Diabetes as a Potential Contributor to Dynapenia in Community‐Dwelling Older Adults in Japan: Sex‐ and Age‐Specific Cross‐Sectional Findings From the Integrated Research Initiative for Living Well With Dementia Cohort Study

Dynapenia—loss of muscle strength despite preserved muscle mass—is a clinical concern linked to functional decline in older adults. Diabetes may contribute to dynapenia; however, few studies have examined whether this association varies by sex and age. Clarifying these differences may help inform targeted prevention strategies. This study investigated the association between diabetes and dynapenia in community‐dwelling older adults in Japan, focusing on sex‐ and age‐specific differences.
