Background: Body fat distribution may impact nonalcoholic fatty liver disease (NAFLD) and significant fibrosis differently according to race/ethnicity. We determined the relationship between body fat distribution and NAFLD/ significant fibrosis according to race/ethnicity. Methods: A cross-sectional study of 2,395 participants used the National Health and Nutrition Examination Survey 2017 to 2018. NAFLD and significant fibrosis (≥F2) were defined by controlled attenuation parameter scores and liver stiffness measurements on transient elastography, respectively. Visceral and subcutaneous fat volumes were defined by dual-energy X-ray absorptiometry. Results: The odds ratio (OR) for NAFLD per 1-standard deviation in visceral fat volume and subcutaneous fat volume was 2.05 (95% confidence interval [CI], 1.36 to 3.09) and 1.48 (95% CI, 1.04 to 2.09) in total population, respectively. Visceral fat in non-Hispanic Blacks had the highest odds for NAFLD (OR, 2.86; 95% CI, 1.45 to 5.62), and non-Hispanic Whites (OR, 2.29; 95% CI, 1.19 to 4.40) and non-Hispanic Asians (OR, 1.61; 95% CI, 1.13 to 2.29) were in order. Significant associations between subcutaneous fat volume (OR, 2.10; 95% CI, 1.34 to 3.29; P=0.003) or visceral fat volume (OR, 1.35; 95% CI, 1.05 to 1.73; P=0.023) and significant fibrosis were noted among individuals with NAFLD. Hispanics had the highest odds for NAFLD-associated significant fibrosis (OR, 2.74; 95% CI, 1.32 to 5.70 per 1-standard deviation in subcutaneous fat volume), and non-Hispanic Whites (OR, 2.35; 95% CI, 1.11 to 4.98) and non-Hispanic Asians (OR, 2.01; 95% CI, 1.01 to 4.01) were in order. Conclusion Visceral adiposity was associated with NAFLD and significant fibrosis despite the association of subcutaneous adiposity in NAFLD and significant fibrosis. Racial/ethnic differences in the association between body fat distribution on NAFLD and significant fibrosis were noted.

Background: s/Aims: The trends in mortality of hepatocellular carcinoma (HCC) and biliary tract cancers stratified by sex and race/ethnicity in the US continue to evolve. We estimated the sex- and race/ethnicity-based trends in HCC and biliary tract cancers-related mortality in US adults with a focus on disease burden. Methods: We performed a population-based analysis using the US national mortality records from 2018 to 2023. We identified HCC and biliary tract cancer using appropriate ICD-10 codes. Temporal trends in mortality were calculated by joinpoint analysis with annual percentage change (APC). Results: Annual age-standardized mortality from HCC decreased steadily with an APC of –1.4% (95% confidence interval [CI]: –2.0% to –0.7%). While there was a linear increase in intrahepatic cholangiocarcinoma-related mortality (APC: 3.1%, 95% CI: 1.2–4.9%) and ampulla of Vater cancer-related mortality (APC: 4.1%, 95% CI: 0.5–7.9%), gallbladder cancer-related mortality decreased (APC: –1.9%, 95% CI: –3.8% to –0.0%). Decreasing trends in mortality from HCC were noted in males, not females. HCC-related mortality decreased more steeply in racial and ethnic minority individuals compared with non-Hispanic White individuals. Racial and ethnic differences in trends in mortality for biliary tract cancers depended on the malignancy’s anatomical site. Conclusions While the annual mortality for HCC and gallbladder cancer demonstrated declining trends, ICC- and AVC-related mortality continued to increase from 2018 to 2023. Although racial and ethnic minority individuals in the US experienced disproportionately higher HCC and biliary tract cancer, recent declines in HCC may be primarily due to declines among racial and ethnic minority individuals and males.

Background/Aims: Multi-society experts proposed the adoption of new terminology, metabolic dysfunctionassociated steatotic liver disease (MASLD) and steatotic liver disease (SLD). We studied the current prevalence of SLD and its subcategories in the US. Methods: Using the recent National Health and Nutrition Examination Survey from 2017 to 2023, we analyzed data from 12,199 participants (≥18 years) who completed transient elastography. SLD and its subcategories, including MASLD, metabolic and alcohol-related liver disease (MetALD), and alcohol-related liver disease (ALD), were categorized according to consensus nomenclature. Results: The age-adjusted prevalence of SLD (cut-off: 285 dB/m) was 35.0% (95% confidence interval [CI] 33.4–36.7). Within this category, the age-adjusted prevalence for MASLD was 31.9% (95% CI 30.4–33.4), MetALD 2.2% (95% CI 1.8–2.6), and ALD 0.8% (95% CI 0.6–1.1). The prevalence of SLD and MASLD showed a statistically insignificant decrease during COVID-19, while ALD increased without significance. In contrast, the prevalence of advanced fibrosis in SLD was significantly higher during the COVID-19 era, at 9.8% for 285 dB/m and 7.8% for 263 dB/m, compared to 7.4% (P=0.039) and 6% (P=0.041) in the pre-COVID-19 era. The proportion of advanced fibrosis and cirrhosis in individuals with ALD was two-fold higher than MASLD and MetALD, largely due to increases during the COVID-19 era. Conclusions While the prevalence of SLD and its subcategories remained stable, there was a significant increase in advanced fibrosis among SLD individuals during the COVID-19 era, with ALD having a proportion of advanced fibrosis and cirrhosis that was twice as high as MASLD and MetALD.
