Key result
Among inactive older adults, Non-Hispanic Blacks (HR 0.72, 95% CI 0.58-0.90) and Mexican Americans (HR 0.59, 95% CI 0.45-0.78) had lower all-cause mortality risk than Non-Hispanic Whites.

Ethnic mortality differences among inactive older adults should not yet change practice; hypothesis-generating and requires prospective confirmation.

Does the association between physical activity levels and all-cause or cardiovascular mortality differ by race/ethnicity in older adults?
Hazard Ratio: 0.72 (95% CI 0.58–0.9)
In older adults, the mortality risk associated with physical inactivity varies by race and ethnicity, with inactive Non-Hispanic Blacks and Mexican Americans demonstrating lower all-cause mortality risk compared to inactive Non-Hispanic Whites.
Vásquez et al. (2016) conducted a cohort in Older adults (n=4,918). Non-Hispanic Black and Mexican American race/ethnicity vs. Non-Hispanic White race/ethnicity was evaluated on All-cause mortality (HR 0.72, 95% CI 0.58-0.90). Among inactive older adults, Non-Hispanic Blacks (HR 0.72, 95% CI 0.58-0.90) and Mexican Americans (HR 0.59, 95% CI 0.45-0.78) had lower all-cause mortality risk than Non-Hispanic Whites.
