Mapping the landscape and structure of global research on binge eating disorder: Visualization and bibliometric analysis
Publication Type
Original research


Binge-eating disorder (BED) is a clinical syndrome and is considered the most common type of eating disorder. However, our understanding of the global performance and progress of BED research is limited.


To describe and perform a bibliometric analysis of the state of BED research.


The term ‘Binge eating’ was searched in the title throughout the previous year’s up to December 31, 2020. We searched the Scopus and Reference Citation Analysis for publications on Binge eating. The VOSviewer software version 1.6.17 was used to produce the network visualization map of the most frequent author, collaborative relationships between countries/regions, and to determine the hotspots related to binge eating research. In addition, conventional bibliometric indicators were generated.


The search strategy found 2713 total articles and an average of 62 articles per year. Among them, ‘Article’ represented 82.49% of the publications (n = 2238 articles) and was the most frequent type, followed by reviews (n = 243; 8.96%). The number of publications increased steadily during the last decade of the study period. One hundred and thirty-two countries contributed to binge eating research, with 1495 (55.11%) articles published in the United States, followed by Italy with 256 (9.44%), the United Kingdom with 183 (6.75%), and Germany with 182 (6.71%). Currently, the main hot topics related to BED are ‘type of treatment and management and treatment provided to BED”; “processes and pathways to binge eating”; and ‘diagnosis, signs and symptoms, comorbidities and prevalence and associated factors with BED’.


The number of publications has increased noticeably during the previous decade. There are indeed relatively few publications on BED from low-and middle-income nations, so much is to be learned from the experience of all countries. Studies on this topic are critical in all countries to discover risk factors and effective intervention measures. Although our findings are preliminary, they imply that the future prospects for interventions aimed at BED management are bright, focusing on complex models of care and long-term maintenance of therapeutic gains.
