New study shows link between sedentary lifestyle and nonalcoholic fatty liver disease
140.000 middle-aged Korean men and women participated in new study that links lack of physical activity and nonalcoholic fatty liver disease (NAFLD).
The study, published in the Journal of Hepatology, used the International Physical Activity Questionnaire Short Form to measure physical activity and sitting times and ultrasound to observe fatty liver.
35% of study participants turned out to have NAFLD, due to prolonged sitting and little amounts of psychical activity.
Study co-author, Dr. Yoosoo Chang, PhD, of the Department of Occupational and Environmental Medicine, Kangbuk Samsung Hospital, Sungkyunkwan University School of Medicine in South Korea, explains how engaging in more moderate psychical activities, while reducing sitting time may decrease the risk of nonalcoholic liver disease: “Our findings suggest that both increasing participation in physical activity and reducing sitting time may be independently important in reducing the risk of NAFLD, and underlines the importance of reducing time spent sitting in addition to promoting physical activity”.
A 2 minute walk every hour has been previously reported as beneficial to fight against prolonged sitting consequences.
Michael I. Trenell, PhD, professor of the Metabolism & Lifestyle Medicine at Newcastle University in the UK, also declares about sedentary habits: “The message is clear, our chairs are slowly but surely killing us. Our body is designed to move and it is not surprising that sedentary behavior, characterized by low muscle activity, has a direct impact on physiology. With a dearth of approved drug therapies for NAFLD, lifestyle changes remain the cornerstone of clinical care. The challenge for us now is to ‘stand up’ and move for NAFLD, both physically and metaphorically.”
