          Abstract

          RESUMO Objetivos: Identificar características de eficiência e valores de corte das dimensões do protocolo Perfil de Participação e Atividades Vocais - PPAV que discriminam disfônicos de indivíduos vocalmente saudáveis; verificar se a nota de corte permanece a mesma para uma amostra de professores. Métodos: Características de eficiência e valores de corte dos dados do PPAV de 171 indivíduos foram analisados por meio da curva ROC (Receiver Operating Characteristic curve ): 90 professores (60 disfônicos e 30 vocalmente saudáveis, com médias de idade semelhantes, p=0,418) e 81 indivíduos não professores (48 disfônicos e 33 vocalmente saudáveis, com média de idade semelhantes, p=0,934). Resultados: Os valores de área sob a curva ROC - AUC e os valores de corte do escore total do PAVV que separam indivíduos com e sem disfonia são diferentes para não professores e professores. Indivíduos não professores apresentaram AUC = 0,986 (p<0,001) e 4,5 pontos no escore total do PPAV (sensibilidade=95,8% e especificidade=90,9%); já os professores apresentaram AUC = 0,872 (p<0,001) e nota de corte de 14,6 pontos (sensibilidade=91,7% e especificidade=75,9%). Conclusão: A nota de corte do PPAV é diferente para não professores e professores, sendo maior para os professores, porém, com maior sensibilidade e especificidade para os indivíduos não professores, podendo ser utilizado para triagens de grandes populações de risco para alteração de voz.

          ABSTRACT Purpose: To identify the efficiency characteristics and cutoff values of the dimensions of the Voice Activity and Participation Profile (VAPP) protocol, which discriminates the dysphonic and vocally healthy individuals; to verify if the cutoff values remain the same for a sample of teachers. Methods: Efficiency characteristics and cutoff values of VAPP data from 171 subjects were analyzed by receiver-operating characteristic (ROC) curve: 90 teachers (60 dysphonic and 30 vocally healthy individuals, with a similar mean age, p=0.418) and 81 nonteachers (48 dysphonic and 33 vocally healthy individuals, with a similar mean age, p=0.934). Results: The area under the ROC curve (AUC) and the cutoff values of the total score of VAPP for discriminating the individuals with and without dysphonia are different for the nonteachers and teachers. The nonteachers presented AUC=0.986 (p<0.001) and 4.5 points of cutoff of the total score of VAPP (sensitivity=95.8%; specificity=90.9%); the teachers presented AUC=0.872 (p<0.001) and 14.6 points of cutoff of the total score of VAPP (sensitivity=91.7%, specificity=75.9%). Conclusion: The cutoff values of VAPP are different for the nonteachers and teachers, being higher for the teachers but with greater sensitivity and specificity for the nonteachers, and can be used to screen large populations with the risk of voice disorders.

          Prevalence of voice disorders in teachers and the general population.

          Over 3 million teachers in the United States use their voice as a primary tool of trade and are thought to be at higher risk for occupation-related voice disorders than the general population. However, estimates regarding the prevalence of voice disorders in teachers and the general population vary considerably. To determine the extent that teachers are at greater risk for voice disorders, 2,531 randomly selected participants from Iowa and Utah (1,243 teachers and 1,288 nonteachers) were interviewed by telephone using a voice disorder questionnaire. Prevalence-the number of cases per population at risk at a specific time-was determined. The prevalence of reporting a current voice problem was significantly greater in teachers compared with nonteachers (11.0% vs. 6.2%), chi(2)(1) = 18.2, p 4 weeks in duration), compared with acute voice disorders (20.9% vs. 13.3%), chi(2)(1) = 8.7, p =.003. To assess the association between past voice disorders and possible risks, adjusted odds ratios (ORs) were estimated using multiple logistic regression. The results identified that being a teacher, being a woman, being between 40 and 59 years of age, having 16 or more years of education, and having a family history of voice disorders were each positively associated with having experienced a voice disorder in the past. These results support the notion that teaching is a high-risk occupation for voice disorders. Important information is also provided regarding additional factors that might contribute to the development of voice disorders.

            Frequency and effects of teachers' voice problems.

            This study compared the frequency and effects of voice symptoms in teachers to a group of individuals employed in other occupations. Teachers were more likely to report having a voice problem (15 vs. 6%), having 10 specific voice symptoms, and having 5 symptoms of physical discomfort. They averaged almost 2 symptoms compared with none for nonteachers. Likewise, teachers were more likely to perceive that a voice problem would adversely affect their future career options, had done so in the past, and was limiting their current job performance. Over 20% of teachers but none of the nonteachers had missed any days of work due to a voice problem. These findings suggest that teaching is a high-risk occupation for voice disorders and that this health problem may have significant work-related and economic effects.
