年龄相关变化意识的概念涵盖了人们对自己在包括健康在内的多个生活领域中所经历的积极（AARC-增益）和消极（AARC-损失）的年龄相关变化的感知。我们研究了身体和心理健康状况的数量和类型与AARC-增益和AARC-损失之间的横断面关联。样本包括参与英国PROTECT研究的3,786名中年和老年成人（平均年龄为67.04岁，标准差为6.88）。我们使用层次回归模型分析了在包括社会人口学变量（模型1）后，身体健康状况的数量（模型2）和心理健康状况的数量（模型3）是否解释了AARC-增益和AARC-损失中显著额外的方差，并且物质数量与AARC之间的关联是否取决于参与者的年龄。我们使用多元回归模型分析了身体和心理健康状况的类型与AARC-增益和AARC-损失之间的关联。较多的身体健康状况与较高的AARC-增益和较高的AARC-损失相关，但该关联并不取决于参与者的年龄。在控制了身体健康状况数量后，较多的心理健康状况与较高的AARC-损失相关，但与AARC-增益无关，且该关联在年龄较大的参与者中更为显著。较大的AARC-增益与目前患有癌症，较大的AARC-损失与轻度认知障碍，帕金森病，关节炎，完全缓解的癌症，骨质疏松，抑郁症，焦虑症和人格障碍的诊断之间存在较小的影响。其余健康状况要么与AARC-损失关系微不足道，要么在统计上无关。中年和老年成人患有更多的身体健康状况和心理健康状况可能更容易对自己的衰老持消极观点。然而，特定的身体健康状况，如关节炎，以及特定的心理健康状况，如抑郁症，可能使成年人特别容易对年龄相关观念持消极态度。版权所有 © 2023 Sabatini, Turner, Brooker, Ballard, Corbett and Hampshire.

The concept of Awareness of Age-Related Changes captures people's perceptions of the positive (AARC-gains) and negative (AARC-losses) age-related changes they experience in several life domains, including their health. We investigated the cross-sectional associations of number and type of physical and mental health conditions with AARC-gains and AARC-losses.The sample comprised 3,786 middle-aged and older adults (mean age = 67.04 years; SD = 6.88) participating to the UK PROTECT study. We used hierarchical regression models to analyze whether after having included sociodemographic variables (model 1), number of physical (model 2) and of mental (model 3) health conditions explained a significant additional amount of variance in AARC-gains and AARC-losses, and whether the association between number of conditions and AARC depended on participants' age. We used multiple regression models to analyze the associations of types of physical and mental health conditions with AARC-gains and AARC-losses.A higher number of physical health conditions was associated with higher AARC-gains and higher AARC-losses, but the association did not depend on participant age. After controlling for the number of physical health conditions, a higher number of mental health conditions was associated with higher AARC-losses but not with AARC-gains, and the association was stronger among older participants. Small effects were found between greater AARC-gains and current cancer and between greater AARC-losses and diagnoses of mild cognitive impairment, Parkinson's disease, arthritic condition, cancer in full remission, osteoporosis, depression, anxiety disorders, and personality disorder. The remaining health conditions were either negligibly or non-statistically related to AARC-losses.Middle-aged and older adults having more physical health conditions and more mental health conditions may be at higher risk of negative views on their own aging. However, specific physical health conditions, such as arthritis, and certain mental health conditions, such as depression, may make adults particularly vulnerable to negative age-related perceptions.Copyright © 2023 Sabatini, Turner, Brooker, Ballard, Corbett and Hampshire.
