Mediational role of metabolic syndrome between physical activity, sedentary behavior and non-alcoholic fatty liver disease: a cross-sectional study ...

Background Physical activity (PA), sedentary behavior (SB), metabolic syndrome (MetS), and non-alcoholic fatty liver disease (NAFLD) have been linked in previous studies. Nevertheless, it is unclear whether MetS has a mediating influence on the relationships among physical activity, sedentary behavior, and non-alcoholic fatty liver disease. This study aims to assess the connections between physical activity, sedentary behavior, and non-alcoholic fatty liver disease and to explore the extent to which metabolic syndrome acts as a mediator in this association. Methods A total of 3351 adults from the National Health and Nutrition Examination Survey (NHANES) from 2017 to 2018 were included in our study. Physical activity and sedentary behavior were categorized as work activity (WA), recreational activity (RA), walking/bicycling (for commuting) and sedentary behavior to investigate the association with metabolic syndrome and non-alcoholic fatty liver disease. Besides, mediation analysis was utilized to ...
