Nonlinear Association Between the Liver Fat Content and the Risk of Hyperuricemia in Prediabetic Individuals: Evidence from Cross-Sectional Health Screening Data in China by Liu A, Li X, Zhang X, Chen K, Zou Z, Sun Y, Zhou J, Li Z, Wu X, Lv X, Li H, Guo Z, Li Y

“…This association persisted even after adjusting for other variables, indicating a heightened risk of hyperuricemia among prediabetic individuals with elevated LFC [Q4 vs Q1: odds ratio (OR 2.70), 95% confidence interval (CI) 1.93– 3.79, P < 0.001; P for trend < 0.001]. Importantly, a nonlinear relationship between LFC and hyperuricemia risk was identified in the prediabetic individuals, showing a significant increase in hyperuricemia risk when LFC exceeded 8.4% (OR per standard deviation = 1.05, 95% CI: 1.02– 1.08, P < 0.001).Conclusion: In individuals with prediabetes, a higher LFC is associated with an elevated risk of hyperuricemia, especially when LFC exceeds 8.4%.Keywords: hyperuricemia, LFC, prediabetes, Chinese adults…”
