Summary
A new data-driven approach identified three frailty profiles in older adults, revealing distinct cognitive decline patterns. Early interventions targeting mobility or respiratory issues may slow frailty and cognitive aging.
Area of Science:
- Gerontology
- Cognitive Neuroscience
- Biostatistics
Background:
- Frailty is an aging condition linked to multisystem decline and increased risk of adverse outcomes, including cognitive impairment.
- Traditional frailty measures include the frailty phenotype and frailty index.
- A data-driven approach can identify early frailty profiles in healthy older adults.
Purpose of the Study:
- To empirically determine early frailty profiles.
- To assess the differential relationship between these profiles and longitudinal cognitive decline.
- To confirm the robustness of these patterns across sexes.
Main Methods:
- Exploratory factor analysis of 50 multi-morbidity items identified 7 health domains in 649 older adults.
- Latent profile analysis (LPA) used domain-specific deficit proportions as indicators.
- Neurocognitive speed trajectories were analyzed in relation to identified frailty profiles.
Main Results:
- Three distinct frailty profiles emerged: not-clinically-frail (NCF; 84%), mobility-type frailty (MTF; 9%), and respiratory-type frailty (RTF; 7%).
- MTF showed the steepest cognitive decline, followed by RTF, then NCF.
- Frailty index scores were highest in MTF and RTF and increased over time, consistent across sexes.
Conclusions:
- A data-driven method identified distinct early frailty profiles, potentially representing early stages of chronic frailty.
- Targeting mobility or respiratory deficits in early frailty may positively impact frailty progression and cognitive decline.
