Abstract
BACKGROUND: Patients with type 2 diabetes mellitus (T2DM) exhibit an elevated risk of developing metabolic dysfunction-associated steatotic liver disease (MASLD). The uric acid to high-density lipoprotein cholesterol ratio (UHR) has emerged as a novel metabolic biomarker implicated in MASLD pathogenesis. This study aimed to evaluate the association between UHR and MASLD in a T2DM population. METHODS: In this cross-sectional study, we analyzed clinical data from 1081 T2DM patients (464 without MASLD, 617 with MASLD). Physiological and biochemical parameters were collected and analyzed. UHR was calculated as [uric acid (mg/dL)/HDL-C (mg/dL)] × 100%. Univariate and multivariate logistic regression analyses were performed to examine the association between UHR and MASLD. RESULTS: T2DM patients with MASLD had significantly higher UHR levels than those without MASLD (12.12[9.06-16.83] vs 10.36[7.65-14.08], p<0.001). UHR showed a strong positive correlation with TG/HDL (r =0.673, p < 0.001), moderate correlations with TG (r = 0.516, p < 0.001) and TC/HDL (r =0.548, p < 0.001), weak but significant associations with BMI (r = 0.330), WHR (r = 0.289), HOMA-IR (r = 0.121), ALT (r = 0.123), and GGT (r = 0.267) (all p < 0.05). Multivariate logistic regression showed that elevated UHR levels were significantly associated with increased MASLD risk (adjusted OR = 1.057, 95% CI: 1.016-1.100, p = 0.006), after adjusting for age, diabetes duration, BMI, blood pressure, and biochemical confounders. CONCLUSION: Elevated UHR is independently associated with MASLD in T2DM patients, suggesting its clinical relevance in MASLD screening among this high-risk population.
