基于不同指标诊断的肥胖与中医体质的相关性分析

Correlation Analysis on Obesity Diagnosed by Different Obesity Indices with Traditional Chinese Medicine Constitutions

目的探讨不同肥胖指标诊断的肥胖与中医体质类型的相关性。方法利用横断面现场调查法收集983例健康体检者的基本情况,以体质量指数(BMI)、腰围(WC)、腰围身高比(WHtR)、腰臀比(WHR)为肥胖指标,同时判定调查对象的中医体质类型(包括平和质、气虚质、阳虚质、阴虚质、痰湿质、血瘀质、气郁质、特禀质9种),采用典型相关分析探讨不同肥胖指标诊断的肥胖与中医体质类型的相关性。结果代表肥胖指标的典型变量V1主要受WC的影响,代表中医体质类型的典型变量W1主要受痰湿质、阳虚质、血瘀质、气郁质、气虚质、湿热质与平和质的影响。从肥胖指标的角度看,WC、WHtR诊断的肥胖与痰湿质、湿热质、平和质呈正相关;从中医体质的角度看,痰湿质、湿热质和平和质与肥胖呈正相关,阳虚质、血瘀质、气郁质与肥胖呈负相关。结论 WC是较好的肥胖指标,痰湿质、湿热质是易于发生肥胖的主要偏颇体质类型。

Objective To explore the correlations of obesity diagnosed by different indices and traditional Chinese medicine（ TCM） constitutions. Methods Health examination data of 983 subjects was collected using crosssectional survey including body mass index（ BMI）,waist circumference（ WC）,waist to height ratio（ WHtR） and waist hip ratio（ WHR）. The canonical correlation analysis was applied to study the correlations between obesity diagnosed by different indices and 9 types of TCM constitutions. Results The canonical variate V1 representing obesity indices was largely influenced by WC and the canonical variate W1 representing TCM constitutions was largely influenced by phlegm-dampness type,yang deficiency type,blood stasis type,qi stagnation type,qi deficiency type,dampness-heat type and gentle type. From an obesity indices angle,obesity diagnosed by WC and WHtR had positive correlations with phlegm-dampness type,dampness-heat type and gentle type. From a TCM constitution perspective,phlegm-dampness type,dampness-heat type and gentle type had positive correlations with obesity,while yang deficiency type,blood stasis type,qi stagnation type had negative correlations with obesity. Conclusion WC is a superior indice for obesity diagnosis and phlegm-dampness type and dampness-heat type are prone to develop obesity.
