Abstract：Objective:To construct a quantitative diagnosis model for obesity based on WANG Qi's classification criteria for obesity and the traditional Chinese medicine(TCM)syndromes diagnostic standards.Methods:(1)Taking Clinical Diagnosis and Treatment Terms of Traditional Chinese Medicine:Syndromes Part and WANG Qi's understanding of obesity classification as quantitative criteria,the symptoms of the quantitative diagnosis model were screened by single-factor analysis and binary Logistic regression,and the symptoms were scored by conditional probability conversion method;(2)The ROC curve was drawn,and the best diagnostic threshold was selected based on the area under the ROC curve and sensitivity and specificity;(3)The fitting degree of the diagnosis model was evaluated,and the quan-titative criteria were retrospectively tested according to the principle of diagnostic adaptability.Results:The quantitative diagnosis model of obesity was obtained as follows:Phlegm-dampness syndrome included excessive belly fat,greasy face,sticky mouth,and slippery pulse,with scores of 15,10,15,and 11 respectively,and the quantitative diagnostic threshold was 26;Qi-deficiency syndrome included pale face,muscle laxity and fatigue,the scores were 26,9 respectively,and the quantitative diagnostic threshold was 17;Phlegm-dampness and blood stasis syndrome included excessive belly fat,skin pigmentation,sublingual complexoid cyanosis,and pulse astringency.The scores were 11,18,20,and 19 respectively,and the quantitative diagnostic threshold was 20.Conclusion:TCM quantitative diagnosis model for obesity constructed in this study can reflect the characteristics of the TCM syndromes of obesity,and it has a good discriminating effect on the TCM syndromes of obesity.
