英国老龄化纵向研究（艾尔莎）是一项对生活在英格兰的550岁男性和女性的代表性队列进行的小组研究。该研究是美国健康和退休研究的姊妹研究，具有多学科方向，涉及收集经济、社会、心理、认知、健康、生物和遗传数据。该研究于2002年开始，每两年对样本进行一次随访。使用计算机辅助个人访谈和自我完成问卷收集数据，每4年额外进行一次护士访视以评估生物标志物。最初的样本包括11391名成员，年龄从50岁到100岁不等。艾尔莎与其他国家的老龄化研究协调一致，以便于进行国际比较，并与财务和卫生登记数据挂钩。数据集在收集后不久就向研究人员和分析人员公开提供（www.esds.ac.uk/longitudinal/ access/elsa/l5050.asp）。
The English Longitudinal Study of Ageing (ELSA) is a panel study of a representative cohort of men and women living in England aged 550 years. It was designed as a sister study to the Health and Retirement Study in the USA and is multidisciplinary in orientation, involving the collection of economic, social, psychological, cognitive, health, biological and genetic data. The study commenced in 2002, and the sample has been followed up every 2 years. Data are collected using computer-assisted personal interviews and self-completion questionnaires, with additional nurse visits for the assessment of biomarkers every 4 years. The original sample consisted of 11 391 members ranging in age from 50 to 100 years. ELSA is harmonized with ageing studies in other countries to facilitate international comparisons, and is linked to financial and health registry data. The data set is openly available to researchers and analysts soon after collection (http://www.esds.ac.uk/longitudinal/ access/elsa/l5050.asp).
