To investigate the differences and correlation between the Voice Handicap Index-10 (VHI-10) and the Voice-Related Quality of Life (V-RQOL) in teachers in China with and without voice disorders.
This is a cross-sectional descriptive analytical study.
The participants were 864 teachers (569 women, 295 men) whose vocal cords were examined using a flexible nasofibrolaryngoscope. Questionnaire results were obtained for both the VHI-10 and the V-RQOL.
Of the 864 participants, 409 teachers had no voice disorders and 455 teachers had voice disorders. The most common voice complaint was hoarseness (n = 298) and the most common throat complaint was globus pharyngis (n = 79) in teachers with voice disorders. Chronic laryngitis (n = 218) and polyps and nodules (n = 182) were the most frequent diagnoses in teachers with voice disorders. Significant differences were seen on the VHI-10 between teachers with and those without voice disorders (P < 0.05) and in function between female and male teachers with voice disorders (P < 0.05) and between those with different voice disorders (P < 0.05). Moderate to strong correlations were observed between VHI-10 total score and those for the three domains of the VHI-10 and the V-RQOL (P < 0.0001).
There is a high prevalence of voice disorders in teachers. Teachers with voice disorders have poor voice-related quality of life, with more impairment seen among female than male teachers. Different groups of voice disorders have different effects on voice-related quality of life. A moderate correlation was found between the results of the VHI-10 and the V-RQOL.
调查中国有嗓音障碍和无嗓音障碍教师的嗓音障碍指数-10（VHI-10）与嗓音相关生活质量（V-RQOL）之间的差异及相关性。
这是一项横断面描述性分析研究。
参与者为864名教师（569名女性，295名男性），使用软性鼻咽喉镜检查其声带。获取了VHI-10和V-RQOL的问卷调查结果。
864名参与者中，409名教师无嗓音障碍，455名教师有嗓音障碍。有嗓音障碍的教师中，最常见的嗓音主诉是声音嘶哑（n = 298），最常见的咽喉主诉是咽异感症（n = 79）。慢性喉炎（n = 218）和息肉及小结节（n = 182）是有嗓音障碍教师中最常见的诊断。有嗓音障碍和无嗓音障碍的教师在VHI-10上存在显著差异（P < 0.05），有嗓音障碍的女性和男性教师在功能方面存在差异（P < 0.05），不同嗓音障碍的教师之间也存在差异（P < 0.05）。观察到VHI-10总分与VHI-10三个领域以及V-RQOL的得分之间存在中度至高度相关性（P < 0.0001）。
教师中嗓音障碍的患病率较高。有嗓音障碍的教师嗓音相关生活质量较差，女性教师比男性教师受损更严重。不同组别的嗓音障碍对嗓音相关生活质量有不同影响。发现VHI-10结果与V-RQOL之间存在中度相关性。
