BACKGROUND AND AIMS: There are sparse data on the epidemiology of fatty liver in the elderly Asian population. We evaluated for predictors of fatty liver and high risk of advanced fibrosis in a community-based elderly population.
METHODS: A total of 1091 participants (mean age was 74.6 ± 6.3 years) were enrolled from 2017 to 2018. Subjects with age younger than 65 years, alcoholism, and history of hepatitis B and hepatitis C were excluded. Fatty liver was diagnosed with abdominal ultrasound by using ultrasonographic fatty liver indicator, a semi-quantitative measurement grading the severity (normal, mild, and moderate-to-severe). Fibrosis-4 score was used for the prediction of the high risk of advanced fibrosis. Using a multivariable logistic regression model, we identified predictors of fatty liver and high risk of advanced fibrosis.
RESULTS: In this ambulatory elderly Asian population, the prevalence of fatty liver is 41.9% and of high risk of advanced fibrosis is 12.3%. The prevalence of fatty liver decreases (44.5% to 31.8%), and the high risk of advanced fibrosis increases (3.9% to 27.0%) with aging significantly (both P < 0.05). Metabolic syndrome is a risk factor for fatty liver (odds ratio [OR], 3.19; 95% CI, 2.41-4.22) but not for high risk of advanced fibrosis (OR, 0.67; 95% CI, 0.41-1.08). Hypertriglyceridemia decreases the risk for high risk of advanced fibrosis (OR, 0.53; 95% CI, 0.33-0.87).
CONCLUSION: Fatty liver is prevalent in the ambulatory elderly Asian population, affecting over 40% of this population. Age is a risk factor for high risk of advanced fibrosis, with the disease likely progressing from a steatotic to a fibrotic picture with age.
