One Type of Sitting may Pose Greater Dementia Risk than Others, Study Suggests

For years, researchers have believed prolonged sitting could raise dementia risk — but new findings suggest the type of sitting may matter more than previously thought.

The research, which was published in the American Journal of Preventive Medicine in March, found that replacing mentally passive sedentary behavior with mentally active sedentary behavior was associated with a significant reduction in dementia risk.

Mentally active sedentary behaviors could include reading, office work and other activities that keep the brain engaged while sitting, while mentally passive behaviors may include watching television or other low-engagement screen activities.

To gather the findings, Swedish researchers analyzed data from more than 20,000 adults between ages 35 and 64 who were tracked over a 19-year period, between 1997 and 2016, according to a press release.

Participants answered questions about their sitting habits, physical activity and other lifestyle behaviors, while dementia diagnoses were identified using Swedish health and death records.

Mentally active sedentary behavior was associated with “a significant reduction in dementia risk” compared to more passive sitting activities. (Read more from “One Type of Sitting may Pose Greater Dementia Risk than Others, Study Suggests” HERE)
