Association between dynapenia and decline in higher‐level functional capacity in older men with diabetes

AIM: The present study aimed to investigate an association between dynapenia or sarcopenia and higher-level functional capacity in older diabetes patients. METHODS: Diabetes outpatients aged ≥65 years were prospectively enrolled. Dynapenia and sarcopenia were defined by criteria of the Asian Working Group for Sarcopenia, and higher-level functional capacity was assessed using the Tokyo Metropolitan Institute of Gerontology Index of Competence (TMIG-IC). Multiple regression analysis included TMIG-IC scores as the dependent variable and dynapenia or sarcopenia as the explanatory variables. RESULTS: The present study included 204 patients. The regression coefficient of the relationship between dynapenia and covariance-adjusted TMIG-IC in men was -1.26 (95% confidence interval -2.35 to -0.17, P = 0.024), and that of sarcopenia and TMIG-CI adjusted for covariates was 0.65 (95% confidence interval -1.26 to 2.58, P = 0.500). We observed no significant correlation between TMIG-IC scores and dynapenia or sarcopenia in women. CONCLUSIONS: A statistically significant association was found between dynapenia and decline of higher-level functional capacity in older men with diabetes. Geriatr Gerontol Int 2018; 18: 1393-1397.
