dc.description<p>Purpose: The purpose of this study was to estimate the prevalence of cognitive impairment and explore its association with hearing loss and other socio-demographic and clinical risk factors, using an objective measurement of hearing levels, in adults over 50 years of age. Method: A population-based survey was completed in Santiago, Chile between December 2019 and March 2020. Participants were screened for cognitive impairment using the Short Chilean Mini-Mental State Examination and hearing levels were assessed with tonal audiometry (hearTest). Data on demographic, socioeconomic, and clinical characteristics were collected. Results: A total of 538 persons completed the assessment. The prevalence of cognitive impairment in the 50+ population was 9.3% (95% confidence interval [CI] [5.8, 14.7]). Cognitive impairment was significantly higher in individuals with any level of hearing loss (odds ratio [OR] = 2.19, 95% CI [1.00, 4.80], adjusted for age, sex, education, socioeconomic position [SEP], and head trauma). Subjects with hearing loss and who reported any use of hearing aids (16% of the sample) had a lower risk of cognitive impairment (OR of nonusers 3.64, 95% CI [1.00, 13.28], adjusted for age, sex, education, SEP, and head trauma). Conclusion: Strategies for addressing cognitive impairment should further explore the integration of early diagnosis of hearing loss and the regular use of hearing aids.</p>eng
