Two decades of a sedentary lifestyle is associated with a two times risk of premature death compared to being physically active, according to results from the HUNT study presented today at ESC Congress 2019 together with the World Congress of Cardiology.
Study author Dr Trine Moholdt of the Norwegian University of Science and Technology, Trondheim, Norway said: “Our findings imply that to get the maximum health benefits of physical activity in terms of protection against premature all-cause and cardiovascular death, you need to continue being physically active. You can also reduce your risk by taking up physical activity later in life, even if you have not been active before.”
The aim of this study was to assess how changes in physical activity over 22 years were related to subsequent death from all causes and from cardiovascular disease. Most studies investigating the relationship between physical activity and longevity have asked participants about their level of physical activity only once, and then followed them for several years. But physical activity is a behaviour that changes in many people, so it is important to investigate how such changes over time relate to the risk of death in the future.
The HUNT study invited all residents of Norway aged 20 and older to participate in 1984-1986, 1995-1997, and 2006-2008. At all three time points, individuals were asked about their frequency and duration of leisure time physical activity. The current study used the data from the first and third surveys.
A total of 23,146 men and women were included in the analysis. Physical activity was categorised as inactive, moderate (less than two hours a week), and high (two or more hours per week). Participants were divided into groups according to their activity levels at each survey.
