Killer Chairs
Sedentary lifestyle provokes liver diseases
Ivan Zagorsky, Vesti Modern man moves very little and spends most of the day sitting.
Meanwhile, this lifestyle has a bad effect on health and leads to obesity, impaired posture, the development of cardiovascular diseases and diabetes. A new study by Korean scientists adds another nuisance to this list. Seungho Ryu from the Songyungwan University School of Medicine (SKKU) and his colleagues found that prolonged sitting causes non-alcoholic fatty liver disease (NAFLD). This term combines a number of liver disorders, including cirrhosis and fibrosis, which develop in people who do not abuse alcoholic beverages.
The researchers analyzed the results of a medical examination of 140 thousand Koreans, 40 thousand of whom were diagnosed with NAFLD. Scientists also compared this information with data from questionnaires assessing the level of physical activity of patients, and noticed that a sedentary lifestyle was directly associated with the development of pathology. In addition, it turned out that this relationship exists not only for overweight patients, but also for people with a body mass index (BMI) below 23, that is, normal and low.
"We found that prolonged sitting and decreased physical activity are closely associated with the development of NAFLD in a large sample of middle–aged Koreans," says co-author Yoosoo Chang in a press release 'Our chairs are killing us,' say researchers. "Our results show that both of these factors independently play an important role in increasing the risk of disease, and highlight the importance of reducing the time people spend sitting, in addition to increasing physical activity."
Experts note that the human body requires movement, and a sedentary lifestyle is characterized by low muscle activity and has a negative impact on physiology. Doctors urge instead of traveling by car to walk as much as possible, climb stairs and do exercises. Even such simple measures can have the most beneficial effect on health.
Detailed results of the new study are published in the Journal of Hepatology (Seungho Ryu et al., Relationship of sitting time and physical activity with non-alcoholic fatty liver disease).
