Effects of the times in front of the television and computer
Adults often spend a large part of their free time sitting in front of a computer or televisionwhat impact on that dementia risk Has. The risk increases with TV time, while time in front of the computer tends to reduce the probability of developing dementia.
In a recent prospective cohort study involving experts from the University of Southern California, Los Angeles It was investigated whether sedentary behavior with a lot of time sitting is associated with dementia regardless of physical activity. The results can be found in the journal “Proceedings of the National Academy of Sciences“ (PNAS) can be read.
Participants reported on leisure activities
The team examined 146,651 participants in the UK Biobankwho are at least an age of 60 years had and did not suffer from dementia.
The researchers divided the leisure activities reported by the participants themselves into two areas: Time spent in front of the television (cognitive passive), and time a computer was used (cognitively active).
Watching television increases the risk of dementia
at total 3.507 Participants then received a mean follow-up after 11.87 years dementia diagnosed.
After cleaning for a variety of covariates, including those with physical activity time spent watching TV was with one increased risk linked to the onset of dementia, the team said.
Time in front of the computer reduces risk of dementia
On the other hand, it turned out that the use of a computer the time spent sitting with one reduced risk was linked to the occurrence of dementia, the researchers continue to report.
These effects persisted even when factors such as physical activity were included.
Chronic diseases caused by television and computers
Sitting a lot in front of the computer or television is generally associated with an increased risk of chronic diseases and mortality linked, explain the experts. However, when it comes to a link between dementia and sedentary inactive behavior, it is more relevant whether the occupation is sedentary cognitively passive or cognitively active fails.
New targets identified to fight dementia
The results suggest, according to the researchers, that reducing cognitively passive sedentary time (i.e., TV time) and increasing cognitively active sedentary time (i.e., computer time) may be beneficial effective targets for behavior change to the Reducing the risk of dementia represent. (as)
