Another new study, involving 196,383 UK adults age 60 and older, has re-confirmed the importance of following healthy lifestyles for lowering your dementia risk — even if you have a high genetic risk for dementia. The study results showed a statistically significant difference: 1.13% of those with a healthy lifestyle developed dementia later in life compared with 1.78% of those with a less healthy lifestyle. The definition of healthy lifestyle included the following:
- avoid smoking tobacco
- be physically active
- drink alcohol in moderation, or not at all
- healthy diet: following recommendations on dietary priorities for cardiometabolic health
Here are three media articles on the study:
Your lifestyle can lower your dementia risk, even if you have high genetic risk, study says
Healthy lifestyle may offset genetic risk of dementia
Is healthy lifestyle associated with lower risk of dementia regardless of genetic risk?
The study was simultaneously presented at the 2019 Alzheimer’s Association International Conference together with JAMA publication here:
Association of Lifestyle and Genetic Risk With Incidence of Dementia
Another study presented at the Alzheimer’s Association Conference looked at similar issues. It tracked 2,765 individuals over about 10 years, rating them 1 point for maintaining each of the following healthy behaviors:
- a low-fat diet
- did not smoke
- exercised at least 150 minutes each week at moderate-to-vigorous levels
- drank moderately
- engaged in some late-life cognitive activities
Those who rated 4 or 5 (i.e., participated in 4 or 5 of the healthy behaviors) were were 60% less likely to develop Alzheimer’s compared with participants who rated only 0 or 1 (i.e. participated in none or one of the healthy behaviors). The results did not vary by race or gender.
Here are two media articles on the work (formal publication is not yet available):
