A systematic review in npj Aging examines preventive interventions for older adults organized by baseline risk of healthy versus unhealthy ageing trajectories. The analysis addresses a persistent gap in geriatric prevention research: whether the same intervention produces comparable benefit in robust, pre-frail, and frail individuals. Stratifying by risk profile rather than chronological age allows preventive effort to be matched to the people most likely to respond.
Key Points
- Preventive interventions assessed by baseline risk, not chronological age
- Benefit varies between robust, pre-frail, and frail older adults
- Risk stratification improves targeting of prevention in later life
Longevity Analysis
Two people of identical age can occupy entirely different positions on the trajectory toward functional decline, and averaging their outcomes obscures who actually benefits from an intervention. Accurate interpretation of early signals — grip strength, gait speed, recovery capacity, inflammatory tone — determines whether prevention is deployed while reserve still exists or after loss has become structural. The practical implication is that the sequencing of care matters as much as its content: identify the trajectory first, then select the intervention, then sustain it long enough for muscle, vascular tissue, and immune function to respond.
