Abstract

Aims: Sarcopenia, which shortens healthy life expectancy, has recently been attracting attention because the Japanese population is rapidly aging. In this preliminary study, we estimated the prevalence of elderly diabetic patients who were complicated with sarcopenia and searched for any related clinical factors.

Methods: Elderly (≥65 years of age) Japanese patients with type 2 diabetes mellitus were recruited by asking doctors to supply candidates for the study. The prevalence of sarcopenia was estimated based on the criteria proposed by the Asian Working Group for Sarcopenia in 2014.

Results: Two hundred eighty-eight patients (151 males) were accepted for the study. The prevalence of sarcopenia was 15.2% in males and 15.3% in females. Multiple logistic regression analysis indicated that sarcopenia was significantly correlated with serum high-sensitivity C-reactive protein in females, in addition to age and body mass index. Female patients were then classified into four groups according to the presence or absence of impaired muscle mass and/or impaired strength. Serum high-sensitivity C-reactive protein was significantly higher in the sarcopenia group (those with impaired muscle mass and impaired strength) than in the other three groups.

Conclusions: After clarifying the prevalence of sarcopenia in elderly Japanese patients with type 2 diabetes mellitus, we found that serum high-sensitivity C-reactive protein was significantly higher in female patients with sarcopenia than in female patients without sarcopenia. Elevated serum high-sensitivity C-reactive protein requires impaired muscle mass and impaired strength.
