身体活动与老年人认知领域研究热点与主题演变

Physical activity and cognition in older adults:research hotspot and topic evolution

背景:近年来,身体活动与老年人认知领域方面的研究激增,并且该领域的研究热点和研究主题在不断演变。然而,目前缺乏对该领域文献的全面梳理。目的:通过文献计量学方法,探究当前身体活动与老年人认知领域的国际研究热点与内容。方法:作者对Web of Science核心合集数据库进行检索,检索数据库包括:SCI-EXPANDED,SSCI,A&HCI,CPCI-S,CPCI-SSH,BKCI-S,BKCISSH,ESCI,CCR-EXPANDED,IC等,检索语言为英文。以Web of Science数据库中所收录的2593篇相关文献为内容,利用CiteSpace软件进行可视化分析。结果与结论:身体活动与老年人认知领域的主题演变包括5个阶段:老年人陪伴机器人的研究、痴呆等疾病风险的研究、认知能力及其相关能力的研究、身体活动水平与老年人认知功能关系的研究以及不同干预方式及其机制的研究。该领域的研究趋于多元化,在疾病、认知降低风险研究的基础上,更注重不同身体活动方式对认知的影响以及相关机制的研究,这是当前的研究热点也将是以后主要的研究趋势。

BACKGROUND:In recent years,there has been an explosion of research in the field of physical activity and cognition of older adults,and the research hotspots and topics in this field are constantly evolving.However,a comprehensive review of the literature in this field is lacking.OBJECTIVE:To explore the current international research hotspots and contents in the field of physical activity and cognition of older adults using bibliometrics.METHODS:The Web of Science Core Collection Database,including SCI-EXPANDED,SSCI,A&HCI,CPCI-S,CPCI-SSH,BKCI-S,BKCI-SSH,ESCI,CCR-EXPANDED,IC,etc.,was searched for relevant literature in English.CiteSpace software was used to visualize and analyze 2593 documents collected in the Web of Science database.RESULTS AND CONCLUSION:The evolution of the topics of physical activity and cognition of older adults includes five stages:research on companion robots for older adults,research on the risk of diseases such as dementia,research on cognitive ability and its related ability,research on the relationship between physical activity level and cognitive ability in older adults,and research on different intervention methods and their mechanisms.The research in this field tends to be diversified.On the basis of the research on diseases and cognitive risk reduction,more attention has been paid to the effects of different physical activity modalities on cognition and the related mechanisms, which is the current research hotspot and will be the main research trend in the future.
