Abstract
BackgroundExcess weight is a progressive metabolic epidemic, and inflammation plays an important role in the progression of disease. Insulin resistance (IR) is an important feature of obesity, but it does not reflect systemic inflammation. Currently, there is a lack of effective clinical tools for early risk stratification and intervention in physically active people.MethodsThis was a prospective cohort of 72,262 overweight but physically active persons in the UK Biobank. The TyG was combined with hsCRP, waist circumference (WC), or body mass index (BMI) as indices of IR. Adjusted Cox regression, interaction tests, restricted cubic splines (RCS) analysis, Kaplan-Meier analysis, and Harrell's C-index were used to examine the relations and time-dependent predictive power.ResultsDuring 12.7 years of follow-up, 1,477 participants developed metabolic dysfunction-associated fatty liver disease (MAFLD). RCS analysis suggested TyG-hsCRP had a nonlinear positive correlations with all-cause mortality. Compared to the lowest quartile group, the corrected hazard ratio (HR) (95% confidence interval [CI]) of new-onset MAFLD in maximum quartile groups for TyG-hsCRP was 1.94(1.62-2.32), for TyG-WC was 1.78(1.44-2.18), for TyG-BMI was 1.36(1.12-1.65), and for TyG was 1.41(1.15-1.72). The relation between C-index of TyG-hsCRP and MAFLD was higher than that of other TyG indices. Similar results were observed in all-cause mortality.ConclusionTyG-hsCRP is superior to other indices for identifying risk of MAFLD and all-cause mortality in overweight but physically active people. Our findings suggest the importance of inflammatory metabolism and provide evidence for effectively early anti-inflammatory treatments.</p>
