Prevalence and Clinical Implications of Osteosarcopenia in Patients With Acute Stroke: A Cross-sectional Study.

Objective: The aim of the study is to investigate the prevalence and risk factors of osteosarcopenia in patients with acute stroke.

Design: Overall, 224 patients within 2 wks of having a stroke were enrolled. Demographic characteristics, National Institutes of Health Stroke Scale, modified Rankin Scale, modified Barthel Index, Functional Ambulation Category, Berg Balance Scale, and handgrip strength were recorded. Body composition was evaluated using dual-energy x-ray absorptiometry. Patients who met the diagnostic criteria for osteoporosis and sarcopenia were defined as having osteosarcopenia.

Results: The overall prevalence of osteoporosis and sarcopenia was 46.9% and 50.9%, respectively. The prevalence of osteoporosis without sarcopenia, sarcopenia without osteoporosis, and osteosarcopenia was 18.3%, 22.3%, and 28.6%, respectively. The proportion of female sex (71.9%), median age, and National Institutes of Health Stroke Scale score were significantly higher, and modified Rankin Scale, Berg Balance Scale, modified Barthel Index, Functional Ambulation Category, and grip strength were significantly lower in patients with osteosarcopenia. Older age (≥65 yrs) (odds ratio, 15.4), female sex (odds ratio, 6.23), and lower body mass index (<25 kg/m 2 ) (odds ratio, 43.13) were independently associated with the likelihood of osteosarcopenia.

Conclusions: Osteosarcopenia may occur in acute stroke survivors. Patients with osteosarcopenia have a significantly higher stroke severity and disability. A comprehensive diagnostic approach is imperative for osteosarcopenia, thereby facilitating implementation of optimal rehabilitative strategies.
