title: Physical activity level and risk of death: the severance cohort study.
abstract: BACKGROUND
  Physical activity decreases deaths from cardiovascular disease and other causes; however, it is unclear whether physical activity is associated with cancer incidence and death in Asian populations.
  
  
  METHODS
  Data from 59 636 Koreans aged 30 to 93 years were collected using a questionnaire and medical examination at the Severance Hospital Health Promotion Center between 1994 and 2004. Study participants were followed for a mean duration of 10.3 years.
  
  
  RESULTS
  In the exercising group, the multivariate Cox proportional hazards model showed a lower risk of cancer death (hazard ratio [HR] = 0.72, 95% CI = 0.62-0.85) in men but not in women. Those who exercised, as compared with those who did not, had lower risks of all-cause death (men: HR = 0.68, 95% CI = 0.60-0.76; women: HR = 0.65, 95% CI = 0.53-0.79) and noncancer death (men: 0.63, 0.53-0.75; women: 0.52, 0.39-0.69). Physical activity was inversely associated with risk of noncancer death among men and women.
  
  
  CONCLUSIONS
  Physical activity was associated with lower risks of cancer death and noncancer death.
