Arizona: Older people who spend 10 hours or more per day sitting or being inactive may have an increased risk of developing dementia, a study has found.
In a study published in the journal JAMA, researchers examined data from more than 49,000 people aged 60 and over from the UK Biobank.
It doesn’t matter whether sitting for long periods of time or sitting intermittently throughout the day, both have similar effects on the risk of dementia, the researchers said.
However, the team said that less than 10 hours of inactivity was not associated with an increased risk of dementia, which is encouraging for office workers.
Jane Alexander, a professor of psychology and psychiatry at the University of Arizona and the Arizona Alzheimer’s Disease Research Center and the study’s author, said the researchers were surprised to find that more than 10 hours of inactivity per day increased the risk of dementia. Begin to grow rapidly, regardless of how many segments are completed this time.
He said the results of the study suggest that total time spent being inactive creates a link between lethargy and dementia risk, while less than 10 hours is not associated with additional risk.
