Design: It is a cross-sectional study. Subjects: We collected data from physical examination subjects at Renai Branch of Taipei City Hospital from October 2013 to September 2015. The enrolled criteria required participants be 20 years or older. All subjects those with liver disease(hepatitis C virus antibody or hepatitis B surface antigen)or cirrhosis or malignant disease or biliary disease or use of antihypertensive or antidiabetic agents were excluded. Methods: Demographic data, biochemical data, body fat, visceral fat, fatty liver were collected by chart review. Body fat and visceral fat assessed by InBody 720 (Biospace, Seoul, Korea). Fatty liver was diagnosed by abdominal ultrasound. SPSS software version 21.0 was used to perform statistical analyses. A p value less than .05 was considered as statistic significance. Results: A total of 2,759 subjects were collected this study. The result of the analysis revealed that in terms of prevalence of NAFLD males exhibited a higher incidence than females. Those factors such as waist circumference, body mass index, body fat, visceral fat and metabolic syndrome were correlation with NAFLD. Multiple logistic regression was used in further analysis, showing that increased waist circumference, body mass index, body fat, visceral fat and metabolic syndrome were significant correlated factors for the present of fatty liver. Receiver operating characteristic suggested that visceral fat cut off point was 70.5 cm²(Youden''s index=0.4352). Conclusion: Visceral fat was a strong predictor of NAFLD.
