INTRODUCTION AND OBJECTIVES: Recent reclassifications of metabolic dysfunction-associated steatotic liver disease (MASLD) and metabolic-associated alcoholic liver disease (Met-ALD) have prompted the need for better characterization of these conditions. This study aimed to explore the demographic and clinical features of these liver diseases.
MATERIALS AND METHODS: Data from the 2017-2020 National Health and Nutrition Examination Survey identified 3755 participants with steatotic liver disease (SLD) using ultrasound transient elastography. The participants were categorized into MASLD, Met-ALD, alcoholic liver disease, and cryptogenic SLD.
RESULTS: MASLD patients were older and more likely to be female, with higher T2DM prevalence (19.38 % vs 9.39 % in Met-ALD, P = 0.028). Compared to MASLD, Met-ALD group showed higher liver enzymes (alanine aminotransferase, aspartate aminotransferase, gamma-glutamyltransaminase; all P < 0.001). In MASLD, steatosis (OR: 1.95, 95 %CI: 1.62-2.35, P < 0.0001) and fibrosis (OR: 1.60, 95 % CI: 1.36-1.88, P < 0.0001) were associated with increased T2DM risk, whereas moderate alcohol consumption reduced this risk (OR: 0.94, 95 % CI: 0.91-0.97, P = 0.001). T2DM was a strong predictor of advanced fibrosis (≥ F3) in MASLD (OR: 2.27, 95 % CI: 1.76-2.93, P < 0.0001). In Met-ALD, hypertension (OR: 8.81, 95 % CI: 1.50-133.50, P = 0.040) and T2DM (OR: 13.35, 95 % CI: 2.66-85.72, P = 0.002) were risk factors for advanced fibrosis.
CONCLUSIONS: While MASLD is characterized by metabolic dysfunction, Met-ALD demonstrates more pronounced hepatocellular injury. Liver elastography is essential for both fibrosis assessment and cardiometabolic risk stratification. The potential protective effect of moderate alcohol consumption on T2DM in MASLD deserves further investigation.
