Too Much Sitting After 60 May Lead to Disability
Too much sitting has been linked to increased risk for health problems such as heart failure and earlier death. Now, a new study finds older adults who sit too much are more likely to be disabled -- regardless of their exercise habits.
"Sedentary behavior is its own separate risk factor [for disability]," said study researcher Dorothy Dunlop, a professor of medicine at the Northwestern University's Feinberg School of Medicine. She evaluated the exercise habits of more than 2,000 men and women, aged 60 and above, and their ability to perform normal everyday activities.
"Regardless of how much time they spent in moderate physical activity, the more time they spent being sedentary, the more likely they were to be disabled," Dunlop said.
However, another expert wonders if the relationship may occur in the opposite way -- that the more disabled people are, the more sedentary they are due to inability to exercise.
The study was supported in part by the U.S. National Institute for Arthritis and Musculoskeletal Diseases. It was published online Feb. 19 in the Journal of Physical Activity & Health.
Dunlop and her colleagues evaluated responses given to the U.S. National Health and Nutrition Examination Survey. The men and women answering the survey wore accelerometer devices to measure their activity on at least four different days between 2002 and 2005.
