Older adults' negative beliefs about ageing are related to their health and functioning, but little is known about how perceptions of ageing (POA) relate to frailty status. This study aimed to explore the relationship between POA and frailty. Secondary analysis of data used were from the English Longitudinal Study of Ageing Waves 2 and 5. A POA score was based on participants' responses to 12 statements using a five-point Likert scale at baseline, and a Frailty Index (FI) score was calculated for each participant for both waves. Multiple linear regression models were conducted to assess the relationship between POA and frailty cross-sectionally and longitudinally in models controlled for age, gender, depression symptoms, and socioeconomic status. Older adults with more negative POA had greater frailty (β = .12, p < .001). Negative POA predicted greater frailty 6 years later (β = .03, p < .05). Future work regarding the mechanisms of this relationship is needed to identify ways of intervening to improve health.
老年人对衰老的负面看法与其健康和功能有关，但人们对衰老认知（POA）与虚弱状态的关系知之甚少。本研究旨在探讨 POA 与虚弱之间的关系。使用的数据来自英国老龄化纵向研究波 2 和波 5 的二次分析。在基线时，使用五点李克特量表，根据参与者对 12 个陈述的回答计算 POA 评分，并且针对每个参与者在两个波次计算虚弱指数（FI）评分。在控制年龄、性别、抑郁症状和社会经济地位的模型中，进行了多线性回归模型，以评估 POA 与虚弱之间的横断面和纵向关系。具有更负面 POA 的老年人具有更大的虚弱程度（β=0.12，p<0.001）。负面 POA 预测 6 年后的虚弱程度更大（β=0.03，p<0.05）。需要进一步研究这种关系的机制，以确定改善健康的干预措施。
