The prevalence of metabolic-associated fatty liver disease in the Turkish population: A multicenter study

Abstract

Background and Aim: The objective of the present study was to investigate the prevalence of metabolic-associated fatty liver disease (MAFLD) in patients with dyspepsia. Materials and Methods: A total of 909 consecutive patients who presented with dyspepsia at 8 tertiary care centers in Turkey between March 2019 and December 2019 were included. Results: The median age was 47 years. Among them, 30.3% of the patients were obese, 18.8% had type 2 diabetes mellitus (T2DM), 35.1% had metabolic syndrome, 84.8% had dyslipidemia, and 23.9% had hypertension. The prevalence of MAFLD was 45.5%. Among the patients with MAFLD, the prevalence of obesity, T2DM, metabolic syndrome, dyslipidemia, and hypertension was 43.3%, 24.9%, 52.5%, 92.3%, and 31.9%, respectively. MAFLD was significantly associated with all of the metabolic comorbidi-ties (p<0.001). The median Fibrosis-4 Index score of the MAFLD patients was 0.88 (range: 0.1–9.5). Of note, 53 patients with hepatic steatosis did not meet the MAFLD criteria. Conclusion: The results of the present study indicated that there was a significantly high prevalence of MAFLD observed in daily clinical practice in Turkey. Early diagnosis and prevention efforts should be implemented to reduce disease progression, and a region-based strategy is recommended.
