Those of you who work at a desk job all day--you could be at risk of heart disease, diabetes and obesity if you don't get up for a few minutes and move around.

That's the word from the University of Queensland in Australia that looked at 5,000 people who sit for long periods of time. They found that even if a person exercises regularly, they still had worse health than those who got up and took breaks. The study found, the more breaks the people took, the better their health was.

Dr. Genevieve Healy says you can do small things to get moving in the office. She suggests standing up to answer a telephone call to change your regular sitting routine.
