MADRID+90 study on factors associated with longevity

MADRID+90 is a multicentre, observational, two wave, cross-sectional study that will be conducted in two different waves. The present dataset corresponds specifically to Wave 1 that lasted from September 2019 to February 2020. The sample was randomly selected from the municipal census of Madrid (Spain) which includes any person living in the city. A total of 191 community-dwelling individuals aged 90 and over participated in this wave. Wave 1 surveys were conducted at the participants' homes by trained research staff. The complete visit took approximately 15 to 30 minutes. A structured questionnaire was used to collect information related to the following areas: demographic data, morbidity, medication, subjective cognitive decline, Spanish version of the Telephone Interview for Cognitive Status (TICS), perceived health, quality of life, functional dependence, and lifestyle habits. The responses of the participants, and the proxies when appropriate, were directly coded in electronic devices, so that the information was uploaded directly into the database.MADRID+90是一项多中心、观察性两波次横断面研究，计划分两个独立调查波次开展。本数据集特指2019年9月至2020年2月实施的第一波次调查数据。研究样本从西班牙马德里市户籍登记系统中随机抽取，覆盖所有居住于该市的人群。本波次共有191名社区居住的90岁及以上老年人参与。第一波次调查由经过专业培训的研究人员在参与者家中完成，单次完整访视时长约15至30分钟。研究采用结构化问卷收集以下领域的信息：人口统计学资料、疾病患病情况、用药情况、主观认知减退、西班牙语版认知状态电话访谈量表（Telephone Interview for Cognitive Status, TICS）、自评健康状况、生活质量、功能依赖情况以及生活方式习惯。参与者本人的应答以及必要时由代理人提供的应答，均直接在电子设备上完成编码与录入，信息可直接上传至研究数据库。
