CRUZ, Mariana Sodário et al. Prevalence of self-reported hearing loss and attributed causes: a population-based study. Cad. Saúde Pública [online]. 2009, vol.25, n.5, pp. 1123-1131. ISSN 1678-4464. http://dx.doi.org/10.1590/S0102-311X2009000500019.
The objective was to determine the prevalence of self-reported hearing loss in four urban areas in São Paulo State, Brazil, and to describe the causes and socio-demographic variables. This was a population-based cross-sectional study with data on individuals 12 years or older living in the areas in 2001 and 2002. Participation included 5,250 subjects selected by two-stage probability sampling, stratified in clusters. Data analysis was exploratory, including bivariate and multiple logistic regression analysis. Prevalence of hearing loss was 5.21%, and higher levels were associated with: age > 59 years (18.7%), illness in the 15 days prior to the interview (8.4%), common mental disorders (8.8%), and use of medication in the previous 3 days (8.4%). The study of factors associated with hearing loss can lead to health interventions for addressing that the population's real needs, mostly in primary care. More population-based studies on hearing are needed in Brazil, since there are few publications on the subject.
