A study of more than 200,000 Australians adds to the growing body of evidence that people who sit the most die the soonest.
Its most striking finding was that people who sat more than 11 hours a day had a 40% higher risk of dying in the next three years than people who sat less than four hours a day. This was after adjusting for factors such as age, weight, physical activity and general health status, all of which affect the death risk. It also found a clear dose-response effect: the more people sat, the higher their risk of death.
The results are part of the Sax Institute’s 45 and Up Study, the largest ongoing study of healthy aging in the Southern Hemisphere. It compared the self-reported daily sitting time of 222,497 Australian adults 45 years or older with their likelihood of death in the next three years.
