Background: The COVID-19 pandemic has had a great impact on cognitive health in Latin American older adults, increasing the risk of cognitive impairment and dementia. Our objective was to analyze the prevalence of dementia and the associated factors in Latin American older adults during SARS-CoV-2 pandemic. Methods: A multicentric first phase cross-sectional observational study was conducted during the SARS-CoV-2 pandemic. Five thousand two hundred and forty-five Latin American adults over 60 years of age were studied in 10 countries: Argentina, Bolivia, Chile, Colombia, Ecuador, Guatemala, Mexico, Peru, the Dominican Republic, and Venezuela. We used the telephone version of Montreal Cognitive Assessment, the “Alzheimer Disease 8” scale for functional and cognitive changes, and the abbreviated version of the Yesavage depression scale. We also asked for sociodemographic and lockdown data. All the evaluation was made by telephone. Cross-tabulations and χ2 tests were used to determine the variability of the prevalence of impairment by sociodemographic characteristics and binary logistic regression to assess the association between dementia and sociodemographic factors. Results: We observed that the prevalence of dementia in Latin America is 15.6%, varying depending on the country (Argentine = 7.83 and Bolivia = 28.5%). The variables most associated with dementia were race and age. It does not seem to be associated with the pandemic but with social and socio-health factors. Conclusion: The prevalence of dementia shows a significant increase in Latin America, attributable to a constellation of ethnic, demographic, and socioeconomic factors.

Introducción La detección de síntomas de ansiedad entre el personal sanitario que atiende a pacientes contagiados de COVID-19 es una prioridad actual. Se requieren instrumentos rápidos y válidos para esta población. El objetivo es establecer la validez de constructo y la confiabilidad de la Escala de Ansiedad Generalizada (GAD-7) en médicos colombianos durante la cuarentena por la COVID-19. Métodos Estudio eSalud, en el que se recopilaron datos transversales en línea (n = 1.030) de 610 médicos de COVID y 420 no de COVID durante la cuarentena colombiana, entre el 20 de abril y el 10 de agosto de 2020. Se contactó con cada sujeto, que confirmó participación, identidad y función profesional. Resultados Se encontró una estructura factorial de 1 solo factor, conformado por los 7 ítems del instrumento, que logró explicar el 70% de la varianza. Los índices de bondad de ajuste (RMSEA = 0,080; CFI = 0,995; SRMR = 0,053; p 0,07. Por último, la consistencia interna del instrumento fue buena, con alfa de Cronbach = 0,920 (IC95%, 8,80-9,71). Conclusiones El GAD-7 es un instrumento que presenta indicadores adecuados de validez y confiabilidad. Es un excelente instrumento, confiable, fácil y rápido de usar para la detección de los síntomas de ansiedad generalizada en personal médico, atienda o no a pacientes contagiados de COVID-19.

In Latin America, the volume of care of infected patients, higher presence of comorbidities among older adults, and restricted access to clinical controls have become this age group into one with the highest risk (Dubey etal , 2020) [ ]a Consortium of universities, research centers, and clinical centers have joined forces to carry out research which seeks to know the emotional state of Latin American older adults during confinement by Coronavirus disease (COVID-19) The protocol we used includes a sociodemographic and clinical questionnaire, information on confinement, lifestyles, and the abbreviated version of the Yesavage Geriatric Depression Scale (Martinez de la Iglesia etal , 2020)
