Implication
Secondary analysis explores associations between social vulnerability and mortality in community-dwelling elderly people, suggesting important health implications.
Key Points
- This study aims to define social vulnerability, compare it with frailty, and examine its association with mortality among elderly individuals.
- Secondary analysis of data from two cohort studies (CSHA and NPHS) involving 6355 community-dwelling elderly individuals.
- Construction of social vulnerability indices based on self-reported items measuring social deficits.
- Assessment of mortality over five to eight years, controlling for age, sex, and frailty.
- Each additional social deficit corresponds to an increased odds of mortality (CSHA: OR=1.05, 95% CI: 1.02-1.07; NPHS: OR=1.08, 95% CI: 1.03-1.14).
- Social vulnerability and frailty were moderately correlated, with women exhibiting higher vulnerability than men.
- Survival analysis revealed a significant gradient across social vulnerability quartiles.
