Vocal Fatigue, Dysphonia Risk, and Associated Factors in Male Brazilian Evangelical Pastors

Abstract

ObjectivesTo identify the presence of vocal fatigue and dysphonia risk in evangelical pastors and to verify associations of vocal fatigue with dysphonia risk and other factors. Study DesignCross-sectional observational study. MethodsNinety-two evangelical pastors, professionally active, answered an on-line questionnaire divided in three steps. The first step consisted of data for the characterization of the sample. In the second stage, participants answered the vocal fatigue index questionnaire (VFI). Finally, they answered to the Brazilian Dysphonia Screening tool. A descriptive analysis of the data was performed along with Spearman’s Correlation test between VFI factors and the three possible decision rules for the Brazilian Dysphonia Screening tool. A linear regression model was designed to verify predictive variables associated with the outcome “vocal fatigue”. ResultsNinety male individuals were included. The average sample was off the threshold scores of tiredness and voice impairment, physical discomfort, improvement of voice symptoms with rest, and the total score of VFI. The dysphonia risk was low and was weakly negatively correlated with the improvement of voice symptoms with rest. The linear regression indicated that the presence of a current vocal complaint increases about four points in the VFI. ConclusionEvangelical pastors present symptomatology of vocal fatigue and low risk for dysphonia. However, the greater the improvement of voice symptoms with rest, the lower the risk for dysphonia. Furthermore, the presence of a current vocal complaint is associated with increased symptoms of vocal fatigue.
