Abstract
Background: Alcohol-associated liver disease (AALD) represents significant health burdens worldwide. This study aims to provide a comprehensive overview of the AALD outcomes that were incompletely understood. Methods: The current study utilizes data from the National Health and Nutrition and Examination Survey (NHANES) from 2011-2020, using a stratified, multistage probability cluster design. AALD in the NHANES was defined using clinical laboratory data and self-reported alcohol use, among which fibrosis-4 score of >2.67. Analysis is conducted using weighted, logistic, and Cox linear regression. Results: The initial sample included 23,206 participants aged 20 and older, with recorded cardiovascular status and AST/ALT levels. Participants reporting AALD had a higher percentage of college degrees (p < 0.001) and were more likely to be daily smokers. Asians exhibited the highest rates of AALD compared to other demographics (p < 0.001). The prevalence in private insurance is significantly greater than Medicaid, but the usage trends have been increasing in Medicaid. The trends of advanced fibrosis have been increasing in blacks and Asians, while they have been decreasing among whites and Mexicans. Those with AALD also had higher mean systolic and diastolic blood pressure, as well as elevated fasting glucose levels (p < 0.001). The mortality rate among AALD participants with heart diseases was 25%, compared to 3% among those without (p < 0.001). After adjusting for potential confounding variables, no statistically significant associations were found between AALD status and HF or CAD. However, a clinically significant increase in the odds of stroke was observed within the AALD group (p < 0.001). Conclusions: Our findings indicate Asians have the highest rates of AALD. The trends of advanced fibrosis have been increasing in blacks and Asians. There is an increased prevalence of AALD with heart diseases and a significant increase in mortality with stroke.
