The association of physical activity with all-cause, cardiovascular, and cancer mortality among older adults
Menée sur 77 541 personnes âgées de 65 ans ou plus, cette étude taïwanaise évalue l'association entre l'activité physique et la mortalité toutes causes confondues ainsi que la mortalité par cancer ou par maladie cardiovasculaire
Objective : To evaluate the association of physical activity with all-cause, cardiovascular, and cancer mortality among older adults. Methods : A study sample consisting of 77,541 community-dwelling Taipei citizens aged ≥ 65 years were selected based on data obtained from the government-sponsored Annual Geriatric Health Examination Program between 2006 and 2010. Subjects were asked how many times they had physical activity for ≥ 30 minutes during the past 6 months. Mortality was determined by matching cohort identifications with national death files. Results : Compared to subjects with no physical activity, those who had 1–2 times of physical activity per week had a decreased risk of all-cause mortality [Hazard ratio (HR): 0.77; 95% confidence interval (CI): 0.71–0.85). Subjects with 3–5 times of physical activity per week had a further decreased risk of all-cause mortality (HR: 0.64; 95% CI: 0.58–0.70). An inverse dose–response relationship was observed between physical activity and all-cause, cardiovascular, and cancer mortality. According to stratified analyses, physical activity was associated with a decreased risk of mortality in most subgroups. Conclusions : Physical activity had an inverse association with all-cause, cardiovascular, and cancer mortality amongolder adults. Furthermore, most elderly people can benefit from an active lifestyle.
