As of now, it was very much known that sitting for long hours could cause obesity, heart disease and even diabetes, but recent study from North Korea shows that it can increase the risk of liver diseases also.
Researchers found in the study that people sitting for 10 hours or more daily have 9% greater chance of developing Nonalcoholic Fatty Liver Disease (NAFLD) than those who sit lesser than that or 5 hours on average.
Physical activity was also found to be interlinked with the development of NAFLD. Persons who are physically active are 20% less likely to grow the disease than those are less active, according to according to the study published on Sept. 15 in the Journal of Hepatology.
Dr. Seungho Ryu, professor of occupational and environmental medicine at Kangbuk Samsung Hospital in South Korea and lead author of the study, told Live Science that in today’s date sitting has been increased tremendously. People are spending more time sitting in front of computer or television. More than 139,000 men and women were examined within the age range of 39.9 years for the study. They have reported their level of physical activity and sitting time as a part of the survey. The study suggests that regular physical activity does not fully protect against the risks associated with long sitting, he said. If the results of the study are confirmed, it will be important to encourage people to both increase their physical activity and reduce their sitting time to reduce the risk of developing NAFLD, he added.
Michael Trenell, a professor of metabolism and lifestyle medicine at Newcastle University in England wrote in an editorial that accompanied the study in the journal that human body is designed to move not to sit idle which is characterized by low muscle activity and has direct impact on physiology. "What remains less certain is the effect of inactive behavior on the liver," he said.
