Objective,2,To analyze the comorbidity mechanism of non-alcoholic fatty liver disease （NAFLD） and hypertension and the distribution characteristics of TCM constitution types among the elderly in Shanghai communities for the purpose of providing theoretical basis for TCM constitution adjustment of the elderly.,Methods,2,According to the prevalence of NAFLD and hypertension， elderly people who underwent routine physical examination in Beicai Community Health Service Center of Pudong New Area， Shanghai were divided into four groups： normal group， hypertension group， NAFLD group， and NAFLD combined with hypertension group （co-morbid group）. The baseline data and TCM constitutions questionnaire were retrospectively analyzed. We compared general data such as gender， waist-hip ratio， body mass index （BMI）， and laboratory indexes such as triglyceride （TG）， total cholesterol （TC）， high-density lipoproteins cholesterol （HDL-C）， alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， uric acid （UA）， and investigated the distribution characteristics of TCM constitutions. Logistic regression was used to estimate risk factors of NAFLD and hypertension and correlation analysis was performed for some factors.,Results,2,①A total of 550 participants （170 cases in the co-morbid group， 179 cases in the NAFLD group， 127 cases in the hypertension group and 74 cases in the normal group） were included. ②Compared with the condition in the normal group， BMI， waist-hip ratio， systolic blood pressure， diastolic blood pressure， fasting blood glucose （FBG）， TG， ALT， AST， UA levels increased （,P,<,0.01） and HDL-C level decreased （,P,<,0.01） in the co-morbid group； the waist-hip ratio， BMI and ALT， AST， UA levels increased （,P,<,0.01） and HDL-C level decreased （,P,<,0.05） in the NAFLD group； systolic and diastolic blood pressure and ALT and AST levels increased （,P,<,0.05， ,P,<,0.01） in the hypertensive group. Compared with the condition in the hypertension group， the waist-hip ratio， BMI and FBG， TG， ALT， AST and UA levels increased （,P,<,0.05， ,P,<,0.01） and HDL-C level decreased （,P,<,0.01） in the co-morbid group； the waist-hip ratio， BMI， systolic and diastolic blood pressure and TG， ALT， UA levels increased （,P,<,0.05， ,P,<,0.01） and HDL-C level decreased （,P,<,0.01） in the NAFLD group. Compared with the condition in the NAFLD group， BMI， waist-to-hip ratio， systolic blood pressure， diastolic blood pressure and UA level increased （,P,<,0.05， ,P,<,0.01） and HDL-C level decreased （,P,<,0.05） in the co-morbid group. ③In the co-morbid group， the dominant body constitutions were phlegm-dampness constitution （11.18%）， complex constitution （11.18%） and other biased constitutions， and the difference in the overall distribution of TCM constitutions was statistically significant compared with that of the NAFLD group and hypertension group （,P,<,0.05）. ④Logistic regression analysis showed that obesity ［,OR,=9.883， 95% ,CI（,3.347-29.180）］， high TG ［,OR,=4.306， 95% ,CI（,1.762-10.522）］， low HDL-C ［,OR,=4.796， 95% ,CI（,1.034-22.242）］， and high UA ［,OR,=3.255， 95% ,CI（,1.229-8.625）］ were risk factors for the co-morbid condition of NAFLD and hypertension， with obesity as the greatest risk factor after adjusting gender， history of diabetes， hyperlipidemia， cardiovascular diseases， and osteoporosis. ⑤According to the correlation analysis， there was a linear positive correlation between BMI and TG in the co-morbid group （,r,=0.306， ,P,<,0.01）.,Conclusion,2,The comorbidity mechanism of NAFLD and hypertension may be related to elevated BMI， TG and UA levels and reduced HDL-C level， and phlegm-dampness constitution and complex constitution are dominant TCM constitution types. The identification of phlegm-dampness and complex constitutions should be the key emphasis of TCM constitution identification when physical examination is conducted in communities so that the biased constitutions can be improved or regulated as early as possible to effectively prevent and treat the comorbid condition of NAFLD and hypertension among the elderly in communities.
