Abstract:
Objective:To explore the latent classes of intrinsic capacity and their influencing factors among hospitalized older adults, providing a basis for developing targeted intervention strategies.Methods:A convenience sampling method was used to recruit 371 hospitalized older adults from Beijing Hospital between April 2022 and July 2023. The integrated care for older people comprehensive assessment tool was used to assess the intrinsic capacity of hospitalizd older adults, along with grip strength tests. Latent class analysis (LCA) was employed to classify the intrinsic capacity of hospitalizd older adults, and multinomial Logistic regression analysis was conducted to explore the influencing factors of different latent classes.Results:Among the 371 older adults, 78.98% (293/371) exhibited declines in various dimensions of intrinsic capacity, with impairment detection rates of 36.39% (135/371) in cognition, 34.23% (127/371) in mobility, 21.02% (78/371) in vitality, 33.69% (125/371) in psychological well-being, and 47.98% (178/371) in sensory function. The LCA results identified three latent classes of intrinsic capacity: high mobility-moderate sensory group (39.08%, 145/371) , low cognition-high mobility group (26.68%, 99/371) , and low mobility group (34.23%, 127/371) . Multinomial Logistic regression analysis revealed that age, gender, monthly family income, polypharmacy, and grip strength were influencing factors of the latent classes of intrinsic capacity ( P<0.05) . Conclusions:The intrinsic capacity of hospitalized older adults is heterogeneous. It is essential to promptly identify the characteristics of intrinsic capacity in different groups, with particular attention to older adults in the low cognition-high mobility group and low mobility group, and implement targeted interventions to prevent and improve adverse outcomes.
