ObjectivesMuscle is crucial for blood glucose regulation. There is a need to prevent and treat sarcopenia in diabetes mellitus (DM). This study aimed to estimate the prevalence of sarcopenia and evaluate the association of nutritional counseling with the development of sarcopenia for people with DM.MethodsIn a cross-sectional and retrospective cohort study, people with type 2 DM were recruited from the Diabetes Shared Care Program of a teaching hospital. Muscle mass, muscle strength, and physical functional performance were evaluated using the Asian Working Group for Sarcopenia criteria. The skeletal muscle mass index was determined by dividing muscle mass by the square of the height. Clinical information, including the nutrition counseling record, was retrospectively obtained from medical records for a 2-y period.ResultsThe prevalence of low skeletal muscle mass index (presarcopenia) and sarcopenia were, respectively, 20.4% and 9.6% (including 3.1% severe) among 1292 participants. Specifically, 15.3% of participants age ≥ 65 y were categorized as having sarcopenia. With more frequent nutritional counseling, there was a lesser risk of sarcopenia; the adjusted odds ratio (95% confidence interval) was 0.51 (0.27-0.94) for ≥ 3 times/2 y compared to no counseling. DM duration and age, glycemic status and medication, and body mass index and counseling frequency had no joint effects; however, these variables (except HbA1 c) were independent risk factors for low skeletal muscle mass index and sarcopenia.ConclusionsPeople with type 2 DM have a high risk of sarcopenia. Increased nutrition counseling in outpatients was associated with less sarcopenia. Education about sarcopenia-associated risk factors should be encouraged early in the onset of DM.Copyright © 2021 Elsevier Inc. All rights reserved.
