — going to the gym, walking the dog — and the only thing that influenced their energy expenditure was the work in the home. That's why the study focused on that. The take-home message is not that women should be doing more housework but rather that women and individuals in general should find ways of integrating physical activity into their day", lead researcher Edward Archer said.
