Teachers are more prone to develop voice problems (VPs) when compared with other professional voice users. The aim of present study was to investigate the prevalence and risk factors of VPs among primary school teachers in India.
Epidemiological cross-sectional survey.
Self-reporting questionnaire data were collected from 1082 teachers.
Out of 1082 teachers who participated in the present study, 188 teachers reported VPs that account for a prevalence rate of 17.4%. Tired voice after long hours of talking was the most frequently reported symptom, followed by sore/dry throat, strain in voice, neck muscle tension, and difficulty in projecting voice. The adjusted odds ratio values showed number of years of teaching, high background noise levels in the classroom, experiencing psychological stress while teaching classes, improper breath management (holding breath while speaking), poor focus of the tone (clenching jaw/teeth while speaking), upper respiratory tract infection, thyroid problems, and acid reflux as significant risk factors for the development of VPs in the current cohort of teachers.
Current results suggest that teachers develop VPs due to multiple risk factors. These factors may be either biological, psychomotor, or environment-related factors. A holistic approach (which could include educating teachers about voice care during their training, and if they develop VP during their career, then managing the VP by taking into consideration different risk factors) addressing all these factors needs to be adopted to prevent VPs in primary school teachers.
与其他职业用嗓者相比,教师更容易出现嗓音问题(VPs)。本研究的目的是调查印度小学教师中嗓音问题的患病率及危险因素。
流行病学横断面调查。
收集了1082名教师的自填问卷数据。
在参与本研究的1082名教师中,有188名教师报告存在嗓音问题,患病率为17.4%。长时间讲话后嗓音疲劳是最常报告的症状,其次是喉咙疼痛/干燥、嗓音紧张、颈部肌肉紧张以及发声困难。调整后的优势比数值显示,教龄、教室背景噪音水平高、授课时经历心理压力、呼吸管理不当(说话时憋气)、语调焦点不佳(说话时咬紧牙关/牙齿)、上呼吸道感染、甲状腺问题以及胃酸反流是当前教师队列中出现嗓音问题的重要危险因素。
目前的结果表明,教师出现嗓音问题是由多种危险因素导致的。这些因素可能是生物学、心理运动或与环境相关的因素。需要采用一种整体方法(包括在培训期间对教师进行嗓音护理教育,如果他们在职业生涯中出现嗓音问题,则通过考虑不同的危险因素来管理嗓音问题)来解决所有这些因素,以预防小学教师出现嗓音问题。
