Cognition, depressive symptoms, functional capacity and frailty in institutionalized elderly

This database presents results of two research projects carried out in four Brazilian long-term institutions, 3 in the city of Rio de Janeiro (RJ) and 1 in Montes Claros (MG) between the years 2015 and 2018. The sample comprises 67 elderly, data were collected on age, sex, global cognition (Brazilian version of the Mini Mental State Examination - MEEM) (Bertolucci et al., 1994), frailty syndrome (SF) based on the criteria proposed by Fried et al. , 2001, depressive symptoms through the Brazilian version Geriatric Depression Scale (GDS) (De Sousa et al., 2007). Still, for the evaluation of memory, the tests of verbal fluency (FV) were used in order to evaluate the semantic memory and the executive function (Brucki, S. M. et al., 1997); Digit Span Forward (DSF) and Backward (DSB) to check short-term and working memory, respectively (Schroeder, R. W. et al., 2012). The inclusion criteria were: i) being a resident of a long-term institution; ii) be 60 years of age or older; iii) understand and answer commands. The exclusion criteria were: i) dependent walking; ii) severe cardiovascular and neurological diseases. Following the ethical precepts, the projects were approved by their respective Research Ethics Committees, according to the place and period of collection, which are: Research Ethics Committee of the Universidade Federal Fluminense, under the registration 1,178,067 in the year of 2015 and by the Research Ethics Committee of the State University of Montes Claros under opinion 2,398,863 in the year 2017. All participants or their guardians signed the informed consent form in accordance with resolution 466/2012 of the National Council of Health in Brazil.本数据库收录了2015至2018年间，于巴西四家长期照护机构开展的两项研究项目的成果。其中三家机构位于里约热内卢市（Rio de Janeiro，缩写RJ），剩余一家位于蒙特斯克拉鲁斯市（Montes Claros，缩写MG）。 本研究共纳入67名老年受试者，采集的基线信息包括年龄、性别；整体认知水平采用巴西版简易精神状态检查表（Mini Mental State Examination，缩写MEEM）评估（Bertolucci等，1994）；衰弱综合征（SF）依据Fried等人2001年提出的判定标准进行评定；抑郁症状则通过巴西版老年抑郁量表（Geriatric Depression Scale，缩写GDS）评估（De Sousa等，2007）。 针对记忆功能的评估，采用言语流畅性测验（verbal fluency，缩写FV）评估语义记忆与执行功能（Brucki S.M.等，1997）；分别以数字顺背测验（Digit Span Forward，缩写DSF）与数字倒背测验（Digit Span Backward，缩写DSB）评估短时记忆与工作记忆（Schroeder R.W.等，2012）。 纳入标准如下：① 为长期照护机构常住居民；② 年龄≥60周岁；③ 能够理解并响应实验指令。 排除标准如下：① 行走依赖他人辅助；② 患有严重心血管疾病或神经系统疾病。 本研究严格遵循学术伦理规范，两项研究分别经所属机构的伦理审查委员会批准：2015年，弗鲁米嫩塞联邦大学（Universidade Federal Fluminense）伦理审查委员会以登记编号1,178,067予以批准；2017年，蒙特斯克拉鲁斯州立大学（State University of Montes Claros）伦理审查委员会以审查编号2,398,863出具意见予以批准。 所有受试者或其法定监护人均已签署知情同意书，该流程符合巴西国家卫生委员会第466/2012号决议的相关规定。
