研究目的：韩国国家健康保险服务（NHIS）老年人队列研究是一个韩国全国性的回顾性管理数据队列研究，旨在提供高质量的纵向数据，用于探索老年人社会经济和健康状况变化的各个方面，预测风险因素并调查其健康结果。在2002年由60岁及以上的老年人组成。它由558 147人组成，通过10%简单随机抽样方法从国家健康信息数据库中的550万名60岁以上的受试者中选出。该队列随访至2015年的所有科目，除了那些谁是dead.Findings到目前为止的医疗保健利用率和入院率是最高的急性上呼吸道感染和流感（75.2%）。10年（至2012年）的年龄标准化（参照世界标准人口定义）死亡率为4333/100000人-年。恶性肿瘤是男女最常见的死亡原因（男性为1032.1/100 000人年，女性为376.7/100 000人年）。2008年申请长期护理服务的人数为34，483人，其中17.9%的人被评定为1级，即完全依赖他人的帮助生活。今后的计划根据《韩国公共数据的提供和利用促进法》，为政策和学术研究提供数据。NHIS-Senior队列数据目前仅提供给韩国研究人员，但国外研究人员可以通过与韩国研究人员进行联合研究来获得数据。该队列将由NHIS维护并持续更新。
Purpose The National Health Insurance Service (NHIS)Senior was set up to provide high-quality longitudinal data that can be used to explore various aspects of changes in the socio-economical and health status of older adults, to predict risk factors and to investigate their health outcomes.Participants The NHIS-Senior cohort, a Korean nationwide retrospective administrative data cohort, is composed of older adults aged 60 years and over in 2002. It consists of 558 147 people selected by 10% simple random sampling method from a total of 5.5 million subjects aged 60+ in the National Health Information Database. The cohort was followed up through 2015 for all subjects, except for those who were deceased.Findings to date The healthcare utilisation and admission rates were the highest for acute upper respiratory infections and influenza (75.2%). The age-standardised (defined with reference to the world standard population) mortality rate for 10 years (through 2012) was 4333 per 100 000 person-years. Malignant neoplasms were the most common cause of death in both sexes (1032.1 per 100 000 person-years for men, 376.7 per 100 000 person-years for women). A total of 34 483 individuals applied for long-term care service in 2008, of whom 17.9% were assessed as grade 1, meaning that they were completely dependent on the help of another person to live daily life.Future plans The data are provided for the purposes of policy and academic research under the Act on Promotion of the Provision and Use of Public Data in Korea. The NHIS-Senior cohort data are only available for Korean researchers at the moment, but it is possible for researchers outside the country to gain access to the data by conducting a joint study with a Korean researcher. The cohort will be maintained and continuously updated by the NHIS.
