Leicester, England – The risks of disease and death increase with long periods of sitting, even in otherwise active individuals, according to a new study from the University of Leicester.

The study combined results from 18 other studies and included nearly 800,000 participants. Results were independent of the amount of moderate or vigorous physical activity being done, meaning the health of active individuals could still be compromised if they sit for several hours a day.

Researchers concluded that people who sit for long periods have a twofold increase in the risk of diabetes, heart disease and death. In a press release, they recommended reducing sitting time by standing more often. This could include breaking up long periods at the computer by working on a laptop placed on a filing cabinet, conducting standing meetings, walking during lunch breaks, and avoiding sedentary behaviors during non-work hours.

The study was published in the November issue of the journal Diabetologia.
