[The frequency of cachexia and its associated factors in elderly diabetic patients with chronic diseases: A study using the diagnostic criteria of the Asian Working Group for Cachexia].

Objective: To evaluate the frequency of cachexia and its associated factors using the Asian Working Group for Cachexia (AWGC) criteria in elderly patients with diabetes and chronic diseases.

Methods: The subjects were diabetic outpatients of ≥65 years of age who were managed at Ise Red Cross Hospital. Patients with chronic disease (chronic heart failure, cancer, or chronic renal failure). Cachexia was evaluated based on the AWGC criteria and was defined as a body mass index (BMI) <21 kg/m² and one or more of the following: anorexia, elevated C-reactive protein, and decreased grip strength. A logistic regression analysis was used to identify cachexia-related factors, with cachexia as the dependent variable, and various variables (basic attributes, blood glucose-related parameters, diabetic complications, comorbidities, and treatment) as explanatory variables.

Results: Two hundred forty-two patients (male, n=164; female, n=78) were included in the study. Forty patients (16.5%) had cachexia. A logistic analysis revealed that age (odds ratio (OR), 1.16; P<0.001), type 1 diabetes (OR, 15.25; P=0.002), diabetic retinopathy (OR, 5.72; P=0.001), and physical frailty (OR, 7.06; P<0.001) were associated with cachexia.

Conclusion: Elderly diabetics with chronic diseases were more likely to have cachexia. According to the AWGC criteria, the frequency of cachexia was 16.5% in elderly patients with diabetes and chronic diseases. Additionally, type 1 diabetes, diabetic retinopathy, age, and physical frailty were identified as factors associated with cachexia. In elderly diabetes patients with chronic diseases, it is therefore important to raise awareness regarding cachexia when these related factors are diagnosed.
