Investigates the relationship between sarcopenia and frailty in older adults, suggesting functional limitations and grip strength play important roles.
Key Points
This research aims to explore how functional limitations mediate the relationship between sarcopenia and frailty, with grip strength moderating this effect.
Analyzed data from 2,885 individuals aged 45 and above from the China Health and Retirement Longitudinal Study.
Utilized Spearman correlation analysis and PROCESS version 3.5 to test mediation and moderation effects.
Sarcopenia was prevalent in 15.9% of the elderly population studied.
Functional limitations mediated 26.23% of the effect of sarcopenia on frailty.
Handgrip strength negatively correlated with sarcopenia, frailty, and functional limitations.
