国内外认知衰弱相关研究趋势及热点可视化分析

Visual analysis of research trends and hot topics of cognitive frailty in China and abroad

目的通过文献可视化分析评估国内外认知衰弱相关研究的趋势及热点。方法以"认知衰弱""认知障碍""认知损害""cognitive frailty""cognitive decline""cognitive impairment"等为主题词,检索中国知网、万方、维普、Web of Science数据库收录的认知衰弱领域相关文献,检索时间范围为2013年1月1日至2022年8月31日。基于CiteSpace和VOSviewer可视化软件对相关研究发文量、期刊分布、国家分布及合作、机构分布及合作、研究热点进行网络图谱分析。结果共纳入2500篇文献,其中中文文献151篇,英文文献2349篇,整体发文量呈上升趋势。中文期刊中《中华现代护理杂志》刊载文献数最多(10篇),英文期刊中BMC Geriatr刊载文献数最多(105篇)。英文文献发文量排名前5的国家分别为美国(608篇)、英国(295篇)、意大利(271篇)、中国(252篇)和加拿大(195篇);中文文献发文量排名前5的机构分别为复旦大学(12篇)、首都医科大学(10篇)、郑州大学(7篇)、中南大学(5篇)和华中科技大学(5篇);英文文献发文量最多的机构为日本国家老年服务中心(74篇)。共纳入22个中文关键词,44个英文关键词,网络分析图各节点之间联系紧密,中心化程度非常高;中英文关键词"认知衰弱""老年人""衰弱"均位于核心位置;中文突现词为"认知衰弱""心力衰竭""慢性病"和"风险预测",英文突现词为"cognitive frailty"(认知衰弱)、"questionnaire"(问卷)、"cohort study"(队列研究)、"social isolation"(社会疏离)和"prevention"(预防)。结论认知衰弱领域研究热度逐年攀升,英文发文量整体高于中文,当前主要研究热点为认知衰弱、老年人、衰弱,国内外差异较大。

Objective To evaluate the trend and hotspots of the research on cognitive frailty in China and abroad through literature visualization analysis.Methods Literature related to cognitive frailty were retrieved from the databases of CNKI,Wanfang,VIP and Web of Science from January 1,2013 to August 31,2022 with"cognitive frailty""cognitive decline"and"cognitive impairment"as retrieval terms.Based on the visualization software CiteSpace and VOSviewer,the network map analysis was conducted on the number of publications,journal distribution,country distribution and cooperation,institution distribution and cooperation and research hotspots.Results A total of 2500 literatures were retrieved,including 151 in Chinese and 2349 in English.The number of publications showed an increasing trend with time.Among Chinese journals,Chin J Mod Nurs published the most literature(10 articles),while BMC Geriatr published the most literature(105 articles)in English journals.The top 5 countries in the number of English literature published were the United States(608 articles),the United Kingdom(295 articles),Italy(271 articles),China(252 articles)and Canada(195 articles).The top 5 institutions in the number of Chinese literature published were Fudan University(12 articles),Capital Medical University(10 articles),Zhengzhou University(7 articles),Central South University(5 articles)and Huazhong University of Science and Technology(5 articles).The National Center For Geriatrics Gerontology in Japan published the most English articles(74 articles).A total of 22 Chinese keywords and 44 English keywords were included.The nodes of the network analysis diagram were closely connected and highly centralized.The Chinese and English keywords“cognitive frailty”“elderly”and“frailty”were all in the core position.The Chinese emergent words were“cognitive frailty”“heart failure”“chronic disease”and“risk prediction”.The English burst terms were“cognitive frailty”“questionnaire”“cohort study”“social isolation”and“prevention”.Conclusions The research popularity in the field of cognitive frailty is increasing year by year,and the number of articles published in English is higher than those in Chinese.At present,the main research focus is cognitive frailty,the elderly and frailty with great differences between China and abroad.
