Factores asociados al presentismo laboral y la calidad de vida relacionada con la voz en docentes universitarios colombianos dictando clases virtuales en tiempos de COVID-19

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 identify associated factors of work presenteeism and voice-related quality of life among Colombian college professors teaching online classes during the COVID-19 pandemic. Methods: Cross-sectional study with the participation of twenty-nine college professors from a public university in Colombia. An online survey on the Google Forms platform was used for data collection and included questions about voice symptoms, voice-related quality of life, and work presenteeism due to voice disorders. Statistical analysis was performed using SPSS 25 software (IBM Corporation). Results: Multivariate analysis showed that four variables increased the number of presenteeism days. The variable with the higher effect was voice symptoms in the month before data collection, followed by being single, the number of students, and Factor 2 of the Vocal Fatigue Index. Regarding factors associated with voice-related quality of life, multivariate analysis showed that reporting physical discomfort during phonation (Factor 2 of the Vocal Fatigue Index) was the only variable that remained statistically significant. Conclusion: Vocal fatigue and physical discomfort during phonation, as well as marital status, are associated with work presenteeism and voice-related quality of life. These results highlight the consequences of voice symptoms on health, well-being, and economy of teachers and institutions. This information is important when preventive measurements and intervention strategies for voice symptoms and vocal fatigue among teachers need to be prioritized.

Relationship between Voice Fatigue and Voice Assessment in Patients with Voice Disorders and Applicability of Voice Fatigue Index in Korean Version / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: Vocal fatigue is a symptom and a term that has been frequently used in the clinical study. Although a recently developed vocal fatigue index (VFI), a self-report questionnaire that reliably identifies vocal fatigue patients, provides detailed characteristics of the symptom, there has been no study about the association between VFI and other voice assessment parameters. This study aimed to investigate whether there is a relationship between VFI and the established voice assessment in Korean patients. SUBJECTS AND METHOD: Two hundred fifty-seven patients with voice disorders (mean age, 49.48±14.34; 145 male and 112 female) undertook the voice assessment that consisting of perceptual judgment [Grade, Roughness, Breathiness, Asthenia, Strain (GRBAS) Scale], acoustic and aerodynamic analysis, and voice handicap index (VHI) questionnaire. All patients validated using VFI. Correlation analysis between each voice assessment and VFI was conducted. RESULTS: There were statistical significances between items of voice assessment and VFI. Among the GRBAS Scale, G, B, A, S and a number of acoustic measures were associated with vocal fatigue. In particular, these features were prominent in men. As the score of VFI increased, the sound pressure level during voicing and the phonation time from aerodynamic measures were decreased while the mean pitch was increased. In addition, VFI was closely correlated with pre-existing self-report questionnaire and VHI in both gender. CONCLUSION: These findings suggest that VFI has a significant association with pre-established voice assessment. Therefore, VFI can be used as a reliable tool for identifying and validating vocal fatigue in Korean.

Voice Fatigue test in Primary School Teachers in Chengdu and the Potential Impacts on the Voice Health Care / 听力学及言语疾病杂志

Objective To investigate the prevalence of voice disorder and voice fatigue mental state in the pri-mary school teachers in a district of Chengdu.Methods A random sampling survey included 389 teachers from a dis-trict of Chengdu after they filled out the throat symptoms questionnaire,carried out voice fatigue tests,and strobo-scopic laryngoscopy.Results The most common voice of discomfort symptoms was hoarseness,followed by sore throat,dry throat and vocal fatigue.There were 189 teachers,48.5%,with voice disorders as the voice disorder group)and 200 teachers without throat and voice disorders as the control group.The failure rate was significantly higher at 80 dB than 75 dB,and for the study group,the failure rate was higher than that of the control group.The difference was statistically significant in 1,2 and 10 minutes between the two groups(P <0.05).Conclusion Voice fatigue is very common in the primary school teachers and when high volumes are required,the voice fatigue is more serious.To reduce voice fatigue and the incidence of primary school teachers'voice disease,we should strengthen the teacher's voice health care.
