If you work at home and spend the day sitting in front of a computer terminal, listen up.

A new study from the American Cancer Society found that time spent sitting is directly related to risk of death, and it’s worse if you don’t get some exercise. The study  is available online at the American Journal of Epidemiology.

Women who reported that they spent more than six hours per day sitting were 37 percent more likely to die during the time period studied (1993-2006) than those who sat fewer than 3 hours a day. Men who sat more than 6 hours a day were 18 percent more likely to die than those who sat fewer than 3 hours per day.

When combined with a lack of physical activity, the correlation was even stronger. Women and men who sat more and were less physically active were 94% and 48% more likely, respectively, to die compared with those who reported sitting the least and being most active.

Prolonged sitting, independent of physical activity, has been shown to have negative metabolic consequences, and may influence  triglycerides, high density lipoprotein, cholesterol, fasting plasma glucose, resting blood pressure, and leptin–all biomarkers of obesity and cardiovascular diseases.
