Vitality attributes and their associations with intrinsic capacity, resilience, and happiness in community-dwelling adults: Results from Gan-Dau Healthy Longevity Plan Wave 2

Our findings demonstrate that low grip strength, suboptimal nutritional status and energy as vitality attributes showed strong link to other IC domains (mainly locomotion and psychological) as well as psychosocial constructs. This finding highlights the heterogeneity of the vitality domain for which it might not be evaluated by a single attribute only but by a combination. Importantly, social factors were strongly associated with vitality impairments, emphasizing the critical role of social determinants in IC assessment.
