To determine factors associated with chronic hoarseness in Australian group fitness instructors (GFIs).
A total of 361 GFIs (81 males, 280 females), aged between 18-67 years currently active in the Australian fitness industry, completed a 65-item self-completion questionnaire distributed via SurveyMonkey. Demographic, lifestyle and voice use variables thought to influence vocal health and voice production in the GFI population were examined using logistic regression analyses. GFIs' chronic hoarseness with response options "positive" and "negative" was considered as the outcome variable of interest.
Approximately 39% of the study participants reported having chronic hoarseness. Multivariable logistic regression modelling revealed a set of statistically significant factors associated with chronic hoarseness. These include: younger age, partial voice loss while instructing, partial voice loss after instructing and using vocal volume louder than normal speaking voice whilst instructing.
This study has identified factors associated with the presentation of chronic hoarseness in the Australian GFI population. Prospective studies are required to validate the findings of this study in order to better understand predictive factors of chronic hoarseness among GFIs.
确定与澳大利亚团体健身教练（GFIs）慢性嗓音嘶哑相关的因素。
共有361名年龄在18 - 67岁之间、目前活跃于澳大利亚健身行业的团体健身教练（81名男性，280名女性）完成了通过SurveyMonkey分发的一份包含65个条目的自填式问卷。使用逻辑回归分析来检验被认为会影响团体健身教练群体嗓音健康和发声的人口统计学、生活方式及嗓音使用变量。团体健身教练的慢性嗓音嘶哑（回答选项为“阳性”和“阴性”）被视为感兴趣的结果变量。
约39%的研究参与者报告有慢性嗓音嘶哑。多变量逻辑回归模型显示了一组与慢性嗓音嘶哑相关的具有统计学意义的因素。这些因素包括：年龄较小、授课时部分嗓音丧失、授课后部分嗓音丧失以及授课时使用的音量高于正常说话音量。
本研究确定了与澳大利亚团体健身教练群体慢性嗓音嘶哑表现相关的因素。需要进行前瞻性研究来验证本研究的结果，以便更好地了解团体健身教练中慢性嗓音嘶哑的预测因素。
