Kim G, et al. - In a large, longitudinal, population-based 7-year cohort study, researchers determined the impacts of relative skeletal muscle mass and changes in relative muscle mass over time on the development of incident nonalcoholic fatty liver disease (NAFLD) or the resolution of baseline NAFLD. The study sample consisted of 12,624 subjects without baseline NAFLD and 2,943 subjects with baseline NAFLD who had health check-up exams. They recruited 10,534 subjects without baseline NAFLD and 2,631 subjects with baseline NAFLD in the analysis of changes in relative skeletal muscle mass over a year. They found that benefits either in the development of NAFLD or the resolution of existing NAFLD may result from increases in relative skeletal muscle mass over time.
