In the first study to look at objective measures of sedentary behavior and cancer mortality, researchers from The University of Texas MD Anderson Cancer Center found that greater inactivity was independently associated with a higher risk of dying from cancer.
The most sedentary individuals had an 82% higher risk of cancer mortality compared to the least sedentary individuals. An accelerometer was used to measure physical activity, rather than relying on participants to self-report their activity levels
“This is the first study that definitively shows a strong association between not moving and cancer death,” said Susan Gilchrist, M.D., associate professor of Clinical Cancer Prevention and lead author of the study, published today in JAMA Oncology. “Our findings show that the amount of time a person spends sitting prior to a cancer diagnosis is predictive of time to cancer death.”
