Objective To systematically evaluate the relationship between the dietary inflammatory in-dex(DII)and the onset risk of gestational diabetes mellitus(GDM).Methods The databases such as PubMed,Web of Science,Embase,Cochrane Library,CNKI and Wanfang Data were retrieved.The retrieval time was from the database establishment to September 10,2023.Two researchers separately screened the lit-eratures,extracted the data and conducted the bias risk assessment.The meta analysis was conducted by the RevMan 5.4 software.Results A total of 8 observational studies were included,involving 96 904 pregnant women.The results of meta-analysis showed that in the classified DII,compared with the DII anti-inflammato-ry tendency group,the risk of GDM onset in the DII pro-inflammatory tendency group was increased(OR=1.27,95％CI:1.07-1.50,P=0.006).In the continuous DII,for every unit increase in DII,the risk of GDM was increased by 29％(OR=1.29,95％CI:1.13-1.48,P＜0.001).In the subgroup analysis,the most of the stratified analysis results were consistent with the main analysis results.Conclusion The current evidence suggests that the high DII scores will increase the risk of GDM onset,but the aforementioned conclusion re-quires the validation through more high quality,large samples and multicenter studies.
