At the same time, she pointed out that the average number of hours adults spend sitting in front of various electronic devices amounts to about 10 and a half hours per day.
In parallel, the researchers monitored an increase in the total deaths among adults (from 35 to 64 years) due to stroke, from 14.7 per 100,000 adults in 2010 to 15.4 in 2016.
While previous research has identified a close relationship between the time adults spend sitting and an increased risk of cardiovascular disease, researchers in that study reviewed health and lifestyle information from 143,000 adults from Canada who participated in health surveys over a period of more than nine years.
The researchers said the risk factors associated with an increased risk of stroke are “modifiable” factors, such as prolonged sitting.
The study’s lead author, Raed Gundy, said in a statement, “It is important to understand whether long periods of sitting can lead to brain attack in young people; Because stroke can cause premature death or significantly impair quality of life.”
The researchers reviewed the amount of time people spent each day on sedentary leisure activities; Like sitting in front of the computer, reading, watching TV, etc. Participants were divided into groups according to the number of hours, with physical activity also divided into four equal categories.
During a follow-up period of more than nine years, the participants had 2,965 strokes. And nearly 90 percent of those were ischemic strokes, the most common type of stroke, which occurs when the blood vessels that supply the brain with blood are blocked.
According to the results of the study published in the academic journal “Stroke”, adults under the age of 60 who had low physical activity were 4.2 times more likely to have a stroke compared to those who reported less than four hours of daily leisure time.
The more sedentary group – those who reported eight or more hours of inactivity and reduced physical activity – had a 7 times greater risk of stroke than those who reported less than 4 hours of sitting per day and higher levels of physical activity.
Gundy points out that it is important for adults under the age of 60 to realize that a very long period of sitting with little time spent on physical activity can have negative effects on health, including an increased risk of stroke, explaining that physical activity plays an important role. It can greatly reduce or eliminate the increased risk of stroke from prolonged sitting time.
“Physicians’ recommendations and public health policies should focus on increasing physical activity and less sitting time among young people in combination with other healthy habits to reduce the risk of cardiovascular disease and stroke,” he says.
