Abstract:
Objective:To investigate the current status and trajectory of intrinsic capacity in community-dwelling older adults and to analyze its influencing factors.Methods:A longitudinal study was conducted from September 2022 to March 2024. A total of 360 older adults were selected by convenience sampling from the Desheng community, Xicheng District of Beijing City and Liucun Community of Xingtai City, Hebei Province. The Intrinsic Capacity Assessment Scale and the Influencing Factors Questionnaire were administered at three-time points: baseline (T1), 6 months (T2), and 12 months (T3). Binary Logistic regression analysis revealed that age, grip strength, the number of geriatric syndromes, and types of social activities were significant influencing factors of intrinsic capacity trajectories in community-dwelling older adults ( P<0.05) . Results:A total of 360 participants were assessed at T1, with 58 and 30 lost to follow-up at T2 and T3, development respectively. Ultimately, 272 older adults completed the follow-up. The growth mixture modeling identified two trajectory types: a high-score stable group (92.3%, 251/272) and a low-score declining group (7.7%, 21/272). Binary Logistic regression analysis showed that age, grip strength, number of geriatric syndromes, and types of social activities were influencing factors of intrinsic capacity trajectories in community-dwelling older adults ( P<0.05) . Conclusions:Intrinsic capacity development trajectories in community-dwelling older adults are heterogeneous. Healthcare professionals should focus on older adults with advanced age, lower grip strength, more geriatric syndromes, and fewer types of social activities to assess and manage their intrinsic capacity and formulate targeted interventions at an early stage.
