Occupational voice users such as teachers, singers, and broadcasters have high vocal demands increasing the risk for developing voice disorders. Among occupational voice users, the literature has ...report gender differences in vocal doses as part of vocal demands. However, these differences have not been quantified.
To determine differences per gender on vocal doses among different groups of occupational voice users.
A systematic review of literature and meta-analysis were conducted on publications about vocal dose among occupational voice users. In total, 242 potential articles were found. After screening of titles and abstracts, 16 papers were included for full revision in the systematic review of literature. For the meta-analysis, 7 out of 16 papers were included.
Females had higher phonation time percentage compared with males (mean difference = 1.44, p value = .16). Nevertheless, this difference was not statistically significant. Among call centre operators, there was no difference in time doses associated with gender. Sport teachers had high values in time dose percentage, dissipation, and radiated energies.
The meta-analysis shows variations in time doses, which could be associated with the vocal demand responses for females compared with males in occupational voice settings. Future investigations are required for establishing safe limits criteria for vocal doses, as well as vocal functioning in different working context.
Objetivo. Identificar factores asociados al presentismo laboral y la calidad de vida relacionada con la voz en docentes universitarios colombianos con clases virtuales en tiempos de COVID-19.
...Metodología. Estudio transversal en el que veintinueve docentes de una universidad pública de Colombia participaron. Se utilizó un cuestionario en línea en la plataforma Google Forms, en el que se incluyeron preguntas sobre sintomatología vocal, calidad de vida asociada a la voz y al presentismo laboral asociado con sintomatología vocal. El análisis estadístico se realizó utilizando el software SPSS 25 (IBM Corporation).
Resultados. El análisis multivariado de los factores asociados con el presentismo mostró que cuatro variables aumentaban los días de presentimos laboral, siendo el reporte de síntomas de voz en el mes previo a la recolección de datos la variable que aumentó en mayor proporción, seguido de estado civil soltero, número de estudiantes y el factor 2 del IFV. Respecto a los factores asociados de la calidad de vida relacionada con la voz, el análisis multivariado mostró que el reporte de incomodidad física asociada con la fonación (Factor 2 del IFV) fue la única variable que permaneció estadísticamente significativa.
Conclusión. La fatiga vocal y la incomodidad física asociada con la fonación, así como el estado civil, están asociados con el presentismo vocal y la calidad de vida relacionada con la voz. Estos resultados resaltan las implicaciones de la sintomatología vocal en la salud, el bienestar y la economía de los docentes y las instituciones educativas, información que es importante cuando se requiere priorizar medidas preventivas y estrategias de intervención para los síntomas de voz y la fatiga vocal en docentes.
Objective. To estimate the productivity reduction costs associated to self-reported voice symptoms, low sleep quality, and high stress levels among college professors during homeworking in times of ...COVID-19 pandemic.
Methods. This cross-sectional study included fifty-eight college professors who reported their reduction in productivity at work due to self-perceived stress levels, sleep quality, and voice symptoms.
Results. High stress levels were reported by 24% of the participants, whereas 19% reported voice symptoms, and 3% low sleep quality. Costs associated with the three conditions were calculated for twenty-nine subjects. Productivity costs associated with high stress levels were higher (COP$32.345.925) than those for voice symptoms (COP$1.872.703) and low sleep quality (COP$319.733).
Conclusion: Productivity reduction costs were higher for professors who reported high levels of stress followed by participants with self-reported voice symptoms and low sleep quality, which highlight the importance of prioritizing activities to reduce stress levels and voice symptoms in workplace health promotion programs implemented in educational settings.
ABSTRACT Purpose To determine the effect of an online Workplace Vocal Health and Low Stress Levels (WVHLS) Promotion Program implemented in a Colombian university during COVID-19 pandemic. Methods ...This research was a quasi-experimental study. Twenty-nine professors participated in this study within two groups: (1) intervention group (n=17) or (2) non-intervention group (n=12). Participants in the intervention group took part in four virtual sessions about how to improve vocal health and strategies to reduce stress levels during their homeworking and online classes. Teachers filled in a questionnaire including questions about working conditions, work-related stress, and the voice functioning (including the Vocal Fatigue Index-VFI). They also recorded a voice sample of a sustained vowel on two separate occasions (before and after the follow-up). Results At the end of the follow-up, there was a tendency to reduce Factor 1 of VFI in the intervention group. Although, all participants had a longer MPT at the end of the study compared with the baseline measures, males in the intervention group had longer MPT compared with other participants. Conclusion Our results suggest a positive effect of a WVHLS promotion program on reducing vocal fatigue perception measured by means of the Vocal Fatigue Index and improving coordination and control of breathing speech measured MPT. These changes at the end of the follow-up may indicate that holistic programs that include voice care recommendations, breathing exercises, vocal warm-up, cold-down and laryngeal relaxation vocal exercises, and stress management may be beneficial for reducing work-related stress and voice symptoms among professors.
RESUMO Objetivo Determinar o efeito de um programa online de saúde vocal no local de trabalho e de redução dos níveis de estresse (SVLTRNE, ou por sua sigla em inglês, WVHLS - Workplace Vocal Health and Low Stress Levels), implementado em uma universidade colombiana durante a pandemia da COVID-19. Método O desenho do estudo foi quase experimental, com a participação de vinte e nove professores, separados em dois grupos: grupo intervenção (n=17) e grupo controle (n=12). Os participantes do grupo de intervenção participaram de quatro sessões virtuais que abordaram como melhorar a saúde vocal e as estratégias para reduzir os níveis de estresse durante o trabalho. Os professores preencheram um questionário que incluía questões sobre condições de trabalho, estresse relacionado ao trabalho e índice de fadiga vocal (IFV). Também foi gravada uma amostra de voz com uma vogal sustentada, em duas ocasiões diferentes (antes e depois da intervenção). Resultados No final desse estudo, foi observada uma tendência à redução do Fator 1 do IFV no grupo intervenção. Embora todos os participantes tivessem um TMF mais longo no final do estudo em comparação com as medidas basais, os homens do grupo de intervenção tiveram TMF mais longo em comparação com outros participantes. Conclusão Os resultados deste estudo sugerem um efeito positivo do programa de promoção WVHLS na redução da percepção de fadiga vocal e na melhora da coordenação e controle da coordenação pneumofônica, medidos com o IFV e TMF. Essas mudanças, observadas ao final do estudo, podem indicar que programas holísticos que incluem recomendações de cuidados com a voz, exercícios respiratórios, exercícios vocais de aquecimento e resfriamento, exercícios vocais de relaxamento laríngeo e controle do estresse podem ser benéficos para reduzir o estresse relacionado ao trabalho e sintomas vocais em professores.
OBJECTIVETo determine the effect of a Workplace Vocal Health Promotion Program (WVHPP) and working conditions on voice functioning of college professors.STUDY DESIGNThis is a pre-post intervention ...study.METHODSCollege professors were randomly assigned in a control group or an intervention group. Participants filled out a questionnaire and recorded a voice sample at baseline and at the end of the follow-up. This program contains four sessions (2 face-to-face and 2 virtual sessions; one per week) focused on voice hygiene, vocal training, and strategies to modify teaching-learning process.RESULTSThe Intervention group (n = 15) showed increased scores in V-RQOL in comparison with the control group (n = 14), but the effect was not statistically significant. After the program, shimmer decreased (P = 0.05), whereas MPT and HNR increased (P = 0.02 and 0.04 respectively) among professors in the intervention group after the implementation of the WVHPP. Concerning working conditions, number of students per class was statistically associated with SPL. MPT was statistically associated with age and good acoustics inside the classroom.CONCLUSIONSOur results indicate that implementation of a WVHPP, as well as working conditions, influence voice functioning measured by means of instrumental voice measures and voice-related quality of life. Therefore, workplace promotion programs may be good approaches to decrease the high prevalence of voice disorders among professors.
