Purpose The prevalence of dementia has increased in recent years and, along with hearing loss, can negatively impact the health of older adults. The purpose of this retrospective cross-sectional study was to establish self-reported hearing loss and associated factors in older adults at a memory clinic. Method Researchers conducted a retrospective cross-sectional study on factors associated with self-reported hearing loss (i.e., lifestyle, general health, cognition, functional capacity). Data were taken from medical records of older adults (≥ 60 years old) who received care between 2017 and 2018 at a memory clinic located at the Southern Santa Catarina University in Brazil. Analysis included the Pearson chi-squared test and logistic regression, estimation of the crude and adjusted odds ratios (OR), with respective confidence intervals of 95%. Results Researchers analyzed the medical records of 257 older adults and verified a prevalence of 13.2% of these adults with self-reported hearing loss. There was a higher prevalence of the outcome (i.e., self-reported hearing loss) in older adults who reported tinnitus (35.2%), those with mild cognitive impairment (14.7%), and those who were sedentary (19.2%). After adjustment for confusion factors, tinnitus (OR = 4.63; p = .019) and sedentarism (OR = 2.89; p = .029) were still associated with the outcome. Conclusions Tinnitus and sedentarism were associated with hearing loss in older adults receiving care at a memory clinic. As a public health issue, presbycusis needs to be included in the health planning and health promotion agendas, with effective control, prevention, and treatment measures.
