Abstract: Objective To systematically evaluate the prevalence of nonalcoholic fatty liver disease(NAFLD) among Chinese adults. Methods The studies on NAFLD in Chinese adults were searched in databases of CNKI,WanFang Data,VIP,CBM,PubMed,Web of Science,the Cochrane Library,and Embase,from inception to March 31,2022. Two researchers performed literature screening and data extraction,and assessed the quality of these studies. Meta-analysis was performed by using Stata 15.0 software. Results Totally 60 studies were included,involving 354 335 cases.The overall prevalence of NAFLD in Chinese adults was 25.5%(95%CI:22.8%-28.2%). The subgroup analysis showed that the prevalence of NAFLD increased over time. The prevalence of men was higher than that of women. The prevalence of men increased significantly in 29-<39 years old group,and reached a peak at 39-<49 years old group. The prevalence of women increased significantly 49-<59 years old group,and reached a peak at 59-<69 years old group. The higher the body mass index,the higher the prevalence. The prevalence in the northern region was higher than that in the southern region. Conclusions The prevalence of NAFLD in Chinese adults is high,with differences in prevalence by gender,age, body mass index and region. The national health department should develop a precise prevention and control strategy to curb the prevalence of NAFLD in China.
