ABSTRACT
Introduction. Contemporary occupational diseases are increasingly expressed by function disorders, which include voice disorders, forcing workers to request a leave of absence from work and leading to an incapacity to perform their work activities. Teachers have the higher prevalence of vocal disorders among the professionals who use their voices professionally, which is reported as the second cause of teaching work absences in Brazil. Objective. To analyze the environment and organization aspects of the teaching work associated with the development of voice disorder of teachers, according to the International Classification of Functioning, Disability and Health (ICF). Method. This study consisted of two steps. Initially, an integrative bibliographic review was performed to search for references related to the topic in the LILACS, MEDLINE and SCIELO databases, using the health descriptors "voice disorders" and "teachers". Then, the selected articles were read in full in order to identify the work factors associated with the voice disorder and compared with the theoretical framework of the ICF, in order to identify possible indicators of loss of functioning and capacity for teaching work resulting from voice disorders. Results. The presence of dust and noise were the most prevalent environment as-pects. In turn, the high demand for work and the lack of autonomy to perform the work were identified as factors related to the organization of the work of the teaching work, as well as stress at work and the presence of situations of violence at school as the most reported work absences.Conclusion. As shown, the factors of teaching work described impact all compo-nents of functioning and lead to the incapacity of the teacher to work. The use of the ICF may contribute to systematize and quantify, in a standardized way, the loss of functioning and work capacity resulting from voice disorders, in addition to assis-ting in the development of public health promotion policies and in the prevention of vocal disorders in teachers.
Introducción. Las enfermedades ocupacionales contemporáneas se expresan cada vez más en trastornos funcionales, que incluyen trastornos de la voz, y que obligan a los trabajadores a solicitar una excedencia del trabajo, provocando la incapacidad para realizar sus actividades laborales. Los docentes tienen la mayor prevalencia de trastornos vocales entre aquellos que usan su voz profesionalmente, lo que se reporta como la segunda causa de ausencias laborales docentes en Brasil.Objetivo. Analizar los aspectos ambientales y organizativos de la labor docente asociados al desarrollo del trastorno de la voz de los docentes, según la Clasificación Internacional de Funcionamiento, Discapacidad y Salud (CIF).Método. Este estudio consta de dos pasos. Inicialmente se realizó una revisión bi-bliográfica integradora para buscar referencias relacionadas con el tema en las bases de datos Lilacs, Medline y SciELO, utilizando los descriptores de salud "trastornos de la voz" y "docentes". Luego, se leyeron íntegramente los artículos seleccionados con el fin de identificar los factores laborales asociados al trastorno de la voz y se com-pararon con el marco teórico de la CIF, con el fin de identificar posibles indicadores de pérdida de funcionamiento y capacidad para el trabajo docente derivados de los trastornos de la voz.Resultados. La presencia de polvo y ruido fueron los aspectos ambientales más prevalentes. A su vez, la alta demanda de trabajo y la falta de autonomía para reali-zarlo fueron identificados como factores relacionados con la organización del trabajo de la labor docente, así como el estrés en el trabajo y la presencia de situaciones de violencia en la escuela como las ausencias laborales más reportadas.Conclusión. Como se muestra, los factores del trabajo docente descritos impactan todos los componentes del funcionamiento y conducen a la incapacidad del maestro para trabajar. El uso de la CIF puede contribuir a sistematizar y cuantificar, de mane-ra estandarizada, la pérdida de funcionamiento y capacidad laboral derivada de los trastornos de la voz, además de ayudar en el desarrollo de políticas de promoción de la salud pública y en la prevención de los trastornos vocales en los docentes.

Some vocal disorders in teachers are associated with occupational factors, but there are few studies that analyze the influence of vocal habits, fluid intake, mastication, and sleep on these disorders. The objective was to analyze the occurrence of vocal fatigue, hoarseness, and dry throat in elementary and high school teachers and their association with vocal habits, fluid intake, mastication, and sleep. A sample of 422 elementary and secondary school teachers was studied using a specific questionnaire. The multiple regression analysis showed that hoarseness was associated with absence of water intake (odds ratio (OR)=1.7; P=0.047), yelling/speaking loudly (OR=1.6; P=0.058), jaw-opening limitations (OR=3.8; P=0.003), average of 6 hours of sleep/night (OR=1.7; P=0.039), and waking-up feeling replenished (OR=2.0; P=0.020). The presence of vocal fatigue was significantly associated with yelling/speaking loudly (OR=2.2; P=0.013), speaking excessively (OR=2.4; P=0.023), difficulty to open the mouth to masticate (OR=6.6; P=0.003), less than 6 hours of sleep (OR=4.0; P=0.008), and waking-up feeling replenished (sometimes OR=2.8; P=0.003; or never OR=3.3; P=0.002). The presence of dry throat was associated with being a former smoker (OR=3.3; P=0.011) and having jaw-opening limitations (OR=3.9; P=0.021). In recent years, speech and hearing interventions with teachers have focused on health-care promotion actions and prevention of vocal disorders, prioritizing issues related with hydration and healthy vocal use habits. However, the findings in the present study show the need to further focus on lifestyle habits related to sleep and eating habits.
