Physical activity rather than sedentary behaviour affects the risk of mortality

It is not the amount of time spent sitting still that matters. Instead, the extent of physical activity is essential in reducing the risk of elderly women developing cardiovascular disease, as shown in a new Örebro study published in PLOS ONE.

"We have studied women over 65, as they are among the least active groups of the population, and run a high risk of developing ," says Fawzi Kadi, Professor at Örebro University.

A is associated with health risks such as diabetes and cardiovascular disease. But the Örebro study shows that it is the daily amount of that is crucial to a person's health.

"The study shows how important it is to encourage more physical activity. We are not talking slow everyday pace, but at least one brisk walk or other physical activity requiring some exertion," says Andreas Nilsson, researcher at Örebro University.

120 women took part in the Örebro study. After a medical examination, their physical activity was measured using an accelerometer over the course of one week.

The results may well apply to other groups, since they are in line with a meta-analysis of previous research based on a million adult men and women, which indicated that physical activity rather than sedentary behaviour affects the risk of mortality.

"Our study points in the same direction – that the of a sedentary lifestyle decrease with the extent of physical activity," says Fawzi Kadi.

This means that if one person is jogging while another is only doing less strenuous activities, the first person runs a lower risk of developing cardiovascular disease than the second – regardless of the extent of their .

"Getting up once in awhile is naturally a good thing, but doing more exercise is better for our health," concludes Andreas Nilsson.
