A groundbreaking study conducted by a US research team has revealed that sedentary behavior, such as sitting for extended periods of time, significantly increases the risk of dementia in older adults. The study, led by Professor David Raichlen from the Department of Biological Sciences at the University of California, followed the lifestyle habits of over 50,000 adults recorded in the UK Biobank.
The findings of the survey unveiled a shocking correlation between sedentary behavior and dementia. It was discovered that for every additional hour of sitting, the risk of developing dementia increased. Sitting for 10 hours a day raised the risk by 8%, while sitting for 12 hours surged the risk by a concerning 63%. The most alarming revelation came with the statistic that individuals who recorded 15 hours of sedentary behavior daily had over three times the risk of dementia.
Professor Raichlen explained, “Our study found that the total amount of time spent sitting each day, rather than the specific sitting behavior, was associated with an elevated risk of dementia.” He added, “Given that the average American spends 9.5 hours per day sitting, this is an issue of great concern.”
While the study could not establish a direct causal relationship between sedentary behavior and dementia, Professor Raichlen emphasized the importance of reducing sitting time and increasing physical activity to mitigate the risk. “Although our analysis does not allow us to draw definitive conclusions, decreasing sedentary behavior and engaging in more movement could potentially lower the likelihood of developing dementia,” he said.
The research team analyzed data from 49,841 adults aged 60 and over who wore exercise monitoring devices as part of the UK Biobank study. None of the participants had a history of dementia when they began wearing the monitoring devices, but over the course of an average 6.72 years, 414 individuals were subsequently diagnosed with dementia.
Using machine-based learning, the team determined sedentary time based on accelerometer readings, excluding sleep as a sedentary behavior. “Whether participants sat for a continuous 10 hours or sat intermittently throughout the day for a total of 10 hours, the risk of dementia remained high,” the research team revealed. Additionally, they found that watching television posed a greater risk than working on a computer.
The study’s results were published online in the prestigious medical journal JAMA, prompting experts and healthcare professionals to take note of the concerning relationship between sedentary behavior and dementia risk. As the research suggests, making an effort to incorporate more physical activity into daily routines could prove crucial in the fight against dementia.

The US research team followed 50,000 adults in Britain… It is more than three times higher when sedentary behavior occurs for 15 hours a day.
More dangerous than watching TV or using a computer… Sleep and sedentary behavior are not included
It was found that if an elderly person is sedentary for 15 hours a day, the risk of dementia is more than three times higher.
A new study has shown that the longer the elderly spend sitting doing daily activities such as watching TV or reading, the greater the risk of developing dementia.
Professor David Raichlen’s team from the Department of Biological Sciences at the University of California followed the lifestyle habits of over 50,000 adults recorded in the UK Biobank.
The results of the survey showed that if you sit for 10 hours a day, the risk of dementia increases by 8%, and if you sit for 12 hours a day, the risk of dementia increases by 63%. People who recorded 15 hours of sedentary behavior a day had a more than three times higher risk of dementia.
Professor Raichlen said, “The total amount of time spent sitting each day, rather than the amount or type of sitting behavior, was found to be associated with dementia,” and added, “Given that Americans spend 9.5 hours per day on average sitting, this is quite worrying.”
“Our analysis does not allow us to determine whether there is a causal relationship, so normative conclusions are not really possible,” he said. “However, sitting less and moving more could help reduce the risk of dementia.”
This study analyzed data collected by the UK Biobank on 49,841 adults aged 60 and over who wore exercise monitoring devices. The participants had no history of dementia when they wore the exercise monitoring devices, and 414 had been diagnosed with dementia over an average of 6.72 years.
The research team used machine-based learning to determine sedentary time based on accelerometer readings. Sleep was not included as sedentary behaviour. 414 participants were diagnosed with dementia over an average of 6.72 years.
“Whether the participants sat continuously for 10 hours or sat several times during the day for a total of 10 hours, the risk of dementia was high,” said the research team. “We found that watching television was associated with a higher risk of dementia in older adults than working on a computer.” he said.
The results of this study were published online on the 12th in JAMA, the journal of the American Medical Association.
