Background: This study aimed to determine the prevalence of nonalcoholic fatty liver disease (NAFLD) and its related risk factors among the general population of Isfahan city located in the central part of Iran. Materials and Methods: In this cross-sectional study, the prevalence of NAFLD among 483 general adult populations was determined using ultrasonography. Anthropometric and biochemical variables were compared in groups with and without NAFLD and their predictive value for occurrence of NAFLD was investigated also. Results: Prevalence of NAFLD was 39.3%. Frequency of focal fatty infiltration (FFI), Grade I, Grade II, and Grade III of NAFLD was 9.5%, 21.1%, 7.2%, 1.4%, respectively. Prevalence of different types of NAFLD and FFI, was not different between female and male participants (P = 0.238). Ordinal regression was determined that all of the studied variables have significant predictive value for NAFLD (P < 0.001, γ = 0.615). Spearman correlation indicated that there was a significant relationship between NAFLD and BMI (r = 0.37, P< 0.001), age (r = 0.15, P = 0.001), FBS (r = 0.20, P< 0.001), cholesterol (r = 0.19, P< 0.001), triglyceride (r = 0.20, P< 0.001), LDL (r = 0.16, P< 0.001), AST (r = 0.17, P< 0.001), and ALT (r = 0.31, P< 0.001). Conclusions: Considering the high prevalence of NAFLD specially its lower grades among Isfahani adult general population and their association with studied variables, it seems that interventional studies which target-related mentioned risk factors could reduce the overall occurrence of NAFLD.
