摘要
Background:Prior research has established a strong link between cerebral aneurysm(CA)occurrence and inflammation.Tea intake(TI)has been found to have anti-inflammatory properties through multiple mechanisms,potentially lowering CA incidence.This study aims to employ Mendelian Randomization(MR)methodology to explore the genetic causality between TI and CA.Methods:We collected Genome-wide association study(GWAS)data for CA,TI,Green tea intake(GTI),Herbal tea intake(HTI),and Rooibos tea intake(RTI).The MR analysis employed the TwoSampleMR package and utilized the inverse variance-weighted(IVW)method.Results:The findings suggest no genetic causal relationship between TI and CA(IVW:OR=1.10,95%CI:0.59–2.05,P=0.772).Similarly,there is no genetic causal association between GTI and CA(IVW:OR=1.07,95%CI:0.91–1.26,P=0.388),HTI and CA(IVW:OR=1.00,95%CI:0.89–1.13,P=0.943),or RTI and CA(IVW:OR=1.02,95%CI:0.96–1.09,P=0.472).Conclusion:There is no genetic causal relationship between TI and CA,and the different types of tea do not change this result.Further MR analysis is needed to investigate whether there is a potential genetic causal association between the quantity of TI and CA.
