Abstract
INTRODUCTION: Sarcopenic dysphagia, defined as dysphagia caused by sarcopenia, is a swallowing disorder of great interest to the medical community. The objective of our study was to evaluate the prevalence and factors associated with sarcopenic dysphagia in institutionalised older adults. MATERIAL AND METHODS: An observational, analytical, cross-sectional study was conducted in a nursing home between September and December 2017, with 100 participants. The presence of dysphagia was assessed using the volume-viscosity clinical examination method, and the diagnostic algorithm for sarcopenic dysphagia was followed. The participants' grip strength, gait speed, calf circumference, nutritional assessment (Mini Nutritional Assessment), Barthel Index, cognitive assessment (Mini-Mental State Examination) and Charlson Comorbidity Index were evaluated. Bivariate and multivariate logistic regression analyses were performed. RESULTS: The median age was 84 years, and 55% were women; 48% had functional dependence, 49% had positive screening for malnutrition and 64% had some degree of dysphagia. The prevalence of sarcopenic dysphagia was 45%, and the main factors related to less sarcopenic dysphagia were a good nutritional status (OR 0.85, 95% CI, 0.72-0.99) and a better functional performance status (OR 0.98, 95% CI 0.97-0.98). CONCLUSION: Sarcopenic dysphagia has a high prevalence in institutionalised older adults; and functional dependence and poor nutritional status were associated with sarcopenic dysphagia.
