Office workers are more prone to strokes and heart attacks, according to a newly published study. The new findings are not particularly surprising to the scientific community, which has warned for decades about the dangers of a sedentary lifestyle, particularly to specific organs such as the heart.
The new Chinese study, whose findings were published in JAMA Cardiology, analyzed data from more than 100,000 adults and found that people who sat for eight or more hours a day were 20 percent more likely to experience a heart attack or stroke.
These findings again sound the alarm, especially for office workers, who work for 8 hours sitting. People with this daily habit are also 49% more likely to develop heart failure, compared to those who sit for 4 hours.
According to them, reducing the amount of time spent sitting and increasing physical activity may benefit these people as much as it would benefit someone to cut down on smoking. The Chinese Academy of Medical Sciences and Peking Union Medical College followed 105,677 adults for more than a decade.
Participants came from 21 countries, had an average age of 50, and were asked how many hours per day they spent sitting on a weekly basis. Participants were divided into different groups based on how much time they claimed to spend sitting. The researchers then tracked their health records for the next few years.
By the end, there had been more than 6,200 deaths, 2,300 heart attacks, 3,000 strokes and 700 cases of heart failure among participants – though not all were fatal. According to the researchers, physical exercise contributed to reducing the risks caused by a sedentary lifestyle.
Specifically, participants who exercised the most – about 12.5 hours per week – had only a 17% increased risk of death. Conversely, those who did not exercise enough – about 2.5 hours a week – had a 50% higher risk of death due to a sedentary lifestyle.
