“…Thirteen studies (Beard et al., 2019; Beard et al., 2022; Campbell et al., 2022; Lin et al., 2022; Lu et al., 2021; Muneera et al., 2022; Prince et al., 2021; Tang et al., 2023; Yu et al., 2021; Yu et al., 2022b; Yu et al., 2023; Yu, Leung, et al., 2022; Zhao et al., 2021) found a significant association between sex and IC of older adults, with older females being more likely to have poorer IC. However, the other three studies (Jia et al., 2023; Wu et al., 2022; Yu et al., 2022a) did not observe such findings.…”

“…19 of the 29 studies looked at the effect of age on the IC of older adults, involving 95,732 participants. Eighteen studies (Beard et al., 2019; Beard et al., 2022; Campbell et al., 2022; Jia et al., 2023; Leung et al., 2022; Lin et al., 2022; Lu et al., 2021; Ma et al., 2021a; Muneera et al., 2022; Prince et al., 2021; Tang et al., 2023; Wu et al., 2022; Yu et al., 2021; Yu et al., 2022a; Yu et al., 2022b; Yu et al., 2022c; Yu et al., 2023; Zhao et al., 2021) discovered a significant association between age and IC of older adults, indicating that the younger old adults were likely to have a better IC. And only one study (Ma et al., 2021c) showed no differences between age and IC of older adults.…”

“…Ten studies explored an association between marital status and IC among 50,777 participants. Eight studies (Campbell et al., 2022; Lin et al., 2022; Ma et al., 2021a; Muneera et al., 2022; Yu et al., 2022a; Yu et al., 2022b; Yu et al., 2023; Zhao et al., 2021) revealed that older adults with spouses were more likely to have a better IC. However, the other two studies (Jia et al., 2023; Lu et al., 2021) failed to identify the association between marital status and IC of older adults.…”

“…In general, an individual's IC peaks in early adulthood and then gradually decreases as they get older (Beard et al., 2016). IC has been shown to be predictors for adverse health outcomes in older adults, including disability, frailty, hospitalisation, and mortality (Campbell et al., 2022; Tay et al., 2022; Yu et al., 2022a). Maintaining and improving IC can thus help prevent functional impairments and facilitate healthy aging.…”

IntroductionIn 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.AimWe aim to synthesise the factors connected with IC.MethodsThis scoping review followed the five‐stage framework of Arksey and O'Malley and was reported using PRISMA‐ScR guidelines.ResultsIn 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.ConclusionsThis 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 PracticeThe 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 ContributionAs this is a scoping review, no patient or public contributions are required.
