The Epidemiology and Societal Impact of Aging-Related Functional Limitations: A Looming Public Health Crisis

Functional impairment and disability become increasingly common with aging. As more people are reaching old age, the number of people needing care will rise, creating a crisis of need for care. Population studies and clinical trials have demonstrated the importance of the detection of early loss of strength and walking speed in predicting disability and in designing interventions to prevent functional decline. There is a large societal burden linked to age-related disorders. Physical activity is to date the only intervention that has prevented disability in a long-term clinical trial, but is difficult to sustain. Novel interventions are needed to maintain function in late life.

Functional impairment and disability are becoming more common among aging individuals, leading to an increasing need for care. Studies have shown that early detection of strength loss and walking speed decline is crucial in predicting disability and designing interventions to prevent functional decline. Age-related disorders pose a significant societal burden, and while physical activity has proven to be effective in preventing disability, sustaining it is challenging. Novel interventions are required to maintain function in late life.
