To compare the self-perception of vocal fatigue and insomnia severity between teachers at risk and not at risk for dysphonia and between men and women.
The study included 120 female and 80 male teachers from various teaching levels. All participants completed self-assessment questionnaires on their working conditions, the Screening Index for Voice Disorder (SIVD), the Vocal Fatigue Index (VFI), and the Insomnia Severity Index (ISI). Teachers were grouped into those at risk (DG) and not at risk for dysphonia (NDG).
Both DG and NDG reported noise, stress, and dust in the work environment. These factors were more frequent in DG, which also scored above the cutoff for all VFI factors, while NDG scored high in Factor I and the total score but scored below the cutoff in Factor IV. Analysis per gender revealed no difference between DG and NDG among males, except for Factor IV. Among females, Factor IV scores were above the cutoff in DG. ISI indicated all participants had subthreshold insomnia.
Teachers often had symptoms of vocal fatigue and subthreshold insomnia regardless of the risk for dysphonia. However, DG teachers had higher scores on both protocols. Also, DG females recovered from vocal fatigue symptoms after vocal rest, unlike their counterparts who were not at risk. Both DG and NDG males and females experienced vocal fatigue and limitations, but only those at risk recovered after vocal rest.
比较有嗓音障碍风险和无嗓音障碍风险的教师之间以及男性和女性之间的嗓音疲劳自我认知和失眠严重程度。
该研究纳入了来自不同教学水平的120名女教师和80名男教师。所有参与者完成了关于其工作条件、嗓音障碍筛查指数（SIVD）、嗓音疲劳指数（VFI）和失眠严重程度指数（ISI）的自我评估问卷。教师被分为有嗓音障碍风险组（DG）和无嗓音障碍风险组（NDG）。
DG组和NDG组均报告工作环境中有噪音、压力和灰尘。这些因素在DG组中更常见，DG组在所有VFI因子上的得分也高于临界值，而NDG组在因子I和总分上得分较高，但在因子IV上得分低于临界值。按性别分析显示，男性中DG组和NDG组之间除因子IV外无差异。在女性中，DG组的因子IV得分高于临界值。ISI表明所有参与者都有亚阈值失眠。
无论有无嗓音障碍风险，教师经常有嗓音疲劳和亚阈值失眠的症状。然而，DG组教师在两项指标上得分更高。此外，与无风险的女性教师不同，DG组女性教师在嗓音休息后从嗓音疲劳症状中恢复。DG组和NDG组的男性和女性都经历了嗓音疲劳和嗓音受限，但只有有风险的人在嗓音休息后恢复。
