Objective@#This study aims to assess the dose-response relationship between serum ferritin (SF) and metabolic syndrome (MetS) in the two sexes.@*Methods@#We searched for articles on PubMed, the Cochrane Library, EMBASE, and the Web of Science databases that were published from 1950 to 2020. The summary odds ratio ( @*Results@#This study included 14 studies and 74,710 samples. The results of the classical meta-analysis showed that SF was positively associated with MetS ( @*Conclusions@#Our study shows that SF is significantly and positively associated with MetS, and the risk in the male population is higher than that in the female population. This finding also supports the recommendation of using SF as an early warning marker of MetS.
