Abstract Objective: To evaluate the value of ultrasonographic measurement of prehepatic fat thickness in the diagnosis of metabolic syndrome. Methods: Four hundred and ninety-six cases of community endocrinology follow-up were divided into groups according to metabolic syndrome. Ultrasound was used to measure the prehepatic fat thickness and the visceral fat thickness. The correlation between prehepatic fat thickness, intra-abdominal fat thickness and waist circumference was analyzed. ROC curve was used to analyze the optimal critical value of prehepatic fat thickness for the diagnosis of metabolic syndrome. Results: There was a positive correlation between the prehepatic fat thickness, the visceral fat thickness and the waist circumference(P<0.01). The correlation coefficient between the prehepatic fat thickness and waist circumference is more than that of the visceral fat thickness and waist circumference. The optimal critical value of the prehepatic fat thickness of male in diagnosing metabolic syndrome was 1.30 cm, the sensitivity and specificity was 0.70 and 0.81, the area under the curve was 0.82(P<0.01). The optimal critical value of the prehepatic fat thickness of female in diagnosing metabolic syndrome was 1.27 cm, the sensitivity and specificity was 0.88 and 0.74, the area under the curve was 0.87(P<0.01). Conclusion: Instead of the waist circumference, ultrasound measurement of prehepatic fat thickness is one of an accurate indicator metabolic syndrome of the degree of accumulation of intra-abdominal fat.
