    Abstract:
    OBJECTIVE: This study aims to evaluate the risk factors associated with the incidence of common mental disorders (CMD) in teachers, particularly the possible relationship with voice disorders. MATERIAL AND METHODS: A longitudinal quantitative study of 469 teachers of the municipal schools of Pelotas in Brazil was conducted over three years after a baseline interview. The symptoms of CMD were assessed with the Self-Reporting Questionnaire 20 items (SRQ-20 scale) and the voice disorder was assessed with the Voice Handicap Index Protocol with cutoff of 19 points. A bivariate analysis was performed using Poisson regression to verify the difference in proportion of the incidence of CMD in the different categories of independent variables. RESULTS: The incidence of CMD was 18% (N = 265). In the bivariate analysis, the risk for CMD was 77% higher for teachers who presented with a voice disorder (RR 1.77 95% CI 1.04 to 3.03). CONCLUSIONS: Teachers who reported a voice disorder had an increased risk of developing a CMD.
