ABSTRACT 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: Existing information regarding the optimal types and amount of physical activity for secondary prevention is controversial. We examined the association between different types of physical activity (domestic, walking, sports) and mortality in participants with established cardiovascular disease (CVD). Data were collected from the Scottish Health Surveys (1995, 1998, 2003) that were linked to a patient-based database of CVD hospital admissions and deaths. There were 837 men and women with clinically confirmed CVD at baseline, of whom 175 died over an average of 5.6+/-3.1 years of follow-up. The lowest risks for all-cause mortality were seen in participants undertaking at least 20 min/week of sports activity (fully adjusted hazard ratio=0.32, 95% confidence interval=0.16-0.65) or walking (hazard ratio=0.74, 0.53-1.04). Similar associations were observed for CVD mortality. The physically active also showed lower levels of inflammatory risk markers and greater HDL cholesterol. Men and women with existing CVD who participate in moderate-to-vigorous activity for at least 20 min/week showed the lowest risks of all-cause and cardiovascular mortality. These findings support emerging data from controlled exercise training studies.

    ABSTRACT: Patients with established coronary heart disease (CHD) are encouraged to be physically active to prevent disease progression and to prolong life. The amount and intensity of exercise required for risk reduction in patients with CHD is not yet fully resolved. Population-based prospective cohort study with 18 years of follow-up. A linkage between a Norwegian population-based study (Nord-Trøndelag health study) and the Cause of Death Registry at Statistics Norway. Exercise amount and intensity were measured at baseline (1984-1986) in 2137 men and 1367 women with CHD. During 18 years of follow-up, 1741 (81.6%) men and 1100 (80.5%) women died. Compared with the reference category (no activity), one weekly exercise session was associated with a lower all-cause mortality, both in men (relative risk 0.80, 95% confidence interval 0.68-0.94) and women (relative risk 0.68, 95% confidence interval 0.55-0.83). This inverse association became stronger with increasing frequency (P< or =0.001 for men and women). Those who reported moderate or high-intensity exercise had a somewhat lower risk of death than those who exercised with low intensity. Exercise training reduced all-cause and cardiovascular mortality in men and women with CHD. This study adds significantly to the sparse literature regarding prospective data on physical activity, exercise intensity and mortality in CHD patients.

    ABSTRACT: To assess the risk of mortality associated with different health behaviours in a Mediterranean elderly population, we have analysed the mortality experience of a cohort of 1219 non-institutionalized men and women aged 65 years or over, who had participated in the 1986 Health Interview Survey of Barcelona. At baseline, self-reported information on smoking, alcohol consumption, physical activity, and hours of daily sleep was collected through face-to-face home interviews. After 5 years of follow-up, a total of 224 (18.4%) participants had died. After adjusting for age, level of education and perceived health status, current smokers at baseline had a relative risk of dying during the follow-up of 3.0 [95% confidence interval (CI) 1.78, 5.04] compared with non-smokers. Those reporting moderate alcohol consumption had a relative risk of dying of 0.38 (95% CI 0.17, 0.86) compared with abstainers. Finally, individuals who reported a sedentary life-style had a risk of dying of 1.53 (95% CI 1.08, 2.15) compared with the more active. Although limited for interpreting associations as causal relationships, our results add to the evidence that the adverse effects on survival of smoking and of being sedentary extend later into life. Because of the high prevalence of a sedentary life-style among elderly people, results suggest that promoting physical activity may have an important role in enhancing survival in this age group.
