Abstract

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痴呆症患病率及相关因素》(Prevalence of Dementia and Associated Factors among Older Adults in Latin America during the COVID-19 Pandemic)。
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。我们的目的是分析 SARS-CoV-2 大流行期间拉美老年人痴呆症的发病率及其相关因素:在 SARS-CoV-2 大流行期间,我们开展了一项多中心第一阶段横断面观察研究。在 10 个国家对 5245 名 60 岁以上的拉美成年人进行了研究: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。我们使用了电话版蒙特利尔认知评估、"阿尔茨海默病 8 "功能和认知变化量表以及简略版耶萨维抑郁量表。我们还询问了社会人口学和封锁数据。所有评估均通过电话进行。我们使用交叉表法和χ2检验来确定不同社会人口学特征造成的损害发生率的差异,并使用二元逻辑回归来评估痴呆症与社会人口学因素之间的关联:我们发现,拉丁美洲的痴呆症患病率为 15.6%,因国家而异(阿根廷=7.83%,玻利维亚=28.5%)。与痴呆症最相关的变量是种族和年龄。这似乎与流行病无关,而是与社会和社会健康因素有关:结论:在拉丁美洲,痴呆症的患病率显著增加,这是由种族、人口和社会经济因素造成的。
