Objective:Through literature research,the distribution of TCM constitution of nonalcoholic fatty liver (NAFLD) was discussed,the common constitution types of the disease were determined,and medical evidence was provided for the prevention and treatment of NAFLD by traditional Chinese medicine.Methods: The literatures on the correlation between NAFLD and TCM constitution published in domestic joals from the database establishment to April 2020 were searched with non-alcoholic fatty liver disease and TCM constitution as the search term,and screening, quality evaluation and data extraction were conducted according to the na exclusion criteria. Statistical software stata16.0 was used for meta analysis of the included literature.Results: Sixteen studies were included. The results showed that the proportions of TCM constitution types and 95％CI of NAFLD patients were phlegm-dampness0.28(0.24,0.31), moisture-heat0.16(0.13,0.20),qi-asthenia0.13(0.10,0.16),qi-stagnation0.11(0.06,0.17),qi-stagnation0.08(0.06,0.10),yi-stagnation0.08(0.06,0.10),yi--stagnation0.08(0.06,0.10), blood stasis0.07(0.04, 0.08), yang-asthenia0.06(0.04,0.08),and special report 0.02(0.01,0.02).Conclusion:The common constitution types of patients with nonalcoholic fatty liver are phlegm-dam-pness,damp-heat,q-asthenia,and mild,especially phlegm-dampness,which are most closely related to nonalcoholic fatty liver.
