The Prevalence of Dysphonia and Dysphagia in Patients with Vitamin D Deficiency

Abstract

To investigate the prevalence of phonatory and swallowing symptoms in patients with hypovitaminosis D. All patients presenting to the endocrinology clinic and investigated for vitamin D deficiency between January 2018 and April 2018 were asked to participate in this study. Demographic data included age, gender, allergy, and history of smoking. Patients filled Voice handicap Index (VHI-10) and Eating Assessment Tool (EAT-10). A total of 136 consecutive subjects presenting to the endocrinology clinic for vitamin D testing were included: 60 with hypovitaminosis D and 76 with no hypovitaminosis D. The mean vitamin D level in the study group and controls was 13.25 ng/mL and 31.91 ng/mL, respectively. There was no significant difference in the mean score of VHI-10, nor in the mean score of EAT-10 in patients with hypovitaminosis D versus those with no hypovitaminosis D (P value >0.05). There was no significant difference in the prevalence of phonatory and dysphagia symptoms using VHI-10 and EAT-10 questionnaires between subjects with hypovitaminosis D and those with normal serum vitamin D levels.
