Abstract
AIMS: Studies have suggested that low muscle mass is associated with declining renal function in healthy populations, whether the association is relevant to patients with type 2 diabetes is not well understood. This study investigates the association between sarcopenia and estimated glomerular filtration rate (eGFR) and urinary albumin-to-creatinine ratios (UACR) in the patients with type 2 diabetes. METHODS: Two recruited groups consisted of 793 persons without diabetes (males/females=550/243) and 762 persons with type 2 diabetes (males/females=501/261). RESULTS: The non-sarcopenia population demonstrated higher ASM/HT(2), GFR (P<0.001) and lower UACR (P＜0.05) than the sarcopenia population. In studied men, the association between ASM/HT(2) and eGFR was statistically significant in the group without diabetes (OR=0.580, P=0.020), a trend which persisted in women (OR=0.491, P=0.014). The association between ASM/HT(2) and UACR persisted in studied women of two groups (OR=0.269, P=0.005; OR=0.405, P=0.008, respectively). The highest quartile of ASM/HT(2) in the non-sarcopenia population exhibited a 3.753-fold risk of abnormal eGFR within the diabetes group (OR=3.753, P=0.020). The cutoff point of ASM/HT(2) to indicate abnormal renal function for population with non-sarcopenia was 6.32kg/m(2) in the group without diabetes and 6.31kg/m(2) in diabetes group. CONCLUSIONS: Sarcopenia is associated with declining renal function, which induces lower eGFR and higher UACR. In the non-sarcopenia population, ASM/HT(2) presents as renal function risk factor, which perhaps associated with higher muscle mass to induce a greater underestimation for creatinine and urinary albumin.
