背景资料：欧洲人口正在迅速老龄化，尽管人们普遍认识到，有些人比其他人更成功地老龄化，但成功老龄化的商定概念仍然难以捉摸。我们试图在英国人口中建立一个成功老龄化的模式，它结合了以前提出的成功老龄化的主观和客观因素。方法：结构方程模型被用来提供一个模型的成功老龄化，在主观和客观方面的定义。数据包括15000名年龄在50岁以上的英国受试者，被招募到健康和生活方式调查（HALS）（随访> 7年）和英国老龄化纵向调查（艾尔莎）（随访> 2年）。使用来自HALS的50%随机样品开发模型，并在其他50%和艾尔莎中进行测试。我们检查了基线时疾病风险、功能和社会参与与随访时的信心和持续参与之间的关系。结果：在50%的HALS样本中建立的模型在其他数据集中具有很强的可重复性。基线时的低风险和良好功能与随访时的信心和持续参与相关，基线时的参与与随访时的参与独立相关。结论：这个模型提供了关于衰老本质的可重复的见解，证实了个人弹性和持续参与身体和社会活动的重要性。参与生活和社会应该成为老龄人口的常态，而不是退休。
Background: European populations are ageing rapidly yet, although, it is widely recognized that some individuals age more successfully than others, an agreed concept of successful ageing remains elusive. We sought to develop a model of successful ageing in a British population, which combines the subjective and objective elements of successful ageing that have previously been proposed. Methods: Structural equation modelling was used to provide a model of successful ageing, defined in subjective and objective terms. The data comprised 15 000 subjects aged epsilon 50 years in England, recruited to the Health and Lifestyle Surveys (HALS) (followed up > 7 years) and the English Longitudinal Survey of Ageing (ELSA) (followed up > 2 years). A model was developed using a 50% random sample from HALS and tested in the other 50% and in ELSA. We examined the association of risk of disease, functioning and engagement with society at baseline with confidence and continued engagement at follow-up. Results: The model developed in the 50% sample of HALS was strong and reproducible in the other data sets. Low risk and good function at baseline are associated with confidence and continued engagement at follow-up, with engagement at baseline independently associated with engagement at follow-up. Conclusions: This model provides reproducible insights on the nature of ageing well, confirming the importance of personal resilience and continued involvement in physical and social activities. Far from retiring, engagement with life and society should be the norm for ageing populations.
