According to new research, published in the PLoS Med journal, populations that score high on standard heart health metrics in midlife significantly lower their risk of developing dementia in old age.
The paper was authored by a team at the Karolinska Institutet in Stockholm, Sweden.
A total of 1,449 participants were recruited from the Finnish Cardiovascular Risk Factors, Aging, and Dementia study.
“This cohort was followed from midlife (baseline from1972 to 1987; mean age 50.4 years; 62.1% female) to late life (1998), and then 744 dementia-free survivors were followed further into late life (2005 to 2008),” the authors wrote in the new paper. “We defined and scored global CVH metrics based on 6 of the 7 components (i.e., smoking, physical activity, and body mass index [BMI] as behavioral CVH metrics; fasting plasma glucose, total cholesterol, and blood pressure as biological CVH metrics) following the modified American Heart Association (AHA)’s recommendations.”
The researchers measured heart health from midlife to late-life via three behavioral factors (smoking status, physical activity, and body mass index) and three biological factors (fasting plasma glucose, total cholesterol, and blood pressure).
In the first follow-up, 61 people were diagnosed with dementia. In the second follow-up, 47 people developed dementia.
