They studied the habits of 4,757 adults over the course of a week.Each participant wore an accelerometer, a small device fitted to the hip to measure how much time they spend walking and running.Their waist size, blood pressure and the level of C-reactive protein in their blood, which is often high in people at risk of heart disease, were also measured.
研究人員研究了4757個成人一周的工作習慣。每個參與者都在胯部佩戴了一個加速表，這個小裝置是用來測量被調查者每天用于走路和跑步的時間。研究人員還測量了參與者的腰圍、血壓以及血液中的C反應蛋白含量。一般心臟病患者的這些指標都很高。

The researchers, from the University of Queensland in Australia, whose study is published in the European Heart Journal, found that those who took the most breaks had waists up to 4cm smaller than those who were more sedentary.
