Aim: To comparatively investigate whether dynapenia and sarcopenia, as defined by the Asian Working Group for Sarcopenia (AWGS), are associated with fear of falling in elderly patients with diabetes.

Methods: The subjects were outpatients with diabetes who were at least 65 years of age when they visited our hospital. Sarcopenia was evaluated based on the AWGS definition. The cutoff values for the appendicular skeletal mass index (multi-frequency bioelectrical impedance method), grip strength, and walking speed were, respectively, 7.0 kg/m2 for men and 5.7 kg/m2 for women, 26 kg for men and 18 kg for women, and ≤0.8 m/s for both men and women. Those with grip strength of less than or equal to the cutoff value were considered to have dynapenia. Fear of falling was assessed by a self-administered questionnaire survey with the Fall Efficacy Scale (FES) Japanese version. A multiple regression analysis was conducted using the FES score as a dependent variable and dynapenia or sarcopenia and moderators as explanatory variables.

Results: A total of 202 patients (male, n=127; female, n=75) were analyzed in this study. The FES scores of the patients with and without sarcopenia did not differ to a statistically significant extent in either male or female patients. The multiple regression analysis revealed a statistically significant association between dynapenia and the FES score in men (P=0.028).

Conclusions: In elderly outpatients with diabetes, no association was found between sarcopenia and the fear of falling in either men or women. In contrast, a statistically significant association was found between dynapenia and fear of falling in men. This suggests the importance paying attention to the fear of falling when examining elderly male diabetes patients with dynapenia.
