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.
