Voice disorders are considered to be more common among teachers than other occupations. However, epidemiological data are scarce and only a few researchers have studied stress as a risk factor in voice disorders in teachers. This paper presents data from a study on Finnish school teachers which investigated the prevalence of voice disorders and evaluated the risk factors for voice disorders, especially stress.
A cross-sectional study was conducted among primary and secondary education teachers across Finland.
Voice disorders were assessed with a seven-item voice questionnaire and stress at work was measured with a validated single-item question.
The prevalence of voice disorders over the 12-month period was 54% in the sample of 1198 primary and secondary education teachers in Finland. Of the teachers, 81% were female, and they suffered more voice disorders than the males. Stress was the most significant explanatory variable with a 3.6-fold risk as regards voice disorders. The association between voice disorders and stress was even stronger than that of asthma, asthma medication, and allergic rhinitis, which are known to cause serious risks for voice disorders in general.
Our results hypothesize that stress may be a multi-dimensional problem associated with various risk factors and result in an even more urgent risk of voice disorders in teachers than estimated. Longitudinal research is needed to investigate the causality between voice disorders and stress among teachers. In addition, it is recommended that in the occupational health care of teachers' consideration should be given to the fact that voice disorders and stress may have a multi-dimensional association.
嗓音障碍被认为比其他职业更为常见于教师群体中。然而，流行病学数据有限，仅有少数研究人员将压力作为教师嗓音障碍的一个风险因素进行了研究。本文呈现了一项针对芬兰学校教师的研究数据，该研究调查了嗓音障碍的流行情况，并评估了嗓音障碍的风险因素，尤其是压力。
这是一项在芬兰各地进行的针对小学和中学教育教师的横断面研究。
使用一个包含七个项目的嗓音问卷评估嗓音障碍，使用一个经验证的单项问题评估工作压力。
在芬兰的 1198 名小学和中学教育教师样本中，过去 12 个月的嗓音障碍患病率为 54%。其中 81%为女性，她们比男性更容易出现嗓音障碍。压力是最显著的解释变量，嗓音障碍的风险是其 3.6 倍。嗓音障碍与压力之间的关联甚至比哮喘、哮喘药物和过敏性鼻炎更为密切，后两者通常被认为是嗓音障碍的严重风险因素。
我们的研究结果假设压力可能是与多种风险因素相关的多维问题，导致教师嗓音障碍的风险比预期更为紧迫。需要进行纵向研究来调查教师嗓音障碍与压力之间的因果关系。此外，建议在教师职业保健中考虑到嗓音障碍和压力可能具有多维关联的事实。
