Respiratory Tract Infections and Voice Quality in 4-Year-old Children in the STEPS Study

摘要

Objectives. Health-related factors are part of the multifactorial background of dysphonia in children. Respiratory tract infections affect the same systems and structures that are used for voice production. The purpose of this study was to investigate if the number of respiratory tract infections or the viral etiology were significant predictors for a more hoarse voice quality.
