AI Article Synopsis
- The study estimates that older adults, particularly those 75 and older, can gain additional years of life and healthy living through regular exercise based on data from the Cardiovascular Health Study.
- Physical activity was measured using a questionnaire, and the results showed that higher levels of exercise correspond to proportional increases in life expectancy and disability-free years, especially among seniors.
- The most active seniors (75+) reported significantly more healthy years of life compared to sedentary peers, with men seeing an increase of about 1.49 years and women about 1.06 years.
Article Abstract
Little is known about how many years of life and disability-free years seniors can gain through exercise. Using data from the Cardiovascular Health Study, the authors estimated the extra years of life and self-reported healthy life (over 11 years) and years without impairment in activities of daily living (over 6 years) associated with quintiles of physical activity (PA) in older adults from different age groups. They estimated PA from the Minnesota Leisure Time Activities Questionnaire. Multivariable linear regression adjusted for health-related covariates. The relative gains in survival and years of healthy life (YHL) generally were proportionate to the amount of PA, greater among those 75+, and higher in men. Compared with being sedentary, the most active men 75+ had 1.49 more YHL (95% CI: 0.79, 2.19), and the most active women 75+ had 1.06 more YHL (95% CI: 0.44, 1.68). Seniors over age 74 experience the largest relative gains in survival and healthy life from physical activity.
