中文摘要
目的： 分析巴西女性教师样本中声门源声学测量与嗓音自我评估评分异常的患病率，并考虑年龄组因素。
方法： 横断面回顾性研究，纳入221名女性教师的数据库记录。收集的数据包括：病史采集、听力筛查、声门源声学嗓音测量、巴西葡萄牙语版嗓音症状量表（VoiSS）以及巴西葡萄牙语版嗓音障碍指数（VHI）。各变量依据其各自的常模标准进行二分类。对每个个体结局及汇总结局估计患病率，并采用Wilson法计算相应的95%置信区间。
结果： 所有VHI领域患病率均高于50%，所有VoiSS领域患病率均高于80%。在声学参数中，患病率高于50%的参数为：STD、SPI和VTI；高于70%的为：sPPQ、vfo、ShdB和vAm；高于80%的为：RAP、Jitt、Jita和PPQ；高于90%的为：fhi、flo、Shim、APQ、sAPQ和NHR。
结论： 在该巴西女性教师样本中，无论年龄如何，自我评估测量与声学参数均观察到嗓音障碍的高患病率。这提示该教师群体存在显著的嗓音偏差，需要开展针对嗓音健康的干预措施。
英文摘要
OBJECTIVE: To analyze the prevalence of alterations in acoustic glottic source measures and vocal self-assessment scores in a sample of Brazilian female teachers, considering age group.
METHODS: Cross-sectional and retrospective study including database records of 221 female teachers. Data collected included: anamnesis, hearing screening, acoustic glottal source vocal measures, the Brazilian Portuguese version of the Voice Symptom Scale (VoiSS), and the Brazilian Portuguese version of the Voice Handicap Index (VHI). Variables were dichotomously classified according to the normative criteria of each variable. Prevalence was estimated for each individual and aggregate outcome, with respective 95% confidence intervals calculated using the Wilson method.
RESULTS: All VHI domains showed prevalence above 50% and all VoiSS domains showed prevalence above 80%. Among the acoustic parameters, prevalence above 50% was found for: STD, SPI, and VTI; prevalence above 70% for: sPPQ, vfo, ShdB, and vAm; prevalence above 80% for: RAP, Jitt, Jita, and PPQ; and prevalence above 90% for: fhi, flo, Shim, APQ, sAPQ, and NHR.
CONCLUSION: A high prevalence of voice disorders in this sample of Brazilian female teachers was observed in both self-assessment measures and acoustic parameters, regardless of age. This suggests significant vocal deviation in this group of teachers and the need for actions aimed at vocal health.
