Physical Resilience and Its Influencing Factors Among Older Patients with Fragility Fractures: A Cross-Sectional Study Based on Latent Profile Analysis

Background: Physical resilience (PR) plays a critical role in the functional recovery of older adults following fragility fractures, yet individual heterogeneity remains underexplored. Objective: To identify latent profiles of PR among older adults following fragility fractures and to examine their biopsychosocial predictors. Methods: From October 2025 to March 2026, 224 older adults with fragility fractures were recruited using convenience sampling from a tertiary hospital in China. Data were collected using demographic questionnaires, the Physical Resilience Instrument for Older Adults, Perceived Social Support Scale, and General Self-Efficacy Scale. Latent profile analysis identified profiles, followed by multinomial logistic regression examining biopsychosocial predictors. Results: Three distinct resilience profiles emerged: low resilience—physically and mentally vulnerable (31.7%); moderate resilience—limited adaptation (51.5%); and high resilience—potential activated (16.8%). Significant profile predictors included handgrip strength, nutritional risk, marital status, general self-efficacy, and perceived social support (p < 0.05). Conclusions: The distinct heterogeneity of PR among older adults with fragility fractures underscores the necessity for tailored, risk-stratified nursing. In clinical practice, interventions for the highly vulnerable low-resilience group should prioritize multidisciplinary nutritional optimization and early physical rehabilitation. For patients with moderate resilience, integrating spousal support and cognitive-behavioral strategies is crucial to enhance self-efficacy and prevent functional decline. For the high-resilience cohort, leveraging robust social support networks and empowerment-based strategies can maximize their intrinsic recovery potential.
