Cohort study
Cardiovascular Health and Life Expectancy Among Adults in the United States
- Prospective cohort study
- nationally representative sample
- life table method
Authors' conclusion
Adhering to a high CVH, defined as the LE8 score, is related to a considerably increased life expectancy in US adults
Study context
- Population
- Nonpregnant, noninstitutionalized US adults aged 20 to 79 years in NHANES 2005–2018, mortality linked to the National Death Index1,359 deaths
- Participants
- 23,003 participants
- Exposure
- High vs moderate vs low cardiovascular health
- Outcome
- Life expectancy at age 50 years
- Follow-up
- Median 7.8 years
Main finding
Estimated life expectancy at age 50 years
Difference
8.9 years
95% CI 6.2–11.5
By group
High CVH vs Low CVH
difference 8.9 years (95% CI 6.2–11.5)
As reported in the abstract
Observational data: associations, not effects.
Further findings
Share of gained life expectancy at age 50 attributable to reduced CVD death (high cardiovascular health (CVH))
- Attributable to reduced CVD death
- 42.6%
Life expectancy by sex (subgroup)
- Similarly significant associations of CVH with life expectancy in men and women
Life expectancy by race and ethnicity (subgroup)
- Similarly significant associations in White and Black participants but not in Mexican participants
