The study, which involved 481,688 individuals during an average follow-up period of 12.8 years, found that individuals who were predominantly sedentary at work had a higher risk of death from all causes (16 percent) and cardiovascular disease (34 percent) than those who did not. With those who don’t sit mainly.
As modern lifestyles become increasingly sedentary, prolonged sitting is now an integral part of normal life, although, with few exceptions, the scientific literature agrees on its harmful effects.
The study, published in the JAMA Network Open Journal, suggests that reducing prolonged sitting at work and/or increasing the amount or intensity of daily physical activity may be beneficial in reducing all-cause mortality and the higher risk of cardiovascular disease associated with chronic heart disease. Professional sitting, says the author.
The cohort study included participants in the Taiwan Health Surveillance Program who were followed between 1996 and 2017.
Data on occupational sitting, leisure time physical activity (LTPA) habits, lifestyle, and metabolic parameters were collected. The data was analyzed in December 2020.
All-cause and cardiovascular disease (CVD) mortality associated with three occupational sitting volumes (mostly sitting, alternating sitting and non-sitting, and mostly not sitting) were analyzed.
The study recorded 26,257 deaths during a mean follow-up period of 12.8 (5.67) years.
After adjusting for sex, age, education, smoking, drinking, and body mass index, those who were mostly sedentary had a 16 percent higher risk of death and a 34 percent increased risk of death from CVD compared to those who were not. Most are not sitting at work.
In this study, alternating between sitting and non-sitting at work, as well as an additional 15 to 30 minutes of physical activity per day, reduced the harm of prolonged occupational sitting.
