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.

COVID-19 大流行期间拉丁美洲老年人的痴呆症患病率和相关因素

背景: COVID-19 大流行对拉丁美洲老年人的认知健康产生了巨大影响,增加了认知障碍和痴呆症的风险。我们的目标是分析 SARS-CoV-2 大流行期间拉丁美洲老年人的痴呆症患病率和相关因素。方法:在 SARS-CoV-2 大流行期间进行了一项多中心的第一阶段横断面观察研究。在以下 10 个国家/地区对 5245 名 60 岁以上的拉丁美洲成年人进行了研究:阿根廷、玻利维亚、智利、哥伦比亚、厄瓜多尔、危地马拉、墨西哥、秘鲁、多米尼加共和国和委内瑞拉。我们使用了蒙特利尔认知评估的电话版本、用于功能和认知变化的“阿尔茨海默病 8”量表以及 Yesavage 抑郁量表的缩写版本。我们还要求提供社会人口和锁定数据。所有评估均通过电话进行。交叉表和 χ 2测试用于通过社会人口学特征和二元逻辑回归来确定损害患病率的变异性,以评估痴呆症和社会人口学因素之间的关联。结果:我们观察到拉丁美洲痴呆症的患病率为 15.6%,因国家/地区而异(阿根廷 = 7.83,玻利维亚 = 28.5%)。与痴呆最相关的变量是种族和年龄。它似乎与流行病无关,但与社会和社会健康因素有关。结论:由于种族、人口和社会经济因素的影响,拉丁美洲的痴呆症患病率显着增加。
