Hypothesis
How do physical and social deficits interact in health transitions and survival among older adults?
Conclusion
Frailty significantly increases the risk of mortality and interacts with social vulnerability in older adults.
Supporting Evidence
- A 1% increase in the frailty index was associated with a 7% increase in the odds of 14-year mortality.
- The social vulnerability index had a marginally significant effect on 3-year survival.
Takeaway
As people get older, being frail can make them more likely to have health problems and die, especially when combined with social issues.
