dc.description.abstractEn las sociedades modernas aproximadamente un tercio de la fuerza laboral utiliza la voz como herramienta principal de trabajo, siendo la población docente el subgrupo más grande dentro de este conjunto. Los profesores han sido reconocidos ampliamente por tener una mayor probabilidad de desarrollar desórdenes de voz en comparación con la población en general, y con otros grupos poblacionales. Una duración de sueño insuficiente o excesivo ha sido asociada con un rendimiento inadecuado de la voz, e inclusive con el inicio y desarrollo de desórdenes de esta. De forma similar, el estrés ha sido señalado como uno de los factores más relevantes asociado con los desórdenes de voz en la población docente. A la fecha, ningún estudio ha evaluado la posible relación entre el sueño y el funcionamiento vocal en docentes universitarios. Por lo tanto, la presente investigación tuvo como propósito principal caracterizar dicha asociación, evaluando además el posible efecto intermediario del estrés, los factores sociodemográficos y las condiciones de trabajo individuales, intralaborales y extralaborales de docentes adscritos a la Universidad Nacional de Colombia, sede Bogotá. Para esto, 24 docentes fueron seguidos durante 15 días continuos en los que se obtuvieron medidas diarias de auto reporte y objetivas de la calidad de sueño, el tiempo de sueño, el nivel de estrés y el funcionamiento vocal. Se usaron modelos lineales generalizados para determinar las posibles asociaciones. Entre los resultados más relevantes se encontró que el auto reporte de niveles intermedios y elevados de la calidad de sueño estuvieron asociados con incrementos estadísticamente significativos en: la desviación estándar de la presión sonora en el habla conectada, con efecto del número de estudiantes y el estado civil; y, la desviación estándar de la frecuencia fundamental, la media de la presión sonora y la presión sonora mínima en la vocal /i/. Adicionalmente, la calidad de sueño estuvo asociada con reducciones estadísticamente significativas de la presión sonora máxima en la vocal /i/, con mediación de diferentes niveles de estrés. En consecuencia, los programas de promoción de la salud vocal en el lugar de trabajo podrían incluir información sobre estos aspectos en sus planes de intervención.
dc.description.abstractIn modern societies, around one third of the workforce uses their voice as the main work tool, with the teaching population being the largest subgroup within these workers. Teachers have been widely recognized for having a greater probability of developing voice disorders compared to the general population and other population groups. Insufficient or excessive sleep duration have been associated with inadequate voice performance, and even with the onset and development of voice disorders. Similarly, stress has been identified as one of the most relevant factors associated with voice disorders among teachers. To this date, no study has evaluated the possible relation between sleep and voice functioning among college professors. Therefore, the main purpose of this research was to characterize such association, also assessing the potential intermediary effect of stress, sociodemographic factors, and the individual working conditions inside and outside the workplaces of professors who worked at Universidad Nacional de Colombia (National University of Colombia). With this in mind, 24 professors were followed-up during 15 continuous days in which daily self-reports and objective measures of sleep quality, sleep time, stress levels and voice functioning were obtained. Generalized linear models were used to determine possible associations. One of the main results was that self-report of intermediate and elevated levels of sleep quality were associated with statistically significant increases in: the standard deviation of sound pressure level in connected speech, with effect of the number of students and the marital status; and, the standard deviation of the fundamental frequency, the mean of the sound pressure level and the minimum sound pressure level in the vowel /i/. In addition, sleep quality was associated with statistically significant reductions in the maximum vowel sound pressure level /i/, mediated by different degrees of stress. Thus, workplace voice health promotion programs may include information on these aspects in their intervention plans.
