Abstract：
OBJECTIVE: This longitudinal observational cohort study aimed to clarify the relationship between perceived value (PV) to adopt new behaviors and incident disability in community-dwelling older adults.
METHODS: Participants were 5073 community-dwelling older adults aged ≥65 years in Japan (Mage = 74.0 ± 5.6 years; female = 55.1%). The mean follow-up time was 34.5 months. Baseline data were collected during health checkups in a prospective cohort study. Measurements included engagement in physical activity (PA), cognitive activity (CA), and social activity (SA), PV, health and physical conditions, and demographic characteristics. PV was assessed by asking whether participants thought it was valuable to adopt new behaviors related to PA, CA, and SA. Participants were classified as having higher/lower PV, PA, CA, and SA. Cox proportional hazard models were used to analyze the association between PV and incident disability. PV was examined both as an independent variable and in combination as follows: higher PV and higher PA/CA/SA (high/high); lower PV and higher PA/CA/SA (low/high); higher PV and lower PA/CA/SA (high/low); and lower PV and lower PA/CA/SA (low/low).
RESULTS: Higher PV was significantly associated with a lower hazard ratio (HR) for incident disability. The low/high, high/low, and low/low significantly increased the HR compared to high/high in the analyses of PV & PA and CA. The analysis of PV & SA showed that only low/low increased the HR compared to high/high.
CONCLUSIONS: Having both higher PV and higher activity engagement may contribute to preventing disability development. Both support for activities and value education in older adults may be needed.

摘要：
目的：这项纵向观察性队列研究旨在阐明社区居住老年人采用新行为的感知价值（PV）与意外残疾之间的关系。
方法：参与者是日本5073名年龄≥65岁的社区居住老年人（Mage=74.0±5.6岁；女性=55.1％）。平均随访时间为34.5个月。在一项前瞻性队列研究中，在健康检查期间收集基线数据。测量包括参与体力活动（PA），认知活动（CA），社会活动（SA），PV,健康和身体状况，和人口特征。通过询问参与者是否认为采用与PA相关的新行为有价值来评估PV，CA,SA。参与者被归类为具有较高/较低的PV，PA,CA,SA。Cox比例风险模型用于分析PV与意外残疾之间的关系。将PV作为独立变量并且组合如下进行检查:较高PV和较高PA/CA/SA(高/高);较低PV和较高PA/CA/SA(低/高);较高PV和较低PA/CA/SA(高/低);以及较低PV和较低PA/CA/SA(低/低)。
结果：较高的PV与较低的意外残疾风险比（HR）显著相关。低/高，高/低,在PV&PA和CA的分析中，与高/高相比，低/低显着增加了HR。PV&SA的分析显示,与高/高相比,仅低/低增加HR。
结论：具有更高的PV和更高的活动参与度可能有助于预防残疾发展。可能需要对老年人的活动和价值教育提供支持。
