PURPOSE: A consensus on the definition of sarcopenic obesity (SO) is lacking, and its clinical significance in post-stroke rehabilitation remains unclear. This study aimed to investigate the prevalence of SO using the new Asia-Oceania consensus criteria in post-stroke patients and compare its association with functional outcomes against existing definitions.
METHODS: This retrospective cohort study was conducted in post-stroke patients aged ≥ 40 years at a single post-acute rehabilitation ward in Japan. SO was diagnosed according to the Asia-Oceania, JWGSO, and ESPEN/EASO criteria. The primary outcome was the Functional Independence Measure (FIM) motor score at discharge. Secondary outcome is home discharge. Multivariate regression models were used to assess the association between SO and outcomes.
RESULTS: A total of 512 post-stroke patients (mean age: 74.1 years, 53.9% men) were included in the final analysis. The prevalence of SO defined by the Asia-Oceania consensus was 3.3%, lower than that of the JWGSO (7.4%) and ESPEN/EASO (10.0%) criteria, with variable agreement between definitions (Cohen's κ: 0.474-0.816). In the fully adjusted multivariate models, SO, regardless of the definition used, was not significantly associated with FIM motor score, or discharge to home.
CONCLUSIONS: The prevalence of SO in this cohort varied substantially by definition, and the new Asia-Oceania consensus definition was not an independent predictor of functional outcomes. Our findings suggest that in this clinical setting, the robust identification of sarcopenia itself may hold greater clinical importance than the composite diagnosis of sarcopenic obesity.
