Vocal Health and Vocal Health Knowledge Among Occupational Voice Users in the Province of Quebec.

Voice disorders are frequent among occupational voice users such as teachers. Although these disorders can have serious personal and professional consequences, they are not often recognized as occupational diseases and little attention is paid to their prevention. This study aimed to provide a portrait of the self-reported vocal health and vocal health knowledge of occupational voice users in Quebec, Canada, and to identify risk factors associated with voice disorder symptoms. We conducted an online survey targeting occupational voice users in the province of Quebec, Canada, with a focus on those involved in teaching or training. The final sample, after excluding incomplete surveys, included 808 respondents (665 women, M = 41.5 ± 10.4 years old). The survey responses were analyzed using descriptive and inferential statistics. Results indicated that 9.8% of the respondents had a history of a diagnosed voice disorder and 68.8% of the respondents experienced at least one voice symptom on a regular basis. Ordinal logistic regressions revealed that several personal and environmental factors are associated with an increased risk of developing voice disorders symptoms: being a woman, suffering from a breathing disorder, allergies, acid reflux and/or hearing impairment, having less work experience, working with elementary school children and/or with continuous or speech noise in the background. Most of the respondents (94.6%) had never received information regarding voice disorders during their academic training and less than half of them (47.7%) knew which professionals can treat voice disorders. These findings highlight the need for formal vocal health education among both occupational voice users and their employers to improve prevention and treatment for voice disorders in an at-risk population.
