Abstract

Background Evidence on the role of very low or very high volumes of leisure time physical activity (PA) on the risk of all-cause and cause-specific mortality is limited. We aimed to examine the associations of different levels of leisure time PA with the risk of all-cause, cardiovascular disease (CVD) and cancer-specific mortality. Methods Data were from 12 waves of the National Health Interview Surveys (1997-2008) linked to the National Death Index records through 31 December 2011. A total of 88 140 eligible participants aged 40-85 years were included. Results Compared with inactive individuals, those performing 10-59 min/week of PA had 18% lower risk of all-cause mortality (hazard ratio (HR): 0.82, 95% confidence interval (CI): 0.72-0.95). Those who reported 1-2 times (150-299 min/week) the recommended level of leisure time PA had 31% (HR: 0.69, 95%CI: 0.63-0.75) reduced risk of all-cause mortality. Importantly, the continued benefits were observed among those performing leisure time PA 10 or more times (≥1500 min/week) the recommended minimum level (HR: 0.54, 95% CI: 0.45-0.64). For 10-59, 150-299 and ≥1500 min/week of PA, the corresponding HRs (95% CIs) for CVD-specific mortality were 0.88 (0.67-1.17), 0.63 (0.52-0.78) and 0.67 (0.45-0.99), respectively: for cancer-specific mortality were 0.86 (0.66-1.11), 0.76 (0.64-0.89) and 0.53 (0.39-0.73), respectively. In addition, there was a larger reduction in all-cause and cause-specific mortality for vigorous vs. moderate intensity PA. Conclusions We found that beneficial association between leisure time PA and mortality starts from a low dose. Doing more vigorous exercise could lead to additional health benefits.
