【摘要】：目的:探讨超声测量肝前脂肪厚度对诊断代谢综合征的价值。方法 :对496例内分泌科随访的社区人群按代谢综合征相关各组分疾病分组,用超声测量肝前脂肪厚度、腹内脂肪厚度,分析肝前脂肪厚度、腹内脂肪厚度与腰围之间的相关性,并用受试者特征(ROC)曲线分析肝前脂肪厚度诊断代谢综合征的最佳临界值。结果:肝前脂肪厚度、腹内脂肪厚度均与腰围呈正相关(P0.01);肝前脂肪厚度与腰围的相关系数大于腹内脂肪厚度与腰围的相关系数。男性肝前脂肪厚度诊断代谢综合征的最佳临界值为1.30 cm,敏感度为0.70,特异度为0.81,ROC曲线下面积为0.82(P0.01);女性肝前脂肪厚度诊断代谢综合征的最佳临界值为1.27 cm,敏感度为0.88,特异度为0.74,ROC曲线下面积为0.87(P0.01)。结论:超声测量肝前脂肪厚度可替代腰围,作为评价腹内脂肪堆积程度的准确诊断代谢综合征的指标之一。
[Abstract]:Objective: to evaluate the value of ultrasonic measurement of prehepatic fat thickness in the diagnosis of metabolic syndrome. Methods: 496 patients with endocrine department were divided into groups according to the related diseases of metabolic syndrome. The thickness of prehepatic fat and abdominal fat were measured by ultrasound, and the thickness of prehepatic fat was analyzed. The correlation between abdominal fat thickness and waist circumference. The best critical value of prehepatic fat thickness for the diagnosis of metabolic syndrome was analyzed by using the characteristic ROC curve. Results: the correlation coefficient between prehepatic fat thickness and waist circumference was higher than that between abdominal fat thickness and waist circumference. The best critical value for the diagnosis of metabolic syndrome was 1.30 cm for male prehepatic fat thickness, the sensitivity was 0.70, and the specificity was 0.81g ROC curve for the area under 0.82mP0.010.The best critical value for the diagnosis of metabolic syndrome was 1.27 cm and the sensitivity was 0.88 cm for female prehepatic fat thickness. The area under the ROC curve was 0.87 (P 0.01). Conclusion: the measurement of prehepatic fat thickness by ultrasound can replace waist circumference and be used as an index to evaluate the degree of abdominal fat accumulation in the diagnosis of metabolic syndrome.
