摘要:
目的：探讨新型冠状病毒肺炎（COVID-19）膳食营养领域研究热点及发展变化。 方法：检索 2019年 12 月 1 日至 2022 年 10 月 5 日科学网（Web of Science）核心集数据库发表的新冠肺炎膳食营养领域（COVID-19-DN）相关文献。采用 CiteSpace、VOSviewer 软件对隶属国家、研究机构、重要期刊、作者耦合、高频关键词等文献内容进行可视化分析。 结果：共纳入 4 665 篇英文文献。文献计量显示，COVID-19-DN 领域相关文献从 2020 年开始几何式上升，2021 年达高峰。国家分布显示，Top3 发文量国家分别是美国（929 篇）、意大利（481 篇）、英国（446篇）。Top3 中介中心性地区为南非（0.17）、苏格兰（0.16）、瑞士（0.14）。研究机构分析显示，发文量及中介中心性均位居 Top10 以上的研究机构计 4 个，分别是牛津大学（Univ Oxford,42 篇）、哈佛医学院（Harvard Med Sch,40 篇）、卡塔尔大学（Qatar Univ, 33 篇）及约翰霍普金斯大学（Johns Hopkins Univ, 33 篇）。其中北京大学（15 篇）是唯一位居Top20 中介中心性的中国研究机构。期刊共被引分析显示，发文量及高被引论文刊出 Top2 期刊是 INT J ENV RES PUB HE（344/18），NUTRIENTS（261/29），位居第三者，前者是 PLOS ONE（74/4），后者是 APPETIE（53/14）。主题词聚类涵盖食品安全、体力活动、营养干预和生活方式四大方面。作者耦合分析显示，Top3 作者分别为意大利作者 elbilali,hamid（12 篇），英国作者 smith,lee 及香港作者 jia,peng（各 10 篇）。高被引论文分析显示，Top15 论文主要来自意大利、英国、美国、西班牙等国家。研究内容涉及不同人群的膳食摄入及行为生活方式变化。尤其关注肥胖青少年、老年共病人群及 ICU 重症病人等新冠易感、高风险群体的营养状态。高频热点关键词包括体力活动、营养、精神健康、肥胖等主要类别。 结论：知识图谱可视化分析能够客观反映 COVID-19-DN 领域研究热点及发展趋势。目前国内外研究者对该领域的研究范式逐渐转向关注单纯营养素之外的以维护健康为中心的支持免疫系统最佳功能的营养模式。
Abstract:
Objective: To explore the research hotspots and development changes in the field of dietary nutritionof coronavirus disease 2019 (COVID-19). Methods: Retrieve the related literature in the field of dietary nutrition of COVID-19(COVID-19-DN) published in the Web of Science core collection from December 1th, 2019 to September 5th,2022. CiteSpace and VOSviewer software was used to visually analyze the content of literature belonging to countries,institutions, important journals, author coupling and high-frequency keywords. Results: A total of 4665 Englishliteratures were included. In terms of literature volume, the literature related to COVID-19-DN had risen geometricallysince 2020 and peaked in 2021. Regarding countries, the top 3 countries with the largest number of articles were theUnited States (n = 929), Italy (n = 481) and the United Kingdom(n = 446) respectively. Top 3 betweeness centralityregions were South Africa (0.17), Scotland (0.16) and Switzerland (0.14). Concerning institutions, there were 4institutions with the number of papers and the Betweeness Centrality ranking above the top 10, including OxfordUniversity (n = 42), Harvard Med Sch (n = 40), Qatar Univ (n = 33) and Johns Hopkins Univ (n = 33). Peking University(n = 15) was the only Chinese institution ranked among Top 20 Betweeness Centrality. In terms of journal co-citation ,the top 2 journals with publications and highly cited papers were "International Journal of Environmental Research andPublic Health" (344/18) and "Nutrients" (261/29). The third place, the former was PLOS ONE (74/4) and the latter wasAPPETIE (53/14). The topic headings cover four major areas: food safety, physical activity, nutritional interventions andlifestyle. In terms of author-coupling, the top 3 authors are Italian author el bilali , hamid (n = 12 ), British author Smith,Lee and Hong Kong author Jia,Peng (n = 10 each). In terms of highly cited papers, the top 15 papers were mainly fromItaly, UK, USA, Spain and other countries. The study covered dietary intake and behavioral lifestyle changes in differentpopulations. Particular attention was paid to the nutritional status of high-risk groups such as obese adolescents, elderlypeople with multiple comorbidities, and ICU critically ill patients. High-frequency hot keywords mainly includedphysical activity, nutrition, mental health, obesity, etc. Conclusion: The visual analysis of knowledge graph couldobjectively reflect the hot spots and development trends in the field of COVID-19-DN research. Currently, both domesticand foreign researchers in this field have gradually shifted their research paradigm to focus on the nutritional model thatsupports optimal immune system function, centered on maintaining health, rather than just considering simple nutrients.
