Predictive value of traditional Chinese medicine constitution identification and risk factors for senile nonalcoholic fatty liver disease
Objective To investigate the predictive value of traditional Chinese medicine(TCM)constitution identification and risk factors for senile nonalcoholic fatty liver disease(NAFLD).Methods This was a cross-sectional survey involving 835 participants aged 60 to 91 years old.The data of all the participants,including age,gender,past history,height,weight,waist circumference(WC),blood pressure,biochemical indicators,B-ultrasound examination were collected.An analysis of TCM constitution identification was conducted,and the participants were divided into control group and NAFLD group according to the results of B-ultrasound,and the relevant data was analyzed.Results The participants with phlegm dampness(19.46%[72/370]vs 8.39%[39/465],P<0.001)and damp-heat constitution(5.41%[20/370]vs 2.37%[11/465],P<0.05)in the NAFLD group were significantly higher than those in the control group.Phlegm-dampness constitution,damp-heat constitution,WC,fasting blood glucose(FPG),hemoglobin(Hb),uric acid(UA),gamma-glutamyltransferase(GGT),alanine aminotransferase(ALT),triglyceride(TG),glycated hemoglobin(HbA1c),body mass index(BMI),diastolic blood pressure(DBP),systolic blood pressure(SBP)had a significant positive effect on NAFLD(P<0.05),and the regression coefficients were 0.970,0.858,0.097,0.274,0.033,0.003,0.016,0.057,0.976,0.545,0.333,0.033,0.008,respectively.The area under the receiver operating characteristic(ROC)curve(AUC)for predicting NAFLD by phlegm-dampness constitution,damp-heat constitution,yang-deficiency constitution,age,GGT,ALT,high-density lipoprotein cholesterol(HDL-C),Hb,TG,BMI,UA,HbA1c,FPG,WC,DBP and SBP were:0.556,0.515,0.456,0.397,0.647,0.667,0.356,0.629,0.693,0.749,0.577,0.664,0.636,0.730,0.612.Both WC and BMI had better predictive values for NAFLD.Conclusion The NAFLD patients present significantly higher phlegm-dampness constitution and damp-heat constitution relative to the controls.Phlegm-dampness constitution,damp-heat constitution,WC,FPG,Hb,UA,GGT,ALT,TG,HbA1c,BMI,DBP and SBP have significant positive effects on NAFLD.Both WC and BMI have better predictive values for NAFLD.
