Interesting statistics regarding life expectancy and longevity in the United States:
- Individuals with no chronic conditions by age 67 years can expect to live another 22.6 years on average.
- Individuals aged 67 years with 5 chronic conditions can expect to live 7.7 fewer additional years, on average.
- Individuals aged 67 years with 10 or more chronic conditions can expect to live 17.6 fewer additional years, on average.
These are some of the outcomes of a retrospective cohort study done by researchers at the Johns Hopkins University Bloomberg School of Public Health using the data from 1,372,272 Medicare fee-for-service beneficiaries who were 67 and older [DuGoff 2014].
When the researchers talk about chronic conditions (also called co-morbidities), they are referring to such conditions as cancer, cardiovascular disease, diabetes, hypertension, kidney disease, liver disease, and neurodegenerative diseases, among others.
