Baseline VFSS parameters, including the penetration-aspiration scale (PAS), residue measures, and functional dysphagia scale (FDS), were compared. Nutritional status was assessed using the Mini Nutritional Assessment-Short Form (MNA-SF) at baseline and 3 months. Multivariable linear regression analyses were performed to evaluate the association between baseline VFSS parameters and change in nutritional status (\u0394MNA-SF), adjusting for age, sex, Charlson Comorbidity Index, baseline MNA-SF, and baseline functional oral intake scale (FOIS).Results: Of 54 patients, 44 were included in the final analysis. Higher PAS scores were significantly associated with a greater decline in nutritional status (B=\u20130.423, p=0.009) after adjusting for baseline MNA-SF and clinical covariates. This association remained significant after further adjustment for baseline FOIS (B=\u20130.428, p=0.012). PAS category also showed a significant association with \u0394MNA-SF. Among the evaluated predictors, PAS demonstrated the highest explanatory power across the nested models, whereas residue measures, FDS, and baseline FOIS were not significantly associated with nutritional decline.Conclusion: The severity of airway invasion on a VFSS is independently associated with subsequent nutritional decline in patients with non-neurological dysphagia beyond the effect of baseline functional oral intake. A VFSS-based assessment of swallowing safety may help to identify patients at risk of nutritional deterioration and support early nutritional interventions.<\/jats:p>","DOI":"10.12701\/jyms.2026.43.68","type":"journal-article","created":{"date-parts":[[2026,9,22]],"date-time":"2026-09-22T10:16:43Z","timestamp":1790072203000},"page":"68","update-policy":"https:\/\/doi.org\/10.12701\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Airway
