Both socioeconomic precariousness and frailty independently predict mortality in older adults. Identifying individuals with either factor is crucial for assessing death risk in the elderly population.
Area of Science:
- Gerontology
- Public Health
- Epidemiology
Background:
- Low socioeconomic status and frailty are significant risk factors for mortality in older adults.
- The interplay between socioeconomic status, frailty, and mortality requires further investigation.
Purpose of the Study:
- To determine the independent and combined predictive value of psychosocioeconomic precariousness and frailty on mortality in the elderly.
- To differentiate the contributions of socioeconomic factors and physical frailty in predicting death.
Main Methods:
- A prospective, population-based study (Three-City (3C) Bordeaux study) involving 1586 participants aged 65 and older.
- Assessment of psychosocioeconomic precariousness using a structured instrument and frailty using Fried's phenotype.
- 14-year follow-up to record mortality events.
Main Results:
- A total of 665 deaths (42%) occurred during the follow-up period.
- Both psychosocioeconomic precariousness (HR 1.51) and frailty (HR 1.68) were independently associated with increased mortality risk.
- These associations remained significant after adjusting for age, sex, disability, and comorbidities, with no significant interaction between the two factors.
Conclusions:
- Psychosocioeconomic precariousness and frailty represent distinct yet significant contributors to mortality risk in old age.
- Both factors should be considered in tandem when identifying elderly individuals at heightened risk of death.
- Interventions targeting both socioeconomic vulnerability and physical frailty may be necessary to reduce mortality in older populations.

Prediction Intervals
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.
