Here is a study that uses health markers to estimate life expectancy in older adults:
Individualizing Life Expectancy Estimates for Older Adults Using the Gompertz Law of Human Mortality, 2014
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4180452/
The study is intended for clinical decision-making for preventive interventions such as cancer screening.
Here is how to estimate a life expectancy using the tables in the study:
- On Table 1, sum your "Point Score". This score is based on things like age, gender, comorbidities and difficulty with functional measures.
- On Table 2, use the "Point Score" to look up "Gompertz-Predicted Median Life Expectancy"
- On Table 3, use the "Point Score" to look up "Mortality" Predicted from HRSDevelopmentCohort
The individualizing life expectancy estimates are based on a previous study:
Development and Validation of a Prognostic Index for 4-Year Mortality in Older Adults, 2006
