Exploring the correlation between dysphagia and laryngophayngeal reflux disorder (LPRD): A study utilizing evidence- based questionnaires

Abstract

Aim: To examine the correlation between laryngopharyngeal reflux disorder (LPRD), assessed by the Reflux Symptom Index (RSI), and dysphagia, assessed by the Eating Assessment Tool-10 (EAT-10).Method: The study included 61 participants (29 males, 32 females), aged 23-74, with LPRD. Those with RSI scores above 13 completed the EAT-10. Data were analyzed using SPSS (v29.0.10) with normality tests, Mann-Whitney U, Spearman Rank Correlation, and the Likelihood Ratio test (p< 0.05).Results: A positive correlation was found between RSI and EAT-10 scores, indicating that worsening LPRD symptoms are associated with increased dysphagia. No gender differences were observed. Older adults showed significantly higher RSI scores, with no age-related change in EAT-10 scores. A moderate correlation was found between age and RSI, but not with EAT-10.Conclusion: The study confirmed a positive relationship between LPRD severity and dysphagia, particularly in older adults. Joint assessment using RSI and EAT-10 is recommended, with collaboration among SLPs, gastroenterologists, and ENT specialists for effective management.
