To analyze the prevalence of work-related voice disorders (WRVD) among the voice professionals.
The study protocol was registered in PROSPERO (CRD42021250121). The search was performed in the Embase, Lilacs, Medline, SCOPUS, and Web of Sciences databases. There were no limitations to the year of publication and the search included observational studies which reported data on the prevalence of dysphonia in voice professionals measured through vocal complaints, vocal self-assessment, the auditory-perceptual judgment of the voice, and laryngoscopy examinations. The critical appraisal instrument for studies reporting prevalence data was used to analyze the risk of bias of the studies. Data analysis was performed using Jamovi and R software with a significance level of 5%.
The initial search identified 561 articles, 73 of which were finally included and analyzed. The total number of participants was 63,126. Dysphonia was diagnosed in 45,996 participants based on a vocal complaint, 12,843 using vocal self-assessment, 1,254 using the auditory-perceptual judgment, and 1,683 using laryngoscopies. The prevalence of total dysphonia was 44.0 (95% CI 38.47; 49.69). The prevalence of vocal complaints was 43.9% (95% CI 37.37; 50.52), 42.5% (95% CI 28.57; 57.08) for self-assessment, 53.0% (95% CI 29.87; 77.19) for auditory-perceptual judgment, and 36.9% (95% CI 18.62; 57.08) for laryngoscopic examination. In the auditory-perceptual judgment, voice professionals in class 3 (moderate quality, high demand) had a higher prevalence of dysphonia than those in class 4 (moderate quality, moderate demand) (P = 0.04). In the auditory-perceptual judgment (P = 0.04), there was a higher prevalence of dysphonia in teachers than among other voice professionals non-teachers, and in the laryngeal evaluation, no differences were found between professionals (P = 0.8).
There was a high prevalence of dysphonia in voice professionals, especially in the detection by auditory-perceptual judgment. High vocal demand and being a teacher influenced the increase in the prevalence of WRVD.
分析嗓音职业者中与工作相关的嗓音障碍（WRVD）的患病率。
该研究方案已在PROSPERO（CRD42021250121）注册。检索在Embase、Lilacs、Medline、SCOPUS和Web of Sciences数据库中进行。对发表年份无限制，检索包括观察性研究，这些研究报告了通过嗓音主诉、嗓音自我评估、嗓音的听觉-感知判断和喉镜检查来测量嗓音职业者中发声障碍患病率的数据。使用报告患病率数据的研究的关键评估工具来分析研究的偏倚风险。使用Jamovi和R软件进行数据分析，显著性水平为5%。
初步检索确定了561篇文章，最终纳入并分析了其中73篇。参与者总数为63126人。基于嗓音主诉，45996名参与者被诊断为发声障碍，12843名通过嗓音自我评估，1254名通过听觉-感知判断，1683名通过喉镜检查。总发声障碍的患病率为44.0（95%可信区间38.47；49.69）。嗓音主诉的患病率为43.9%（95%可信区间37.37；50.52），自我评估为42.5%（95%可信区间28.57；57.08），听觉-感知判断为53.0%（95%可信区间29.87；77.19），喉镜检查为36.9%（95%可信区间18.62；57.08）。在听觉-感知判断中，3级（中等质量，高需求）的嗓音职业者发声障碍的患病率高于4级（中等质量，中等需求）的嗓音职业者（P = 0.04）。在听觉-感知判断中（P = 0.04），教师发声障碍的患病率高于其他非教师嗓音职业者，在喉镜评估中，各职业者之间未发现差异（P = 0.8）。
嗓音职业者中发声障碍的患病率较高，尤其是通过听觉-感知判断检测时。高嗓音需求和身为教师会影响WRVD患病率的增加。
