Abstract: Objective The aim of this study was to investigate the prevalence and risk factors of non-alcoholic fatty liver diseases (NAFLD) in persons at normal physical examination. Methods A total of 14415 individuals participated annually physical examination in our hospital in 2022, and all had normal routine physical examination (PE), including anthropology, hematology, biochemical parameters and ultrasonography. The univariate and multivariate Logistic regression analysis was applied to reveal the risk factors for the occurrence of NAFLD. Results Out of the 14415 individuals participating PE, the NAFLD was found in 5016 cases(34.8%), with the prevalence of 47.0% in male, much higher than 21.8%(P<0.05) in female; the body mass index (BMI), white blood cell count and platelet count in patients with NAFLD were (25.8±3.0)kg/m2, (7.0±1.7)×109/L and (263.4±62.4)×109/L, all significantly greater than [(21.9±2.6)kg/m2, (6.3±1.6)×109/L and (253.3±55.4)×109/L, respectively, P<0.05] in individuals without NAFLD; serum ALP, GGT, total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDLC), glucose (Glu) and uric acid (UA) levels in patients with NAFLD were significantly higher than in those without NAFLD (P<0.05), while serum high density lipoprotein cholesterol (HDLC) level was much lower than in those without NAFLD (P<0.05); the univariate Logistic regression analysis showed that the age, BMI, systolic blood pressure (SBP), diastolic blood pressure (DBP), ALT, ALP, GGT, TC, TG, LDLC, Glu, UA, white blood cell count and platelet count were all the factors affecting NAFLD occurrence (P < 0.05), while the HDLC level was the protective factor (P<0.05); the multivariate Logistic regression analysis demonstrated that the age (OR=1.028), BMI(OR=1.607), DBP(OR=1.039), ALP(OR=1.029), TG(OR=2.847), Glu(OR=2.716) and UA(OR=1.005) were the independent risk factors impacting the NAFLD occurrence (P<0.05), while serum HDL-C level(OR=0.054) was still the protective factor(P<0.05). Conclusion The prevalence of NAFLD is high in population at PE, and the obesity, hyperlipidemia and hyperuricemia are all the risk factors, which should be properly managed.
