What does this research mean for the field?

Intrinsic capacity decline in older adults is heterogeneous and can be categorized into distinct profiles—such as robust, discordant, intermediate, and global impairment—which differentially predict adverse outcomes like ADL disability and falls. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To identify latent profiles of intrinsic capacity across five functional domains and evaluate their associations with adverse health outcomes in community-dwelling older adults.

Overview

Cross-sectional study identifies distinct intrinsic capacity profiles linked to disability and fall risks in older adults, indicating the need for tailored healthy aging interventions.

Key Points

To identify latent profiles of intrinsic capacity across five functional domains and evaluate their associations with adverse health outcomes in community-dwelling older adults.
Assessed intrinsic capacity across five domains (locomotion, cognition, psychological capacity, vitality, and sensory function) in a cross-sectional study of community-dwelling adults aged ≥60 years in China (N=7,151 analyzed of 9,356 recruited).
Applied latent profile analysis to determine intrinsic capacity phenotypes and used multinomial logistic and regression models to assess associations with falls, ADL disability, and quality-of-life.
Latent profile analysis classified participants into four distinct groups: Robust (20.7%), Discordant capacity (8.9%), Intermediate capacity (47.4%), and Global Impairment (23.0%).
Compared with the Robust group, odds of ADL disability were highest in the Global Impairment group (OR = 26.53, 95% CI: 17.24–40.83) and elevated in the Discordant capacity group (OR = 10.26, 95% CI: 6.37–16.53).
The Discordant capacity profile was associated with reduced odds of falls in the prior 12 months compared to the Robust group (OR = 0.44, 95% CI: 0.30–0.63), an association attenuated when physical activity was omitted from the vitality domain.
