Total physical activity was associated with a lower risk of all-cause mortality (RR 0.77; 95% CI 0.61-0.98), with benefits driven primarily by activities at home and during exercise.

Does domain-specific physical activity reduce all-cause and cardiovascular mortality in an aging population?
Physical activity undertaken at home and during exercise, but not at work or for transport, is associated with reduced all-cause and cardiovascular mortality in older adults.
Effect estimate: RR 0.77 (95% CI 0.61-0.98)
PURPOSE: The purpose of this study was to describe the association of the overall and domain-specific physical activity on all-cause and cardiovascular mortality. A large body of epidemiological evidence suggests a strong and consistent inverse association between physical activity and mortality risk. However, it is unclear how this association varies according to the domain of life in which the activity takes place. METHODS: In an English population-based cohort of 14,903 participants (mean age = 63 yr), total and domain-specific physical activity was assessed using a validated questionnaire (EPAQ2). After a median follow-up of 7 yr, there were 1128 deaths, with 370 from cardiovascular disease. RESULTS: The relative risks (95% confidence interval) for all-cause mortality due to physical activity undertaken at home, during exercise, at work, for transport, and in total were 0.81 (0.66-0.99), 0.66 (0.54-0.80), 0.84 (0.55-1.30), 0.82 (0.67-1.00), and 0.77 (0.61-0.98), respectively, after adjustment for baseline age, sex, social class, alcohol consumption, smoking status, history of diabetes, history of cancer, and history of cardiovascular disease and stroke. Cardiovascular mortality was inversely associated with physical activity undertaken at home (P for trend = 0.03), during exercise (P for trend = 0.001), and in total (P for trend = 0.007). The results were unchanged after excluding individuals with a history of heart disease, stroke, and cancer at baseline and those who died within the first 2 yr of follow-up. CONCLUSIONS: In this study, physical activities at home and during exercise are associated with lower risk of mortality, whereas occupational and transportation-related activities are not. Promoting the potential benefits of physical activity undertaken at home and during exercise may be an important public health message for aging populations.
Besson et al. (Sat,) reported a cohort. Total and domain-specific physical activity was evaluated on All-cause mortality (RR 0.77, 95% CI 0.61-0.98). Total physical activity was associated with a lower risk of all-cause mortality (RR 0.77; 95% CI 0.61-0.98), with benefits driven primarily by activities at home and during exercise.
