People who sit for long hours with less physical activity are more prone to have fatty liver disease than those who are moving around throughout the day.
Previously sitting for long periods has been linked to obesity, diabetes and heart disease, and now there is new evidence that it may also increase the risk of non-alcoholic fatty liver disease.
A panel of researchers from University School of Medicine, South Korea recruited nearly 140,000 middle-aged Koreans to find out the relationship between sitting time, physical activity and non-alcoholic fatty liver disease. The participants underwent a health examination between March 2011 and December 2013.
Physical activity level and sitting time were assessed using a version of the International Physical Activity Questionnaire Short Form, while the presence of fatty liver was determined using ultrasound. Of the study subjects, nearly 40,000 had non-alcoholic fatty liver disease.
The study concluded that prolonged sitting time and decreased physical activity were positively associated with the prevalence of non-alcoholic fatty liver disease among the middle-aged Korean men and women.
The scientists also found that people who sat for 10 or more hours daily had a 9 percent greater risk of developing the aforementioned condition than those who spent less than five hours a day sitting.
“Our findings suggest that both increasing participation in physical activity and reducing sitting time may be independently important in decreasing the risk of non-alcoholic fatty liver disease,” said Dr. Yoosoo Chang, study co-author from Kangbuk Samsung Hospital.
Non-alcoholic fatty liver disease is a term used to describe the accumulation of fat in the liver of those who drink little or no alcohol. The fat that accumulates can cause inflammation and scarring of the vital organ. A its most severe, the disease can progress to liver failure.
In the recent years, the amount of time spent doing sedentary activity such as sitting at a computer or watching TV has increased dramatically. The investigation proves that our chairs are slowly but surely killing us. IMAGE/news. discovery.com
