THE healthy lifestyle – proper nutrition, physical and mental exercise, etc. – is related to longer life expectancy but also with more years of life without Alzheimer’s for both men and women, a new US scientific study shows.
The researchers, led by him Assistant Professor Claudian Dana of the Department of Medicine, Ras University of Chicagowho published the relevant article in the British Medical Journal (BMJ), analyzed data on 2,449 people over 65 years (average age 76 years) without a history of dementia. A healthy living score was calculated for each based on detailed questionnaires for diet τους, τη physical activity their, the smokingthe alcohol consumptionand other activities that activate the mind (reading, crossword puzzles, visits to museums, etc.).
It was found that at the age of 65 the life expectancy was on average 24.2 years for women and 23.1 for men who lived the healthiest life and had the highest “score”. Unlike for women and men with worst rating due to more unhealthy lifestyle their life expectancy was considerably lower, at 21.1 and 17.4 years, respectively.
For women and men with a very healthy lifestyleof the rest of their lives, on average 10.8% (2.6 years) and 6.1% (1.4 years) respectively had to live with Alzheimer’s disease, compared to a longer period of 19, 3% (4.1 years) and 12% (2.1 years) of people with an unhealthy life. At the age of 85, the “gap” between those who lived healthy and unhealthy lives was even greater in terms of how much of the rest of their lives they would have to live with Alzheimer’s.
The number of people with Alzheimer’s disease and other forms of dementia is expected to tripled worldwide by 2050, from about 57 million in 2019 to 152 million. The more advanced the age, the greater the risk of Alzheimer’s. A healthy lifestyle can slow down the onset of dementia, but on the other hand it could also increase life expectancy with Alzheimer’s. However, it seems, according to the researchers, that “the expectation of a longer life, thanks to a healthy lifestyle, is not accompanied by an increased number of years of living with Alzheimer’s”.
