Obesity is a key public health problem. The advancement of gut microbiota research sheds new light on this field. This article aims to present the research trends in global intestinal microbiota studies within the domain of obesity research.
Bibliographic information of the publications on intestinal microbiota and obesity was retrieved from the Scopus database, and then analyzed by using bibliometric approaches.
A total of 3,446 references were retrieved; the data indicated a steady growth and an exponential increase in publication numbers. The references were written in 23 different languages (93.8% in English). A number of 3,056 English journal papers were included in the further analyses. Among the 940 journals, the most prolific ones were , and . North America and Europe were the highest publication output areas. The US (995 publications) ranked first in the number of publications, followed by the China (243 publications) and France (242 publications). The publication numbers were significantly correlated with gross domestic product (GDP), human development index (HDI), and population number (PN). International collaboration analysis also shows that most of the collaborations are among developed countries.
This comprehensive bibliometric study indicates that gut microbiota is a significant topic in the obesity research. The structured information may be helpful in understanding research trends, and locating research hot spots and gaps in this domain.
肥胖是一个关键的公共卫生问题。肠道微生物群研究的进展为该领域带来了新的启示。本文旨在呈现肥胖研究领域内全球肠道微生物群研究的趋势。
从Scopus数据库中检索有关肠道微生物群与肥胖的出版物的文献信息，然后采用文献计量学方法进行分析。
共检索到3446条参考文献；数据显示出版物数量呈稳步增长且呈指数级上升。参考文献用23种不同语言撰写（93.8%为英文）。进一步分析纳入了3056篇英文期刊论文。在940种期刊中，发文量最多的是《 》《 》和《 》。北美和欧洲是出版物产出最高的地区。美国（995篇出版物）在出版物数量上排名第一，其次是中国（243篇出版物）和法国（242篇出版物）。出版物数量与国内生产总值（GDP）、人类发展指数（HDI）和人口数量（PN）显著相关。国际合作分析还表明，大多数合作发生在发达国家之间。
这项全面的文献计量学研究表明，肠道微生物群是肥胖研究中的一个重要课题。这些结构化信息可能有助于了解研究趋势，以及定位该领域的研究热点和空白。
