Abstract

Objective: To analyze the sociodemographic and health characteristics of deaf Brazilian Sign Language (LIBRAS) users compared with non-users. Methodology: A cross-sectional descriptive epidemiological study was conducted with a non-probabilistic intentional sample. Data were collected by a self-reported and online questionnaire and underwent stratified analyses by subgroups of interest using Fisher’s exact test and Odds Ratios. Results: Most study participants communicated using LIBRAS. Deaf non-sign language users had a higher schooling level compared with sign language users. We observed a higher proportion of employed men and unemployed women. Results highlight the linguistic barriers experienced by deaf sign language users regarding limitations in accessing health information about self-care and treatment. Conclusion: We found no statistically significant differences when comparing the sociodemographic and health characteristics between the groups of deaf LIBRAS users and non-users, except with regard to education and employment. Although not being a population-based study, these findings provide input for developing public policies aimed at deaf people in the region studied.
