Objective Determining the prevalence of alterations in informal workers’ audition, respiratory and vocal functions and their association with certain risk factors in Popayan, Colombia. Methods This was a descriptive, cross-sectional study of 186 informal workers (i.e. people selling things in the street). After signing an informed consent form, an interview was held to obtain data regarding sociodemographic and communicative variables. The workers were then evaluated using tests for tone audiometry, respiratory function and Wilson's voice profile. SPSS (v.19.0) was used for statistical analysis. Results Being older than 30 years of age (OR 5.84: 2.85-12.00 95%CI), having a poor educational level (2.81: 1.22-6.44 95%CI) and low socioeconomic status (4.54:1.89-10.91 95%CI) and prolonged working hours (2.64: 1.27-5.06 95%CI) were associated with auditive function disorders. Respiratory function disorders were associated with being female (1.83; 1.00-3.34 95%CI) and having prolonged working hours (2.04: 1.11-3.74 95%CI). Regarding vocal function, being over 30 years-old (3.36: 1.33-3.51 95%CI) and having a low educational level (3.67; 1.05-12.76 95%CI) were risk factors. Communicative factors related to auditive, respiratory and voice disorder were ear pain, hypertrophic tonsils, trauma, gastro-esophageal reflux, frequent cough, strong emotions and screaming. Conclusions It is evident that alterations in informal workers’ communicative system are associated with certain sociodemographic and communicative risk factors. This information provides a baseline for improving healthcare promotion and disease prevention strategies aimed at this population.
