Frailty, falls and poor functional mobility predict new onset of activity restriction due to concerns about falling in older adults

Copyright © The Author(s) 2023. Purpose: Concerns about falling are common in older adults and often cause activity restriction. This can lead to physical deconditioning, falls and social isolation. However, not every concerned older adult will restrict their activities. This 12-month longitudinal study investigated the physical and psychosocial factors that predict the new onset of activity restriction due to concerns about falling in older people. Methods: Participants were 543 older adults (Mage = 80.3 ± 4.4 years, range: 75–98) who did not report activity restriction due to concerns about falling at Timepoint-1 (negative response to the following question: “Do concerns about falling stop you going out-and-about?”). Participants completed a battery of physical and psychological assessments at Timepoint-1. Using binary logistic regression, we then assessed which of these variables predicted whether participants reported having started restricting their activity due to concerns about falling at the 12-month follow-up (Timepoint 2). Results: 10.1% of the sample started to restrict activity due to concerns about falling at Timepoint 2. Three key predictors significantly predicted activity restriction group status at 12-month follow-up: greater frailty at Timepoint-1 (Fried Frailty Index; OR = 1.58, 95% CI 1.09–2.30), experiencing a fall between Timepoint-1 and 2 (OR = 2.22, 95% CI 1.13–4.38) and poorer functional mobility at Timepoint-1 (Timed up and Go; OR = 1.08, 95% CI 1.01–1.15). Conclusions: Frailty, experiencing a fall and poorer functional mobility all predicted the onset of activity restriction due to concerns about falling. Clinicians working in balance and falls-prevention services should regularly screen for frailty, and patients referred to frailty services should likewise receive tailored treatment to help prevent the development of activity restriction due to concerns about falling.TJ Ellmers is supported by a Wellcome Trust Sir Henry Wellcome Postdoctoral Fellowship 222747/Z/21/Z
