Few studies have investigated the risk of mortality associated with multiple contexts of sedentary behaviour. OBJECTIVE: To examine the prospective associations of total sitting time, TV-viewing time and occupational sitting with mortality from all causes and cardiometabolic diseases. METHODS: Data from 50,817 adults aged >/=20 years from the Nord-Trondelag Health Study 3 (HUNT3) in 2006-2008 were linked to the Norwegian Cause of Death Registry up to 31 December 2010. Cox proportional hazards models examined all-cause and cardiometabolic disease-related mortality associated with total sitting time, TV-viewing and occupational sitting, adjusting for multiple potential confounders including physical activity. RESULTS: After mean follow-up of 3.3 years (137,315.8 person-years), 1068 deaths were recorded of which 388 were related to cardiometabolic diseases. HRs for all-cause mortality associated with total sitting time were 1.12 (95% CI 0.89 to 1.42), 1.18 (95% CI 0.90 to 1.57) and 1.65 (95% CI 1.24 to 2.21) for total sitting time 4- %K HUNT3 %K Adult %K Age Distribution %K Aged %K Cardiovascular Diseases/*mortality %K Cause of Death %K Female %K Humans %K Leisure Activities %K Male %K Metabolic Diseases/*mortality %K Middle Aged %K Norway/epidemiology %K Occupational Health/statistics & numerical data %K Prospective Studies %K Risk Factors %K *Sedentary Lifestyle %K Sex Distribution %K Young Adult %P 737-742
