Abstract: Objective To investigate the correlation between fatty liver and metabolic syndrome. Methods Total of 25 fatty liver patients and 25 healthy people were analysed by ultrasonic imaging. The indexes consisted  of  body  mass  index  (BMI),  fasting  blood  glucose,  total  cholesterol,  triglyceride  and  other biochemical indicators. Both of fatty liver patients and healthy people were tested by ultrasonic imaging. Data were analyzed by SPSS 13.0. Measurement data were represented by mean ± standard deviation, and tested by t test. Multiple factors analysis was completed by logistic stepwise regression analysis.  tt Results In the fatty liver group, the levels of body mass index (BMI), total cholesterol, triglyceride and fasting blood-glucose were higher than the control group (P ＜ 0.01). In the related factors of metabolic syndrome, the BMI, triglyceride, fasting blood-glucose were independent risk factors to fatty liver (P ＜ 0.05). Conclusions Fatty liver and metabolic syndrome were closely correlated.
