Promoting healthy ageing through measures addressing social determinants of older adults' health: A scoping review protocol

Abstract

Introduction The global population is ageing with percentages of older adult individuals aged 65 years and older projected to increase from 17% in 2020 to 22% in 2040. Therefore, comprehensive approaches that integrate health and social care are increasingly vital to address the needs of the older population and promote healthy ageing. The WHO defines healthy ageing as maintaining functional ability and well-being in later life, emphasising holistic health beyond disease absence. Older adults' health outcomes are influenced by social determinants of health (SDH) encompassing factors across various domains including healthcare access, education access, social and community context, neighbourhood and built environments and economic stability. Research on healthy ageing is mainly focused on healthcare achievements, but designing comprehensive measures requires attention to the full spectrum of SDH. This protocol describes the scoping review that aims to collate and critically appraise published articles on SDH measures in older adults to promote healthy ageing. Methods and analysis The scoping review will follow Arksey-O'Malley five-stage scoping review method and the Joanna Briggs Institute's Scoping Review Methods Manual. Studies available in English-language published from 1 January 2015, the year the WHO's first World Report on Ageing and Health was published, and up to 1 February 2025, will be identified from databases including PubMed, Scopus, CINAHL and Cochrane Database for Systematic Reviews. Two reviewers will screen titles and abstracts, followed by independent full-text screenings for inclusion. After data extraction, a narrative synthesis will be performed. Experts in the field will be consulted to ensure the results' feasibility and relevance. Ethics and dissemination Ethical approval is not required for this review since it relies on available data. The results of the review will be disseminated through publication in journals and presentations at local, regional and global healthy ageing conferences or any related conferences.
