Abstract: Objective To explore the relationship between uric acid (UA) and sarcopenia in middle-aged and aged men with type 2 diabetes (T2DM). Methods All 275 men with T2DM aged over 55 years were selected from the Department of Endocrinology of Xuanwu Hospital. The uric acid (UA), 25 hydroxyvitamin D3 (25OHD3), hemoglobin A1c (HbA1c) were measured. The appendicular skeletal muscle mass (ASM), grip strength and gait speed were assessed. In addition, appendicular skeletal muscle mass index (ASMI) was calculated. The association between uric acid and sarcopenia was assessed. Results The prevalence of sarcopenia in men aged over 55 years with T2DM was 32.73%, the level of uric acid in participants of the sarcopenia group was significantly lower than that in non-sarcopenia group [(307.5±76.57) mmol/L vs (342.02±89.02) mmol/L, P=0.002)]. Pearson correlation analysis showed that UA was significantly positively correlated with ASMI (r=0.201, P=0.006), and UA was not significantly correlated with grip strength and gait speed (P>0.05). Multivariate logistic regression analysis showed uric acid was an independent protective factor for sarcopenia in middle-aged and aged men with T2DM (OR=0.89,95%CI:0.79-0.97,P=0.043). Conclusion Uric acid plays a protective role in sarcopenia in middle-aged and aged men with T2DM.

Key words: type 2 diabetes mellitus (T2DM), uric acid, sarcopenia, muscle mass
