H70, cohort 7: 70-year-olds born in 1944

H70 is one of the longitudinal population studies from Gothenburg where representative study samples of older people have been followed over a long period of time (metadata related to the H85, 95+ and Prospective Population Study of Women studies can be found under the Related studies tab). H70 is a population-based study of normative aging in 70 year old populations which focuses on both medical and cognitive measures. H70 started in 1971 with the recruitment of 973 70-year-olds born in 1901-02 and participants have been intermittently followed for up to 30 years. Additional birth cohorts of 70-year-olds as well as 75-year-olds have also been studied and all cohorts have been followed to some extent longitudinally. The H70 study is coordinated by several research groups, primarily Geriatrics, Primary Health Care, Psychiatry, and Epidemiology. The examination procedures at each study have been retained as identical as possible to provide results that can be compared over time. The study comprises a psychiatric interview, physical examination, a close informant interview, blood samples with extensive laboratory analysis and psychological tests. It also includes collecting data related to socioeconomic status, marital status, living conditions, housing situation, education, religion, hobbies and life events. Neurobiological investigations in the form of computed tomography (CT) and magnetic resonance imaging (MRI) of the brain and spinal puncture and analysis of brain-spinal fluid are also carried out. Register data from all the major hospitals, geriatric and psychiatric institutions and outpatient clinics in Gothenburg is evaluated to find cases of psychological and somatic diseases. Dementia, depression, psychotic disorders, sleep disorders, anxiety disorders, and post-traumatic stress disorder (PTSD) are diagnosed according to DSM-III-R and DSM-IV. Somatic diseases are classified according to established criteria. Purpose: The original aim was: 1. To contribute to the knowledge of normal ageing processes and of normal conditions within the age group 2. To make a survey of the social and medical conditions of the population. 3. To obtain basic data for planning the care of the elderly and 4. To offer the subjects a thorough medical examination A new H70 study of the birth cohort born in 1944 and living in Gothenburg is taking place during 2014-15.H70是哥德堡开展的纵向人口研究之一，该研究长期追踪具有代表性的老年人群样本（与H85、95+及《女性前瞻性人口研究》相关的元数据可在“相关研究”标签下查阅）。 H70是一项基于人群的正常衰老研究，研究对象为70岁人群，同时聚焦医学与认知相关指标。该研究于1971年启动，招募了973名出生于1901-1902年的70岁受试者，研究团队对参与者进行了间歇性追踪，最长追踪时长可达30年。后续研究还纳入了不同出生队列的70岁人群以及75岁人群，所有队列均在不同程度上接受了纵向追踪。H70研究由多个研究团队协同开展，主要涉及老年医学、初级卫生保健、精神病学与流行病学领域。 各项研究的检查流程均尽可能保持统一，以确保不同时间点的研究结果具备可比性。本研究涵盖精神科访谈、体格检查、知情人详细访谈、包含大规模实验室分析的血液样本检测以及心理测评。研究同时收集与社会经济地位、婚姻状况、居住环境、住房条件、受教育程度、宗教信仰、业余爱好及生活事件相关的资料。此外还开展了神经生物学相关检查，包括颅脑与脊髓的计算机断层扫描（computed tomography, CT）、磁共振成像（magnetic resonance imaging, MRI），以及腰椎穿刺与脑脊液分析。研究人员会对哥德堡市内所有主要医院、老年与精神卫生机构及门诊诊所的登记数据进行评估，以识别心理与躯体疾病病例。痴呆、抑郁、精神障碍、睡眠障碍、焦虑障碍及创伤后应激障碍（post-traumatic stress disorder, PTSD）均依据《精神障碍诊断与统计手册第三版修订版（DSM-III-R）》与《精神障碍诊断与统计手册第四版（DSM-IV）》进行诊断。躯体疾病则依据既定标准进行分类。 ## 研究目标 初始研究目标如下： 1. 丰富该年龄组人群正常衰老进程与正常生理状态的相关研究认知 2. 全面调研该人群的社会与医疗健康状况 3. 获取基础数据，用于规划老年照护服务 4. 为受试者提供全面的健康检查 一项针对1944年出生且居住于哥德堡的出生队列的全新H70研究已于2014至2015年间开展。
