BACKGROUND
Coronavirus disease 2019 (COVID-19) has had a significant influence on nutritional status. There have been several studies on dietary habits and nutritional status in connection with COVID-19. However, there has been no research on the bibliometric analysis of these papers. Therefore, our objective was to assess the most relevant scientific research on nutrition and COVID-19, as well as to assess current hot themes.
METHODS
We obtained data from the Scopus database on June 30, 2021. Qualitative and quantitative analyzes were conducted based on the Scopus. Collaboration and term analysis was performed using VOSviewer software version 1.6.16.
RESULTS
At the time of data collection, there were 177,946 documents in COVID-19. Scopus found 1885 articles related to nutrition and COVID-19 after narrowing the search to those terms. This includes 1309 (69.44%) research articles, 268 (14.22%) review papers, and 308 other types of document. The USA was the largest producer, with 24.83% of the documents, followed by Italy with 11.88% (n = 224), the UK with 10.82% (n = 204), and China with 7.59% (n = 143). The most active institution was Sapienza Università di Roma (n = 30, 1.59%). The leading journal in COVID-19 nutrition research was Nutrients (n = 115, 6.10%). The article with 310 citations published by Di Renzo et al. in 2020 was the most influential reference. The hot topics were stratified into three clusters: (1) "Food security in the COVID-19 pandemic"; (2) "nutritional determinants and COVID-19 outcomes"; and (3) "changes in dietary habits during the COVID-19 pandemic and its consequences".
CONCLUSIONS
This is the first bibliometric research to offer comprehensive information on COVID-19 and nutrition in the published literature. Research will likely be helpful to scholars and policymakers. This study sheds light on the growth and development of nutrition and covid-19-related research and should contribute to the expansion of the global frontier in the major hot topics, including "food security in the COVID-19 pandemic"; "nutritional determinants and COVID-19 outcomes"; and "changes in diet habits during the COVID-19 pandemic and its consequences".
背景
2019 年冠状病毒病（COVID-19）对营养状况有重大影响。已经有几项关于与 COVID-19 相关的饮食习惯和营养状况的研究。然而，对于这些论文的文献计量分析还没有研究。因此，我们的目标是评估与营养和 COVID-19 相关的最相关科学研究，并评估当前的热门主题。
方法
我们于 2021 年 6 月 30 日从 Scopus 数据库中获取数据。根据 Scopus 进行定性和定量分析。使用 Vosviewer 软件版本 1.6.16 进行合作和术语分析。
结果
在数据收集时，COVID-19 有 177946 篇文献。缩小搜索范围后，Scopus 在搜索到 1885 篇与营养和 COVID-19 相关的文章。其中包括 1309 篇（69.44%）研究文章、268 篇（14.22%）综述文章和 308 篇其他类型的文献。美国是最大的生产者，占文件的 24.83%，其次是意大利（11.88%，n=224）、英国（10.82%，n=204）和中国（7.59%，n=143）。最活跃的机构是罗马 Sapienza 大学（n=30，1.59%）。在 COVID-19 营养研究中，领先的期刊是《营养素》（n=115，6.10%）。Di Renzo 等人于 2020 年发表的一篇被引 310 次的文章是最有影响力的参考文献。热门话题分为三个层次：（1）“COVID-19 大流行中的粮食安全”；（2）“营养决定因素和 COVID-19 结果”；（3）“COVID-19 大流行期间饮食习惯的变化及其后果”。
结论
这是第一份关于 COVID-19 和营养在已发表文献中的综合信息的文献计量研究。研究结果可能对学者和政策制定者有帮助。本研究揭示了营养与 COVID-19 相关研究的增长和发展，应该有助于扩大全球在主要热门话题中的前沿领域，包括“COVID-19 大流行中的粮食安全”；“营养决定因素和 COVID-19 结果”；以及“COVID-19 大流行期间饮食习惯的变化及其后果”。
