2012—2022年肌少症营养相关研究的进展及国际热点可视化分析

Progress in nutrition-related research on sarcopenia from 2012 to 2022 and visual analysis of international hotspots

目的研究国内外2012-2022年肌少症营养相关研究的现状、热点以及热点演变趋势。方法检索中国知网(CNKI)和Web of Science(WoS)数据库核心集2012-2022年肌少症营养相关研究文献。运用CiteSpace和wosviewer软件对作者、国家和机构、关键词进行共现分析,对关键词进行聚类分析、时间演化分析、突显词(Burst)分析,同时绘制相应知识图谱。结果CNKI检索共获得484篇文献,包怡红为高产作者,机构发文数最多的是东北林业大学林学院。WoS检索获得2503篇文献,Wakabayashi Hidetaka为高产作者,机构发文频次和中心度最高的分别是Yonsei Univ和Monash Univ,国家发文频次和中心度最高的是美国。国内外的研究热点近年来主要集中在肌少症合并其他疾病营养方面的研究。结论综合推测,未来的研究热点可能集中于肌少症合并其他疾病的临床营养指导研究和相关标准的建立。

Objective To study the current status,hotspots,and evolution trends of nutrition-related research on sarcopenia both domestically and internationally from 2012 to 2022.Methods Research literature on nutrition related to sarcopenia was retrieved in the core sets of China national knowledge infrastructure(CNKI)and Web of Science(WoS)databases,with the retrieval duration from 2012 to 2022.CiteSpace and the wosviewer software were used to conduct co-occurrence analysis on authors,countries,institutions,and keywords.The clustering analysis,time evolution analysis,and Burst analysis were conducted on keywords,and the corresponding knowledge graphs were drawn.Results A total of 484 articles were obtained through CNKI retrieving,with Bao Yihong being a high-yield author and the College of Forestry of Northeast Forestry University having the highest number of published articles.A total of 2503 articles were obtained through WoS retrieving,with Wakabayashi Hidetaka being a high-yield author and the Yonsei Univ and Monash Univ having the highest number of published articles and highest centrality,respectively.In addition,the United States had the highes t number of national publications and centrality.In recent years,research hotspots both domestically and internationally had mainly focused on the nutritional aspects of sarcopenia combined with other diseases.Conclusion Overall,it is speculated that future research hotspots may focus on clinical nutritional guidance research and the establishment of relevant standards for sarcopenia combined with other diseases.
