INTRODUCTION: The voice is the relevant part of the subject's identity and an important means of expression and relationship with their peers. In a study population with potentially subjects without complaints, the use of protocols is an important tool for assessment of vocal self-identified, since it captures the impression that the individual has his own voice. OBJECTIVE: To assess the prevalence of vocal self-declared. Method: From a population-based sample, 399 subjects were interviewed using a structured protocol previously validated on the history of vocal health. RESULTS: The prevalence of voice disorders in this population was 4.5% (95% CI 2.8 to 6.9). The prevalence of people with a history of voice disorder was 6% for loss of voice in speaking and 19.8% for hoarseness. Having a diagnosis of voice disorders was 0.5% currently and has vocal problems at work or when he speaks so prolonged was 4%. Women had seven times the risk of any change of voice when compared to men. In terms of age, this study showed no significant association to a specific age group and voice alteration. CONCLUSION: The results of this epidemiological study provided valuable information on the prevalence of vocal and vulnerability factors that contribute to voice disorders in the general population. These data have significant potential to support action planning and policy formulation related to the promotion and maintenance of vocal health.
