A LITERATURE REVIEW OF HEALTHY AGING TRAJECTORIES THROUGH QUANTITATIVE AND QUALITATIVE STUDIES: A PSYCHO-EPIDEMIOLOGICAL APPROACH ON COMMUNITY-DWELLING OLDER ADULTS

The population of older adults over 60 years is growing faster than any other age group and will more than double between 2020 and 2050. This increase has led to clinical, public health, and policy interest in how to age “successfully”. Before the Rowe and Kahn’s model proposed thirty years ago, aging was seen as a process of losses associated with diseases and disability. However, since the emergence of this model, there has been a shift towards a more positive view, serving for promoting diverse medical or psychosocial models, and personal perspectives. Several technical terms of “success” (e.g. “successful aging”, “healthy aging”, “active aging”, “aging well”…) coexist and compete for the meaning of the concept in the absence of a consensual definition. Our literature review article aims to study discrepancies and similarities between the main technical terms through quantitative or qualitative studies. A literature review using PubMed, SCOPUS, PsycINFO, Psycarticles, Psychology, and Behavioral Sciences Collection, Cochrane database, and clinicaltrials.gov databases was conducted. A total of 1057 articles were found and finally, 43 papers were selected for full extraction. We identified several components in these definitions, which reveal considerable inconsistency. The results particularly suggest that lay personals perspectives could bridge the gap between biomedical and psychosocial models in successful aging. In conclusion, an optimal definition would be a multidimensional one that could combine functional capacities, psychosocial abilities, environmental factors and subjective assessments of one’s own criteria to discriminate older adults at potential risk of “unsuccessful” aging to healthy aging trajectories.
