Abstract
PURPOSE The purpose of this study was to estimate the prevalence of cognitive impairment and explore its association with hearing loss and other sociodemographic 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.

Abstract
Introduction: Little is known about risk factors of dementia in Latin American countries. We aimed to identify socio–demographic, health and lifestyle risk factors of incident dementia in Cuban older adults. Methods: Data were from 1,846 participants in the Cuban cohort of the 10/66 Dementia Research Group. Participants completed questionnaires, health examinations, and cognitive tests at baseline (2003–2006) and 4.5 years later (2007–2010). Associations between risk factors (baseline) and incident dementia (follow-up) were examined using logistic regression. Results: Just over 9% of participants developed dementia. Overall, older age and low physical activity were associated with incident dementia. In those 65–74 years of age, depression, stroke and low physical activity were associated with incident dementia. In those ≥75 years of age, low physical activity, never eating fish, and smoking were associated with incident dementia. Conclusions: Modifiable lifestyle factors play an important role in developing dementia in Cuban older adults. This knowledge opens up opportunities for preventive strategies.
