Developed countries face a fast ageing population and an increase in longevity, two aspects that pose several political, economic, social and health challenges due to the raise of morbidity and disability in later life. In Portugal, individuals aged 80 and older constitute 5.0% (532,219) of the total population (10,562,178) and 26.5% of the population aged 65+ (2,010,064; Brandão, Ribeiro, & Paúl, 2017). Projections for 2080 show a growth by 12.7% points of the oldest old population within the EU-28 (Eurostat, 2019). Specifically for Portugal (Instituto Nacional de Estatística, I.

Trends show that living longer may lead to a long period of disability and frailty with increasing care demands (Alves, Teixeira,
