This study investigated physical activity as a predictor of all-cause mortality among 75- and 80-year-old people with and without chronic cardiac disease over a 10-year follow-up period.
Using the Evergreen Project data, four study groups were formed according to the respondent's self-reported level of physical activity as well as chronic cardiac diseases: active without cardiac disease (control group = ANCD), active with cardiac disease (ACD), sedentary without cardiac disease (SNCD), and sedentary with cardiac disease (SCD).
In the analyses, the ACD (HR 1.69, 95% CI 1.02-2.81) and the SNCD (1.76, 1.14-2.73) groups had almost one and a half times greater risk of dying than the control group, while the SCD group had almost three times (2.77, 1.80-4.26) greater risk of dying than the control group.
Among the older people with cardiac disease, a physically active lifestyle was associated with lower mortality.

ABSTRACT: To determine if the association between frequency of leisure-time physical activity and mortality risk differs across adulthood.
9,249 adults from the NHANES III (1988-1994) were categorized as middle-aged (40-64 years), old (65-79 years) or very old (≥80 years), and as inactive (0 bouts of physical activity/week), lightly active (1-2 bouts/week), moderately active (3-4 bouts/week) or very active (5+ bouts/week).
In all age categories, lightly, moderately, and very active adults had a lower mortality risk compared to inactive adults (p < .001). In very old adults only, being very active was associated with a lower mortality risk compared to being lightly active (HR 0.80, 95% CI 0.64-0.98; p = .03) and moderately active (HR 0.80, 95% CI 0.65-0.98; (p = .03).
The association between physical activity frequency and mortality risk is strongest in very old adults. All adults and particularly very old adults may benefit from participating in physical activity five or more times a week.

ABSTRACT: Little is known about change in physical activity (PA) and its relationship to all-cause mortality among old people. There is even less information about the association between physical activity, fitness, and all-cause mortality among people aged 80 and above. The objective is to investigate persistence and change in physical activity over 5 years as a predictor of all-cause mortality, and fitness as a mediator of this association, among people aged 80 and 85 years at the beginning of an 18-year mortality follow-up period.
