The Changing Prevalence of Non-Alcoholic Fatty Liver Disease (NAFLD) in Turkey in the Last Decade.

Background/aims: The true prevalence of Non-Alcoholic Fatty Liver Disease (NAFLD) is unknown in Turkey due to a lack of population-based studies. The aim of this study was (i) to determine the overall and region-specific prevalence of NAFLD in Turkey; (ii) to analyze the factors associated with the prevalence; and (iii) to determine the nationwide change in the prevalence of NAFLD in the last decade.

Materials And Methods: The 10-year data (2007 to 2016) of 113,239 apparently healthy subjects visiting the check-up clinics of Acibadem Hospitals Group were retrospectively analyzed.

Determination of the upper limits of normal serum alanine aminotransferase (ALT) level in healthy Turkish population.

Background And Aim: Recent studies have reported that the widely accepted range of upper limits of normal (ULN) alanine aminotransferase (ALT) levels (ULN<40U/L) is high for the healthy population. We aimed to find the correct ULN level for men and women in a presumed healthy liver population group.

Materials And Methods: The data of 7410 healthy subjects visiting the check-up clinics were retrospectively analysed in this study.
