Background: Objective of the present cross-sectional study was to investigate the impact of caffeine consumption on the severity of fatty liver and serum alanine aminotransferase (ALT) concentrations in a random population sample. Methods: All subjects (n = 1223; 713 women, 510 men; average age 41.8 ± 12.7 years) underwent ultrasonographic examination of the liver and completed a standardized questionnaire regarding personal and lifestyle data, in particular relating to coffee consumption and past medical history. In addition, anthropometric data were documented and laboratory examinations performed. Statistical interpretation of the data was performed descriptively and by means of bivariate and multivariate analysis. Results: Data of the present study demonstrated a significant association between hepatic steatosis male gender (p < 0.0001), advanced age (p < 0.0001) and elevated body-mass index (BMI; p < 0.0001). No association between caffeine consumption and the severity of fatty liver was identified. For elevated serum ALT concentrations, a significant association was found for male gender (p < 0.0001) and advanced BMI (p < 0.0001). An association between caffeine consumption and elevated serum ALT concentrations was not identified. Conclusions: The findings of the present study provide no evidence for an association between caffeine consumption and either the prevalence or severity of hepatic steatosis or serum ALT concentrations.
