Background: Hepatic fat accumulation is the hallmark of non-alcoholic fatty liver (NAFL), for which prevalence estimates range widely from 5 to 50% in the population due to differences of screening and detection strategies. Since up to 25% of patients with NAFLD might develop advanced liver fibrosis and cirrhosis, which increase the risk of liver-associated mortality, better NAFL screening is needed. Our aim was to assess the frequency of hepatic steatosis in participants without a history of chronic liver disease who were recruited from the Occupational Health Department at Saarland University Medical Center.
