Introduction: Studies to understand the vocal profile of a population are important to plan collective health measures. The prevalence of vocal symptoms can be indicative of vocal disorder and must be investigated to support measures to prevent vocal diseases.
Aim: To characterize vocal symptoms in college students and their possible causes, and to analyze the association between hoarseness, vocal fatigue, phlegm, and burning in the throat with the possible causes mentioned.
Method: Prospective study of 517 students who answered a questionnaire about their general heath and vocal symptoms and causes. We used the study of proportions, measures of central tendency, and a chi-square test to associate the presence of symptoms and possible causes.
Results: Symptoms most often mentioned: dry mouth (21%), dry throat (18.2%), phlegm (17.9%). Causes most often cited: high respiratory disease (39%), intense voice use (24%), smoking (24%). Hoarseness was associated with heavy use of voice and high respiratory disease; vocal fatigue with intense voice use, stress, and digestive problems; burning in the throat with intensive voice use, high respiratory disease, and pollution; phlegm with smoking, and upper respiratory and digestive problems.
Conclusion: Not only do aspects of health and the voice interfere with its production, the external environment and habits influence the vocal symptoms of this population as well.
