Purpose: To investigate the prevalence of hearing loss in school children detected by hearing screening in São Luís do Quitunde / AL.

The research was initiated with the application of a questionnaire and then was performed otoscopy. The hearing screening was composed by tympanometry and otoacoustic emissions evoked by transient stimulation. Students who failed one or more procedures were referred to an examination with otorhinolaringologist, and after medical management, underwent complete audiological evaluation. Statistical analysis were linked by using the chi-square test and multivariate analysis, the results of hearing screening and diagnostic evaluation with the variables age, sex, length of breastfeeding and ear. From the Pearson coefficient, we studied the correlation between variables and the odds ratio was used to study and the relative risk association between two events. Results: Of the 190 students, 27 (14.2%) had some type of hearing impairment, and the conductive the most frequent (13.2%, n = 25), followed by sensorineural hearing loss (7.4% , n = 2). Factors that indicate a higher risk for hearing loss was the short period of breastfeeding and history of middle ear infection. The male children were 1.9 more likely to have hearing loss than those of females. Conclusion: The prevalence of hearing loss in children from the city of Sao Luis do Quitunde was 14.2% (n = 27). Of the 190 children participating in this study, 33.2% failed the hearing screening at school, 19.5% due to obstruction in the ear canal and 13.7% due to failure at a minimum the procedures of screening.
