Eating disorders (EDs) are psychiatric disorders that leads to affect the health. In last few decades, EDs have been rising rapidly due to disturbed attitudes towards eating that play a critical role in the maintenance of EDs. This study was performed to assess key bibliometric indicators, visualize the research outcomes in the field, and find the current trends in EDs.

A comprehensive search was conducted utilizing the Web of Science Core Collection (WoSCC) database. The obtained data was imported into Microsoft Excel 2019 and VOSviewer software for windows. The database search was performed for the period from the inception of WoSCC until 2020. The downloaded data was exported into VOSviewer software version 1.6.16 for Windows to construct co-authorship countries, keywords co-occurrence, and journal and organization sources network visualization.

The initial search yielded 16,693 publications, of which 11,322 articles were included in the overall analysis. Furthermore, the top-100 most cited papers were included based on number of citations in descending order. The average citation per year for overall publications (n=11,322) was 830.92 and that of top-100 most cited papers was 490.24. The study authored by Fairburn and Beglin in year 1994 received the highest citations (2,999). Among the top-100 highly cited articles, Fairburn CG was the most prolific author with 10 publications (6,254 citations). The frequently studied research area was psychiatry, and the leading source of publication was Archives of General Psychiatry with 20 published articles and 7,872 citations. The analysis of the overall articles indicted that International Journal of Eating Disorders got 2,500 publications and 88,921 citation score. The University of Minnesota was first in top-100 most cited articles for maximum number of publications (n=12) but from the overall analysis of all the articles, Harvard University was first with a total of 405 publications. The United States of America was the most prominent country with 58 number of documents.

Majority of articles were produced by developed countries. Hence, there is a dire need for interdisciplinary research approaches to evaluate and intervene Eds. We believe that the highly cited articles in feed and EDs may help to some future novel ideas and regulate effective preventive strategies.
