Knowledge of Egyptian faculty members about voice care: a national cross-sectional study

Abstract
Background
The university teaching faculty members are one of the occupational fields in education that are more exposed to voice disorders. The current study aimed to examine the association among vocal symptoms reported by faculty teaching professionals, impact of voice problems on daily activities, their vocal habits, and knowledge on vocal hygiene in relation to specialist consultation and to identify which of the assessed factors triggered the most for medical consultation. An online questionnaire was completed by 420 faculty teaching professionals from 7 universities in Egypt between November 2019 and December 2019.

Results
All assessed vocal symptoms were significantly associated with specialist consultation (p-value <0.01). Most common bad vocal habits included increased voice loudness (71.2%), talking for long time (69.3%), and frequent throat clearance (54.0%). The most commonly reported preventive measures included avoid screaming (88.3%), stop smoking (87.1%), and taking periods of voice rest (86.4%). The strongest predictor of having specialist consultation was frequent throat clearance, recording an odds ratio of 23.809.

Conclusion
Based on information obtained from the current study, ideas are suggested for setting up vocal hygiene programs throughout a professional voice career for keeping a healthy voice. Avoid passive smoking and using microphones are considered remarkable adequate methods for healthy voice.
