Summary
Objective
To analyze the contribution of organizational, environmental, and personal factors
in predicting dysphonia in professional voice users.
Study Design
This was a cross-sectional documentary study.
Methods
The study sample consisted of 128 professional voice users (104 female and 24 male),
with a mean age of 39.3 years. Dysphonia (laryngeal disorder associated with vocal
complaints) was defined as the dependent variable. Organizational, environmental,
and personal factors were defined as independent variables. Logistic regression models
were used as predictive methods for data analysis. Evaluation and interpretation of
the final model were performed using the ROC curve, odds ratio, and probability estimation.
Results
Professional voice users exposed to low humidity and who talked a lot on their phones
were less likely to be dysphonic than individuals who were not exposed to these factors.
Those exposed to excessive vocal demand and who reported talking with effort were
more likely to be dysphonic than those who were not exposed to these factors. The
accuracy of the prediction model was 80.8%.
Conclusions
Exposure to low humidity and talking a lot on the phone were protective factors. However,
excessive vocal demand and straining were risk factors for predicting the presence
of dysphonia in professional voice users with high accuracy.
