Prevalence and Predictors of Significant Fibrosis Among Subjects with Transient Elastography-Defined Nonalcoholic Fatty Liver Disease

2017 Digestive Diseases & Sciences 62;8 (2150-2158)

BACKGROUND/AIMS: Transient elastography (TE) can be used to assess the degree of liver fibrosis and steatosis. We investigated the prevalence and predictors of nonalcoholic fatty liver disease (NAFLD) with or without significant liver fibrosis in the general population. METHODS: A total of 3033 subjects without alcoholic or chronic viral liver diseases who underwent a medical health check-up including TE were recruited from April 2013 to August 2014. TE-defined NAFLD was defined as a controlled attenuation parameter of >/=250 dB/m, and significant liver fibrosis was defined as a liver stiffness (LS) value of >/=8 kPa. RESULTS: Overall, 1178 (42.9%) subjects had NAFLD. Subjects with NAFLD had significantly higher alanine aminotransferase (ALT) levels and a higher prevalence of parameters related to metabolic syndrome, such as high blood pressure, a high body mass index (BMI), glucose intolerance, and dyslipidemia than did subjects without NAFLD (all P
