Abstract

Background: Declining physical performance in old age is associated with a wide range of negative health related outcomes, including disability, poor quality of life, admission to hospital, admission to residential care, and death (1 3). However, it is unclear which physical capabilities should be prioritized to obtain prognostic information in older adults. Methods: ilSIRENTE was a prospective cohort study of older adults residing in the mountain community of the Sirente geographic area in Central Italy. The study was designed by the Department of Geriatrics of the Università Cattolica del Sacro Cuore (Rome, Italy) an d the teaching nursing home Opera Santa Maria della Pace (Fontecchio, L’Aquila, Italy) in partnership with local administrators and primary care physicians of the Sirente Mountain Community Municipalities.
