Functional Classification Framework Associated with Fall and Frailty Vulnerability in Community-Dwelling Adults Aged 50 Years and Older

Le résumé fourni par la source

Background: Early identification of fall and frailty risk is essential for preventing disability and maintaining functional independence in older adults. Although simple functional assessments are widely used in community settings, their combined application as a classification approach in large real-world populations remains limited. Methods: This cross-sectional study included 2979 community-dwelling adults (67.6 ± 8.3 years) enrolled in a municipal physical activity program. Participants underwent standardized assessments of gait speed, handgrip strength, and balance. A composite fall/frailty risk classification was defined using established functional cut-offs. Associations between functional variables and risk classification were examined using correlation analyses and group comparisons. Results: Overall, 45% of participants were classified as high risk. Women showed a higher prevalence compared to men (47% vs. 35%). Lower gait speed (r = −0.56), reduced handgrip strength (r = −0.32), and shorter balance time (r = −0.47) were significantly associated with higher risk classification (all p < 0.001). Conclusions: Functional performance measures are strongly associated with a composite classification of fall and frailty risk. These findings support the use of simple, scalable screening tools in community and primary care settings to identify vulnerable older adults and inform early intervention strategies.
