title: Association of Different Physical Activity Domains on All-Cause Mortality in Adults Participating in Primary Care in the Brazilian National Health System: 4-Year Follow-up.
abstract: Evidence has shown that physical activity (PA) is associated with low mortality risk. However, data about reduced mortality due to PA are scarce in developing countries and the dose-response relationship between PA from different domains and all-cause mortality remains unclear. Thus, the aim of this study is to investigate the association of PA from different domains on all-cause mortality among Brazilian adults.
  
  
  
  679 males and females composed the study sample. Participants were divided into quartile groups according to PA from different domains (occupational, sports, and leisure-time). Medical records were used to identify the cause of the death. Cox regression analysis was performed to determine the independent associations of PA from different domains and all-cause mortality.
  
  
  
  During the follow-up period, 59 participants died. The most prevalent cause of death was circulatory system diseases (n = 20; 33.9% [21.8%-45.9%]). Higher scores of occupational (HR= 0.45 [95% CI: 0.20-0.97]), sports (HR= 0.44 [95% CI: 0.20-0.95]) and overall PA (HR= 0.40 [95% CI: 0.17-0.90]) were associated with lower mortality, even after adjustment for confounders.
  
  
  
  The findings in this study showed the importance of being active in different domains to reduce mortality risk.
