Frailty and physical activity: are all physical activity variables equal?

ABSTRACT:

Background

Frailty, defined as diminished physiological and functional reserve, is linked to negative health outcomes such as falls, fractures, and disability. Physical activity dose plays a significant role in preventing and reducing physical frailty, but the influence of different PA variables on deficit accumulation (ie, frailty index [FI]) is not fully understood.

Methods

We utilized Round 11 (2021) data from the National Health and Aging Trends Study, a longitudinal study of Medicare beneficiaries aged 65 and older in the United States.
