Advanced Activities of Daily Living (AADL) and cognitive performance among older adults

This study aimed to investigate the association between advanced activities of daily living (AADL) and cognitive performance in a community of dwelling older adults participants of the FIBRA study in Ermelino Matarazzo, São Paulo. 302 older adults without cognitive decline, classified as very active or little active in AADLs, were assessed by the Mini-Mental State Examination (MMSE), Brief Cognitive Screening Battery (BCSB), Verbal Fluency (VF), Clock Drawing Test (CDT), and Geriatric Depression Scale (GDS). The AADLs were associated with performance in the MMSE and CDT in univariate analyses, but the association lost statistical significance in the multivariate model. The MMSE score was associated with age, education, sex and depression symptoms. The CDT score was associated with education. The association between AADLs and cognitive performance seems to be modulated by socio-demographic variables and the number of depression symptoms.本研究旨在探究位于巴西圣保罗州埃尔梅利诺·马塔拉佐（Ermelino Matarazzo）的FIBRA研究项目中的社区居住老年参与者的高级日常生活活动（Advanced Activities of Daily Living，AADL）与认知表现之间的关联。本研究共纳入302名无认知衰退的老年受试者，依据其AADL活动活跃度被分为高活跃组与低活跃组，并采用简易精神状态检查表（Mini-Mental State Examination，MMSE）、简短认知筛查量表（Brief Cognitive Screening Battery，BCSB）、言语流畅性测试（Verbal Fluency，VF）、画钟测验（Clock Drawing Test，CDT）以及老年抑郁量表（Geriatric Depression Scale，GDS）对受试者进行评估。单因素分析结果显示，AADL与MMSE及CDT的测试得分存在关联，但该关联在多因素模型中不再具有统计学显著性。MMSE得分与年龄、受教育程度、性别及抑郁症状存在关联；CDT得分则与受教育程度相关。AADL与认知表现之间的关联似乎受到社会人口学变量以及抑郁症状数量的调节。
