Women who are physically active at any point over their life have lower risk of cognitive
impairment in late-life compared to those who are inactive, but teenage
physical activity appears to be most important, according to the Journal of the American Geriatrics Society.
There is growing evidence that people who are physically
active in mid- and late life have lower chance of dementia and more
minor forms of cognitive impairment in old age. Early life physical activity
and the relative importance of physical activity at different ages has not been studied as much.
Researchers led by Laura Middleton, PhD, of Sunnybrook Health Sciences Centre, Canada, compared the physical activity at teenage, age 30, age 50, and late life against cognition of 9,344 women from Maryland, Minnesota, Oregon and Pennsylvania to investigate the effectiveness of activity at different life stages.
Researchers led by Laura Middleton, PhD, of Sunnybrook Health Sciences Centre, Canada, compared the physical activity at teenage, age 30, age 50, and late life against cognition of 9,344 women from Maryland, Minnesota, Oregon and Pennsylvania to investigate the effectiveness of activity at different life stages.
Of the participants, 15.5%, 29.7%, 28.1%, and 21.1% reported being
physically inactive at teenage, at 30 years, at 50 years, and in late
life respectively.
When physical
activity measures for all four ages were entered into a single model
and adjusted for variables such as age, education, marital status,
diabetes, hypertension, depressive symptoms, smoking, and BMI, only
teenage physical activity status remained significantly associated with
cognitive performance in old age.
“Our study shows that women who are regularly physically active at
any age have lower risk of cognitive impairment than those who are
inactive but that being physically active at teenage is most important
in preventing cognitive impairment,” said Middleton.
The researchers also found that women who were physically inactive as
teenagers but became physically active at age 30 and age 50 had
significantly reduced odds of cognitive impairment relative to those who
remained physically inactive.
Middleton added, “As a result, to minimize the risk of dementia,
physical activity should be encouraged from early life. Not to be
without hope, people who were inactive at teenage can reduce their risk
of cognitive impairment by becoming active in later life.”
There is evidence to suggest that physical
activity has a positive effect on brain plasticity and cognition and in
addition, physical activity reduces the rates and severity of vascular
risk factors, such as hypertension, obesity, and type II diabetes, which
are each associated with increased risk of cognitive impairment.
Once again, our platform, educated aging - physical, emotional, financial - comes into play. Look through our hundreds of post and spot the word exercise. It's never to late to start a program.
