Abstract

Background
Dynapenia is one of several important factors determining the prognosis of patients with diabetes mellitus. The present study aimed to identify factors associated with dynapenia in older Korean adults with diabetes.
Methods
Based on information from the 2014–2019 Korea National Health and Nutrition Examination Survey, data from 1,769 patients with diabetes ≥65 years of age were analyzed. Dynapenia was defined grip strength <28 kg in males and <18 kg in females. Subjects were divided into a dynapenia group and a normal group according to sex, and logistic regression analysis was performed to analyze factors associated with dynapenia.
Results
The prevalence of dynapenia in the entire cohort was 29.8% (n=499), with 21.6% (n=183) of 860 males and 37.2% (n=316) of 909 females. The odds ratio of dynapenia increased with advancing age in both males and females. After multivariable analysis, the factors significantly associated with dynapenia were lack of regular strength exercise (adjusted odds ratio [aOR], 3.188; 95% confidence interval [CI], 1.751–5.806) and body mass index (aOR, 0.908 per 1 kg/m 2 ; 95% CI, 0.845–0.975) among male, and lack of regular aerobic exercise (aOR, 1.511; 95% CI, 1.033–2.209) among females.
Conclusion
Advancing age in Korean adult males and females with diabetes exhibited a statistically significant association with dynapenia. In addition, significant associations with dynapenia were observed in males with lower body mass index and males who did not engage in regular strength exercise. A lack of regular aerobic exercise was statistically associated with dynapenia among females.
