Abstract

PURPOSE:

To provide a quantitative assessment of the occurrence of voice disorders among teachers and to identify associated work-related and individual factors in the teaching profession.

METHOD:

A systematic review was conducted using three computerized databases on the occurrence of voice disorders among teachers and their associations with work-related and individual factors. Some of the keywords used were: "teacher", "voice disorder", "voice problem", and "dysphonia". Information regarding the occurrence of voice disorders and associations between work-related and individual factors and voice disorders were extracted from each paper. Occurrence and associations were expressed in prevalence and odds ratios, respectively.

RESULTS:

In total, 23 publications met the criteria for inclusion. All publications were cross-sectional studies. Prevalence estimates varied widely, reflecting disparity in definitions of "voice problem". Teachers had a significantly increased occurrence of voice disorders compared to other occupations. Several work-related and individual factors were consistently associated with voice disorders, most notably high levels of noise in classrooms, being a physical education instructor, and habitual use of a loud speaking voice.

CONCLUSION:

This review shows that teachers report voice disorders more often than non-teachers. Various work-related and individual factors are associated with reported voice disorders. Longitudinal studies are urgently required to get more insight into the development of voice disorders, their work-related determinants, and the consequences of these voice disorders for functioning and work performance among teachers.

LEARNING OUTCOMES:

Describe the occurrence of voice disorders among teachers. Identify some work-related factors of voice disorders among teachers. Interpret the quality of the publications to describe or analyze the relationship between working conditions and voice disorders among teachers.
