Even though ageing is time dependent, there are many factors that influence its development meaning that individual ageing varies significantly among different populations. The first definition of successful ageing proposed that it should include the following three components: low probability of disease and disability, high cognitive and physical capacity, and active participation through social activities (e.g. social relationships, productive activities, education). It has been suggested that a multi-domain approach of successful ageing that incorporates biomedical, social functioning, psychological and lay (subjective) could better predict different health outcomes than a single domain indicator. More recent definitions also incorporate individual’s adaptation to new conditions and capacity of self-management or the syndrome of frailty.
