Abstract

Background: The aim of this study was to conduct a bibliometric analysis of published studies on the relationship between inflammatory bowel disease (IBD) and depression. The study also aims to identify the major researchers, institutions, and countries and regions in this field to identify current research hotspots.

Methods: The Web of Science Core Database in the Science Citation Index Expanded database was selected as the data source and was searched to obtain relevant literature on IBD and depression. Bibliometric analysis of relevant publications was performed by utilizing VOSviewer, CiteSpace, bibliometrix, and Microsoft Excel 2019.

Results: A total of 393 papers were included from January 1, 2014, to December 25, 2023, showing a general upward trend in the number of publications. There were 48 countries and 743 institutions, of which the United States had the largest number of publications. There were 2250 authors involved in research in the field, with clear collaborations between authors. There were currently 163 journals that have published research on this topic, with IBDs being the most cited journal. IBD and depression-related studies are gradually gaining attention from researchers, and the research direction is gradually expanding to epidemiology, gut microbiota, and other related topics.

Conclusion: This study comprehensively summarizes the research trends and developments of IBD and depression through bibliometrics. This information points out the research frontiers and hot directions in recent years, which will serve as a reference for researchers in this field.
