In a new study from Yonsei University, researchers found increased physical activity, including a low amount of light-intensity physical activity (LPA), is associated with a reduced risk for dementia among older adults.
They conducted a nationwide study involving 62,286 participants aged 65 years or older without dementia.
The researchers found that 3,757 participants (6.0%) developed dementia during a follow-up of 42 months, for an overall incidence of 21.6 per 1,000 person-years.
The risk for dementia was reduced for insufficiently active, active, and highly active participants compared with inactive individuals.
With increasing physical activity level, there was a decline observed in the ratio for dementia. This association started with a low amount of total physical.
The team found that even a low amount of physical activity was linked to reduced dementia risk compared with total sedentary behavior.
They suggest moving more during the day is linked to a lower risk of dementia. WHO’s guidelines about exercise suggest that:
Adults aged 18–64 years should do at least 150–300 minutes of moderate-intensity aerobic physical activity;
Or they should do at least 75–150 minutes of vigorous-intensity aerobic physical activity, or an equivalent combination of moderate- and vigorous-intensity activity throughout the week.
If you care about dementia risk, please read studies about if you control type 2 diabetes well, you may lower dementia risk, and findings that this MIND diet may protect your cognitive function, prevent dementia.
For more information about brain health, please see recent studies about common liver drug that may treat dementia effectively, and results showing that healthy lifestyle can reduce dementia even if you have a family history of the disease.
The study is published in JAMA Network Open. One author of the study is Minjae Yoon, M.D.
