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.
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 ≥ 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.
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.
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.
欧洲人口老龄化速度正在加快，但尽管人们普遍认识到，有些人比其他人更成功地衰老，但对于成功衰老的公认概念仍然难以捉摸。我们试图在英国人群中建立一种成功衰老的模式，该模式结合了先前提出的成功衰老的主观和客观要素。
结构方程模型用于提供成功衰老的模型，定义为主观和客观方面。数据包括英格兰年龄≥50 岁的 15000 名受试者，他们参加了健康和生活方式调查（HALS）（随访时间>7 年）和英国老龄化纵向研究（ELSA）（随访时间>2 年）。使用 HALS 的 50%随机样本开发模型，并在其他 50%和 ELSA 中进行测试。我们研究了基线时疾病风险、功能和与社会的参与度与随访时的信心和持续参与度之间的关联。
在 HALS 的 50%样本中开发的模型在其他数据集上具有强大的再现性。基线时的低风险和良好功能与随访时的信心和持续参与度相关，基线时的参与度与随访时的参与度独立相关。
该模型提供了关于衰老良好本质的可重复见解，证实了个人弹性和持续参与身体和社会活动的重要性。远非退休，与生活和社会的参与应该是老龄化人口的常态。
