[Work conditions, quality of life, and voice disorders in teachers].

Voice disorders are common among teachers, with adverse consequences for their work and quality of life. This study focuses on factors associated with voice-related quality of life among female teachers in the municipal school system in Belo Horizonte, Southeast Brazil. A cross-sectional study with 2,133 female teachers was conducted, using the Voice-Related Quality of Life (VRQL) questionnaire, which has two domains: socio-emotional and physical. Teachers were grouped into quartiles based on the distribution of the final score in each domain. Those in the lowest quartile were then compared with all the others for a number of factors, using multiple logistic regression analysis. Less creativity at work and poor relationship with pupils were associated with worse voice-related quality of life in both domains. Mental disorders (GHQ12 > 4) were associated with worse voice-related quality of life in the socio-emotional domain, and intra-class noise with worse voice-related quality of life in the physical domain. Improvements in working conditions are key factors for achieving better voice-related quality of life among teachers.
