- Abstract: Objective To investigate the association between Helicobacter pylori infection and nonalcoholic fatty liver disease(NAFLD).Methods This study was conducted acoording to the PRISMA guideline,with a PROSPERO registration number of CRD42023408932.Databases including PubMed,the Cochrane Library,Web of Science,Embase,CBM,Wanfang Data,CNKI,and VIP were searched for related articles published up to June 2023.This study was conducted for the case-control studies,cross-sectional studies,and cohort studies that included clear detection criteria for HP and evaluation criteria for NAFLD and performed the multivariate analysis to investigate the association between HP infection and NAFLD.Odds ratio(OR)and its 95%confidence interval(CI)were selected as the effect measures,and STATA 15.0 software was used to perform the Meta-analysis.Results A total of 33 primary studies were included,with 236 514 subjects in total.The Meta-analysis showed that HP was associated with the high prevalence rate of NAFLD(OR=1.25,95%CI:1.16—1.35,P<0.05,I2=93.7%).Subgroup analysis was conducted in terms of sample size,the diagnostic method for HP,the quality of primary study,the health status of subjects,and the type of primary study,but no clear source of heterogeneity was found.The Meta-regression analysis was conducted with the covariates of sample size,the diagnostic method for HP,the quality of primary study,the health status of subjects,and the type of primary study,and the results showed that the health status of subjects and the type of primary study might be the sources of heterogeneity.Sensitivity analysis showed that the overall results were stable,and funnel plots and the Egger test showed no significant publication bias.Conclusion HP is associated with the high prevalence rate of NAFLD in the general population,and large-scale prospective cohort studies are still needed to specifically and comprehensively evaluate the association between HP and NAFLD.
