Rationale: Sarcopenia and dysphagia are common in institutionalized older adults and share pathophysiological mechanisms affecting skeletal and oropharyngeal muscles, contributing to malnutrition.Identifying associated factors enables timely interventions to preserve functionality and QoL

Methods: A cross-sectional study was conducted in 35 institutionalized older adults. Body composition was assessed using bioimpedance (BIA), sarcopenia was diagnosed according to EWGSOP criteria, and dysphagia was evaluated with the MECV-V test. Descriptive statistics and bivariate analyses were performed using mean comparison tests and Fisher’s exact test. Statistically significant or clinically relevant variables were included in a binary logistic regression model to explore associations with S-OD overlap

Results: Mean age was 89.5±6.3 years in the overlap group and 86.9±8.3 in the non-overlap group, with no clinical or statistical impact. No differences were found in other sociodemographic variables. Functionality, measured by the Barthel Index, was lower in the overlap group (36.6vs.57.6; p=0.050), with greater dependence for dressing (p=0.046) and bathing (p=0.037). In BIA analysis, the non-overlap group had a higher Phase Angle(PA) (3.73vs.2.99; p=0.006). An inverse association was observed between PA and overlap highlighting its potential as a screening tool.

Conclusion: S-OD coexisting in institutionalized older adults is linked to greater functional decline.PA may be considered an objective and feasible tool for early screening, especially in patients with reduced functionality
