We aimed to determine the association between sarcopenia and frailty in Japan's hyperaged society. investigated incidence of among 423 community-dwelling older adults (304 women 119 men ; mean age : 77.0 years). Interviews, Kihon Checklist (KCL) assessments, physical function tests, anthropometric measurements were performed at baseline. Sarcopenia was defined according Asian Working Group for 2019 criteria, with a KCL score ≥7 indicating frailty. Eight patients (1.9%) had alone, 113 (26.7%) 26 (6.1%) both The instrumental activities daily living (IADL) scores significantly higher all groups. Logistic regression analysis showed IADL. receiver operating characteristic curves total IADL analyzed cutoff value assessing 7.000, while that KCL-IADL 2.000. Approximately 6.1% diagnosed using KCL. These conditions found impair Hence, interventions addressing may help prevent decline J. Med. Invest. 72 139-147, February, 2025.
