Abstract

Objectives: The aim of this study was to investigate the association between the videofluoroscopic (VFS) signs of impaired efficacy (pharyngeal residue) and safety (aspiration) swallowing and the clinical/nutritional status of patients with suspect of dysphagia.

Design: A cross-sectional study was conducted with patients submitted to videofluoroscopy.

Setting and participants: Data of 76 patients were analyzed between March 2011 and December 2014.

Measurements: The clinical history and VFS exams of patients ≥ 38 years were retrospectively analyzed.

Results: 88% patients presented Oropharyngeal Dysphagia (OD), 44.7% presented laryngeal penetration and 32% presented aspiration. 78% patients presented pharyngeal residue. Aspiration was associated with Head Neck Cancer (HNC) [Prevalence Ratio (PR): 2.27, p = 0.028] and cardiovascular disease (PR 1.96, p = 0.027). Underweight [Body Mass Index < 18.5 kg/m2] was not associated with the presence of aspiration. Underweight patients with OD had a higher prevalence rate of pharyngeal residue than those normally nourished (100% vs. 78%) (PR 1.34, p = 0.011). Pharyngeal residue was associated with male sex (PR 1.32, p = 0.040), neurodegenerative disease (PR 1.57, p = 0.021), stroke (PR 1.62, p = 0.009), cerebral palsy (PR 1.76, p = 0.006) and HNC (PR 1.73, p = 0.002).

Conclusion: In the present study, neurologic diseases, HNC, male sex and underweight were associated to impaired swallowing efficacy. Underweight, independently of the other variables, was not associated with impaired swallowing safety.

Keywords: Underweight; body mass index; oropharyngeal dysphagia; swallowing disorder.
