Abstract:
Objective To investigate the impact of the triglyceride-glucose(TyG)index on the risk of inflammatory bowel disease(IBD).Methods Based on the data from UK Biobank,participants were allocated into three groups,TyG1(≤4.564),TyG2(4.564-4.808),and TyG3(≥4.808),according to tertiles of the TyG index.Kaplan-Meier curves were established to analyze the cumulative incidence of IBD.Further,Cox proportional hazard regression was employed to analyze the hazard ratio(HR)and its 95% confidential interval(95%CI)of each group.The same analysis was conducted for different subtypes(ulcerative colitis and Crohn's disease)of IBD.Sensitive analysis based on the competing risk model was performed after excluding participants who were diagnosed within one year.Results A total of 116 423 participants were included in this study,with the median follow-up time of 12.56 years.The incidence densities of IBD in the TyG1,TyG2,and TyG3 groups were 4.47,5.94,and 6.50 per 10 000 person-year,respectively.The cumulative incidence of IBD increased with the rise in TyG,and Log-rank test results showed differences in cumulative incidence between groups(P<0.001).After adjusting the confounding factors,the HR(95%CI)of IBD in the TyG2 and TyG3 groups was 1.50(1.21-1.85)and 1.71(1.36-2.16),respectively.The results of the subgroup analysis after adjusting the confounding factors revealed that the HR(95%CI)of ulcerative colitis and Crohn's disease in the TyG3 group was 1.48(1.16-1.74)and 2.27(1.51-3.42),respectively.The sensitive analysis yielded similar results after excluding participants who were diagnosed within one year.Conclusion A high TyG index indicates an increased risk of IBD and its subtypes.
