Summary: | ABSTRACT Objective: to analyze the association between voice disorder and aspects related to breathing mode in children, according to sex. Methods: 250 children, aged six to nine years, attending a public school in São Paulo city, were selected. The collection consisted of spontaneously audio recorded speech samples. The breathing mode was evaluated for lip resting posture and nasal flow. Three audiologists performed the perceptual evaluation of the voice quality, with the help of GIRBAS scale. The results were associated using the chi-square test (p = 0.05). Results: 50.4% females and 49.6% males. As for the overall grade (G), 12.8% had voice disorder with respect to voice quality. In the breathing mode, 36.8% presented alterations in lip posture and 71.2%, in nasal flow. The associations between voice disorder and gender (p = 0.96), lip posture (p = 0.38) and nasal flow (p = 0.18) and between alterations in the nasal flow and sex (p = 0.449) were not confirmed. The association between lip posture and sex revealed significant differences in favor of males (p = 0.003). Conclusion: there was no statistically significant difference associating voice disorders with breathing mode (lip posture and nasal flow) and gender.
RESUMO Objetivo: analisar a associação entre distúrbio de voz e aspectos referentes ao modo respiratório, em crianças, segundo sexo. Métodos: foram selecionadas 250 crianças, na faixa etária de seis a nove anos, de uma escola pública da cidade de São Paulo. A coleta constou de amostras áudio gravadas de fala espontânea. O modo respiratório foi avaliado quanto à postura de lábios e fluxo nasal. Três juízas fonoaudiólogas realizaram a avaliação perceptivo-auditiva das vozes quanto à qualidade vocal, com o auxílio da escala GIRBAS. Os achados foram associados, utilizando-se o teste do qui-quadrado (p=0,05). Resultados: 50,4% do sexo feminino e 49,6% sexo masculino. Quanto ao grau geral (G), 12,8% apresentaram distúrbio de voz com relação à qualidade vocal. No modo respiratório, 36,8% apresentaram alteração quanto à postura labial e 71,2%, quanto ao fluxo nasal. Não foi confirmada a associação entre distúrbio da voz e sexo (p=0,96), postura de lábios (p=0,38) e fluxo nasal (p=0,18), assim como entre alteração do fluxo nasal e sexo (p=0,449). A associação entre postura labial e sexo evidenciou diferença significativa a favor do masculino (p=0,003). Conclusão: não houve associação entre o distúrbio de voz e a alteração da respiração, contudo, houve |
