Abstract
Purpose
This exploratory study compared the lower-limb muscle mass (thigh muscle mass [TMM] and lower-leg muscle mass [LLMM]) in type 2 diabetic patients with and without diabetic polyneuropathy (DPN).
Methods
A total of 130 patients with type 2 diabetes, hospitalized for glycemic control, were enrolled in this cross-sectional study. TMM and LLMM were measured using the bioelectrical impedance method. The muscle mass value was normalized by the bodyweight, and the total muscle mass was calculated by combining the muscle mass on the left and right (%TMM and %LLMM). DPN was evaluated according to the Japanese criteria. Anthropometric parameters, blood pressure, laboratory data, exercise habits, medication, related index of diabetes, and diabetic complications were analyzed.
Results
Sixty patients, comprising of 32 males (47.8%) and 28 females (44.4%) with type 2 diabetes (46.2%), had DPN. The %TTM and %LLMM were significantly lower in type 2 diabetic patients with DPN than in those without DPN. Multiple regression analysis identified DPN, age, and hemoglobin A1c (HbA1c) as the determinants of %TMM, and DPN and HbA1c were identified as the determinants of %LLMM in type 2 diabetic patients.
Discussion
The %TMM and %LLMM were significantly decreased in type 2 diabetic patients with DPN. DPN was found to be the strongest determinant of %TMM and %LLMM. Preventing and improving DPN, through active physical therapy, may increase the muscle mass of the lower limbs.
