Description
Summary:Introduction In 2015, the term ‘intrinsic capacity’ (IC) was proposed by the World Health Organisation to promote healthy aging. However, the factors associated with IC are still discrepant and uncertain. Aim We aim to synthesise the factors connected with IC. Methods This scoping review followed the five‐stage framework of Arksey and O'Malley and was reported using PRISMA‐ScR guidelines. Results In all, 29 articles were included. IC of older adults is associated with demographic characteristics, socioeconomic factors, disease conditions, behavioural factors, and biomarkers. Age, sex, marital status, occupation status, education, income/wealth, chronic diseases, hypertension, diabetes, disability, smoking status, alcohol consumption, and physical activity were emerged as important factors related to the IC of older adults. Conclusions This review shows that IC is related to multiple factors. Understanding these factors can provide the healthcare personnel with the theoretical basis for intervening and managing IC in older adults. Relevance to Clinical Practice The influencing factors identified in the review help to guide older adults to maintain their own intrinsic capacity, thereby promoting their health and well‐being. The modifiable factors also provide evidence for healthcare personnel to develop targeted intervention strategies to delay IC decline. No Patient or Public Contribution As this is a scoping review, no patient or public contributions are required.
