The COVID-19 pandemic in Brazil affected the lives of singers, with negative impacts of the disease on the voice, such as dysphonia and throat clearing. This study aims to evaluate the presence of dysphonia and throat clearing in singers during the COVID-19 pandemic in Brazil.
This is a cross-sectional analytical study with a sample of 154 singers from all over Brazil. Data collection was carried out online, by completing the questionnaire created by the researcher using Google Forms. The following were considered the outcome variables: voice impairment and throat clearing. The bivariate analysis was performed to test the relationship between COVID-19 infection and voice impairment, COVID-19 infection and throat clearing, COVID-19 infection and laryngeal complaints (voice impairment and throat clearing).
In this study, the mean age of the singers was 35.8 (Standard deviation = ±10.2 years) and 59.2% were female. Most of them worked as professional singers (81.1%) and had more than 10 years of professional experience (57.4%), mainly singing pop music (85.4%). A total of 62% reported vocal alterations during the COVID-19 infection and 53% had vocal alterations after the infection, with 44.0% reporting the onset of throat clearing after the infection. There was a significant association between COVID-19 infection and having voice impairment (P = 0.03; prevalence ratio - PR: 2.33; CI: 1.04-5.46). An association was observed between the onset of throat clearing and the occurrence of COVID-19 infection (P = 0.001; PR: 9.13; CI: 2.47-64.42).
The results indicated that there is an association between COVID-19 infection and complaints of dysphonia and throat clearing in Brazilian singers. This study demonstrates the importance of guidance to singers infected with COVID-19 by health voice processionals.
巴西的新冠疫情影响了歌手的生活，该疾病对嗓音产生了负面影响，如发声困难和清嗓。本研究旨在评估巴西新冠疫情期间歌手发声困难和清嗓的情况。
这是一项横断面分析研究，样本来自巴西各地的154名歌手。通过使用谷歌表单完成研究者创建的问卷进行在线数据收集。以下被视为结果变量：嗓音障碍和清嗓。进行双变量分析以检验新冠感染与嗓音障碍、新冠感染与清嗓、新冠感染与喉部症状（嗓音障碍和清嗓）之间的关系。
在本研究中，歌手的平均年龄为35.8岁（标准差 = ±10.2岁），59.2%为女性。他们大多为职业歌手（81.1%），拥有超过10年的专业经验（57.4%），主要演唱流行音乐（85.4%）。共有62%的人报告在新冠感染期间出现嗓音改变，53%的人在感染后出现嗓音改变，44.0%的人报告在感染后开始清嗓。新冠感染与嗓音障碍之间存在显著关联（P = 0.03；患病率比 - PR：2.33；CI：1.04 - 5.46）。观察到清嗓的开始与新冠感染的发生之间存在关联（P = 0.001；PR：9.13；CI：2.47 - 64.42）。
结果表明，巴西歌手的新冠感染与发声困难和清嗓症状之间存在关联。本研究证明了健康嗓音专业人员对感染新冠的歌手进行指导的重要性。
