Hearing is essential for the processing of acoustic information and the understanding of speech signals. Hearing loss may be associated with cognitive decline, depression and reduced functionality.

To analyze the prevalence of hearing complaints in elderly individuals from Rio Grande do Sul and describe the profile of the study participants with and without hearing complaints.

7315 elderly individuals interviewed in their homes, in 59 cities in the state of Rio Grande do Sul, Brazil, participated in the study. Inclusion criteria were age 60 years or older and answering the question on auditory self-perception. For statistical purposes, the chi-square test and logistic regression were performed to assess the correlations between variables.

139 elderly individuals who did not answer the question on auditory self-perception and 9 who self-reported hearing loss were excluded, totaling 7167 elderly participants. Hearing loss complaint rate was 28% (2011) among the elderly, showing differences between genders, ethnicity, income, and social participation. The mean age of the elderly without hearing complaints was 69.44 (±6.91) and among those with complaint, 72.8 (±7.75) years. Elderly individuals without hearing complaints had 5.10 (±3.78) years of formal education compared to 4.48 (±3.49) years among those who had complaints. Multiple logistic regression observed that protective factors for hearing complaints were: higher level of schooling, contributing to the family income and having received health care in the last six months. Risk factors for hearing complaints were: older age, male gender, experiencing difficulty in leaving home and carrying out social activities.

Among the elderly population of the state of Rio Grande do Sul, the prevalence of hearing complaints reached 28%. The complaint is more often present in elderly men who did not participate in the generation of family income, who did not receive health care, performed social and community activities, had a lower level of schooling and were older.
