This study evaluated the prevalence of voice problems in kindergarten teachers and investigated some background factors affecting vocal health.
One hundred and nineteen female kindergarten teachers volunteered by responding to an Internet questionnaire on voice habits, voice symptoms, and the amount of negative impact various working conditions may have on their voices. Phoniatric examination was carried out with a rigid laryngoscope.
Of the subjects, 71.5% reported frequent strain on the voice (monthly or more often), and 56.3% reported hoarseness without infection. Eighty-six percent reported that when their voice got tired during the working day it recovered quite well, well or remarkably well by the next day. Noise at work was considered most detrimental to the voice. Clear organic findings were observed in 10.9% of the cases and did not correlate with subjective voice symptoms.
The results confirmed earlier findings that a remarkable number of kindergarten teachers suffer from voice problems and consider noise in the environment especially to be harmful to their voices. However, the majority reported recovering well from vocal symptoms. Further studies are needed on individual speech habits, working day-related voice evaluation, recovery time and work-environmental factors. A follow-up is warranted to identify the main factors leading to voice problems.
本研究评估幼儿园教师嗓音问题的患病率，并调查影响嗓音健康的一些背景因素。
119名幼儿园女教师通过回复一份关于嗓音习惯、嗓音症状以及各种工作条件可能对其嗓音产生的负面影响程度的网络问卷自愿参与。使用硬性喉镜进行嗓音科检查。
在这些受试者中，71.5%报告嗓音频繁紧张（每月或更频繁），56.3%报告无感染情况下的声音嘶哑。86%报告在工作日嗓音疲劳时，到第二天嗓音恢复得相当好、好或非常好。工作中的噪音被认为对嗓音危害最大。10.9%的病例观察到明显的器质性病变，且与主观嗓音症状无关。
结果证实了早期的研究发现，即相当数量的幼儿园教师存在嗓音问题，并且认为环境中的噪音尤其对其嗓音有害。然而，大多数人报告嗓音症状恢复良好。需要进一步研究个体的言语习惯、与工作日相关的嗓音评估、恢复时间以及工作环境因素。有必要进行随访以确定导致嗓音问题的主要因素。
