Metabolic Dysfunction-Associated Steatotic Liver Disease in the Korean General Population: Epidemiology, Risk Factors, and Non-Invasive Screening.

: Metabolic dysfunction-associated steatotic liver disease (MASLD) represents a contemporary classification of liver disease linked to metabolic dysfunction. It is recognized as the main form of chronic liver disease and significantly contributes to liver-related morbidity and mortality rates. The epidemiology of MASLD is affected by ethnic background, sex, age, and environmental factors. South Korea is one of the countries that has experienced rapid urbanization. Geographical differences also play a crucial role in the prevalence and progression of the disease. Consequently, it is essential to investigate the prevalence of MASLD; its associated risk factors, particularly in relation to liver fibrosis; and the effectiveness of non-invasive screening techniques within the Korean population. : This review describes the prevalence of MASLD, the risk factors related to MASLD with liver fibrosis, and the non-invasive screening approaches suitable for the Korean general population. : This review underscores the rising incidence and implications of MASLD in South Korea. Notably, among younger demographics, there is a swift increase in both the prevalence of MASLD and its associated risk factors, indicating that MASLD is poised to become a significant public health concern. Non-invasive testing methods are increasingly utilized within at-risk groups to determine the presence of advanced fibrosis. : Addressing these complex liver diseases necessitates not only ongoing monitoring of MASLD epidemiological patterns but also a unified approach to care that integrates medical interventions with lifestyle changes.
