摘要
目的内在能力(IC)的轨迹可能是非线性和不连续的,传统的线性模型可能无法处理。因此,本研究旨在将 IC 的轨迹模拟为不同 IC 状态之间的转换,并研究其相关因素。方法分析了 60 岁或以上居住在社区的老年人样本(n = 1,588 人)的纵向数据。每年对一组代表不同 IC 领域的 14 个自我报告项目进行管理,以测量四个时间点的 IC 状况。根据受损的 IC 领域(即认知、运动、活力、感觉和心理)的数量,将每个时间点的参与者分为三种 IC 状态之一,即状态 1(0 个受损领域)、状态 2(1-2 个受损领域)和状态 3(3-5 个受损领域)。结果参与者的平均年龄为 75.0 岁,其中 77.4% 为女性。基线时,12.4%的人处于状态 1,51.8%的人处于状态 2,35.8%的人处于状态 3。62.8% 的参与者至少经历过一次状态转换,其中 12% 的参与者每年都经历一次状态转换。这种转换主要发生在相邻的 IC 状态之间,可以来回转换。年龄、性别、婚姻状况、经济充足程度、慢性病数量和自评健康状况是与过渡相关的因素。
Transitions in intrinsic capacity among community-dwelling older people and their associated factors: a multistate modelling analysis
Objectives
Trajectory of intrinsic capacity (IC) can be non-linear and discontinuous, which traditional linear models may not be able to handle. This study thus aimed to model the trajectory of IC as transitions between different IC states and examine their associated factors.
Methods
Longitudinal data from a sample of community-dwelling older people aged 60 years or above (n = 1,588) was analysed. A set of 14 self-reported items representing different domains of IC were administered annually to measure IC at four time points. Based on the number of impaired IC domains (i.e., cognitive, locomotor, vitality, sensory, and psychological), participants at each time point were classified into one of three IC states, namely state 1 (0 impaired domain), state 2 (1–2 impaired domains), and state 3 (3–5 impaired domains). Multistate modelling was used to identify factors associated with the transitions from one state to another.
Results
The mean age of participants was 75.0 years, and 77.4% of them were female. At baseline, 12.4% were in state 1, 51.8% were in state 2, and 35.8% were in state 3. 62.8% of participants experienced at least one transition between states, among which 12% experienced a transition every year. The transitions occurred mostly between adjacent IC states and could take place back and forth. Age, sex, marital status, perceived financial adequacy, number of chronic diseases, and self-rated health were the factors associated with the transitions.
Conclusion
Findings may serve as a valuable reference for guiding future policies to optimize IC and promote healthy ageing using a person-centred approach.
期刊介绍:
There is increasing scientific and clinical interest in the interactions of nutrition and health as part of the aging process. This interest is due to the important role that nutrition plays throughout the life span. This role affects the growth and development of the body during childhood, affects the risk of acute and chronic diseases, the maintenance of physiological processes and the biological process of aging. A major aim of "The Journal of Nutrition, Health & Aging" is to contribute to the improvement of knowledge regarding the relationships between nutrition and the aging process from birth to old age.
