While previous research has found that physical exercise decreases fall risk and improves mobility, researchers at the Universidad Autónoma de Madrid (UAM) in Spain wondered whether physical activity could reduce frailty-associated mortality risk. In their study, published in the Journal of the American Geriatrics Society, authors found that physical activity decreased mortality rates for healthy, prefrail, and frail adults over age 60.
Authors used data from a nationally representative sample of 3,896 community-dwelling individuals to explore any “separate and joint associations between physical activity and frailty” and all-cause and cardiovascular disease (CVD) mortality rates.
At baseline, in 2000–2001, researchers interviewed participants at home about their “leisure-time” physical activity: inactive, occasional, several times a month, or several times a week. They administered both the Fatigue, Resistance, Ambulation, Illness, and weight Loss (FRAIL) scale and 3 items from the 36-item Short-Form Health Survey (SF-36) to measure frailty, fatigue, resistance, ambulation, and weight loss. Participants also were asked whether they had been diagnosed with pneumonia, asthma or chronic bronchitis, hypertension, coronary heart disease, stroke, osteoarthritis or rheumatism, diabetes mellitus, depression under drug treatment, hip fracture, Parkinson disease, or cancer.
