Abstract

Abstract Purpose Investigate the mediating effects of functional fitness on age-related cognitive decline in older adults. Design Cross-sectional study. Methods A sample of 427 community-dwelling older adults reported their medical history and sociodemographic characteristics. Functional fitness was assessed based on the sit-and-reach, grip strength, sit to stand, agility, single-leg stance time and the 6-minute walk tests. Cognitive performance was assessed using the Mini-Mental State Examination. Multilevel mediation models were applied to assess the relationship between age and cognitive status. Results In women, the relationship between age and cognitive decline (β = −0.08; P < 0.05) was attenuated by agility (β = −0.05; P < 0.05) and balance (β = −0.4; P < 0.05). However, none of the functional fitness tests affected the relationship between age and cognitive decline in older men. Conclusion Agility and balance attenuated the relationship between age and cognitive decline among older women by 50% and 40%, respectively.

老年人功能健康与认知:一个中介模型

摘要目的探讨功能适应度对老年人年龄相关认知能力下降的中介作用。设计横断面研究。方法对427名居住在社区的老年人报告其病史和社会人口学特征。功能适应度评估基于坐伸、握力、坐立、敏捷性、单腿站立时间和6分钟步行测试。认知能力评估采用简易精神状态检查。采用多层次中介模型评估年龄与认知状态的关系。结果在女性中，年龄与认知能力下降的关系(β =−0.08;P < 0.05)被敏捷性削弱(β = - 0.05;P < 0.05)和平衡(β = - 0.4;p < 0.05)。然而，没有一项功能健康测试影响年龄和老年男性认知能力下降之间的关系。结论敏捷性和平衡性分别使老年妇女认知能力下降与年龄的关系减弱50%和40%。

期刊介绍： This comprehensive journal is recognized for its useful balance of research and clinical practice articles. For more than twenty five years Physical & Occupational Therapy in Geriatrics has functioned as a forum for allied health professionals as well as others with a focus on rehabilitation of the geriatric client to share information, clinical experience, research, and therapeutic practice. Each issue focuses on current practice and emerging issues in the care of the older client, including rehabilitation and long-term care in institutional and community settings, and innovative programming; the entire range of problems experienced by the elderly; and the current skills needed for working with older clients.
