A Retrospective Literature Review of Eating Disorder Research (1990–2021): Application of Bibliometrics and Topical Trends. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19137710. [PMID: 35805366 PMCID: PMC9265657 DOI: 10.3390/ijerph19137710] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/04/2022] [Revised: 06/17/2022] [Accepted: 06/20/2022] [Indexed: 12/24/2022]
Abstract
Despite the growing importance of eating disorders in society and academic literature, only a few bibliometric review studies using bibliometric analysis were available. Hence, this study aimed to explore and uncover hidden research topics and patterns in articles in terms of eating disorders over the last 30 years. In total, 4111 articles on eating disorders were analyzed using bibliometrics, network analyses, and structural topic modeling as the basis of mixed methods. In addition to general statistics about the journal, several key research topics, such as eating disorder (ED) treatment, ED symptoms, factors triggering ED, family related factors, eating behaviors, and social factors, were found based on topic correlations. This study found the key research variables that are frequently studied with EDs, such as AN, BN, BED, and ARFID. This study may help clinicians comprehend important risk factors associated with EDs. Moreover, the findings about key ED research topics and their association can be helpful for future studies to construct a comprehensive ED research framework. To our knowledge, this is the first study to use topic modeling in an academic journal on EDs and examine the diversity in ED research over 30 years of published research.

Abstract
INTRODUCTION Epidemiologic information on sociodemographic and clinical characteristics in eating disorders in Western European countries are scarce. PURPOSE In this study, we report demographic and clinical characteristics of eating disorder (ED) patients undergoing treatment in five specialized ED centers in Flanders (Belgium). METHOD Data from 642 ED patients were collected by means of a structured questionnaire. RESULTS Data show that 93.8% of patients are female, with an average age of 22.6 years. The largest subgroup in our sample suffers from anorexia nervosa, namely 52.8%. Bulimia nervosa (BN), binge eating disorder (BED) and eating disorder not otherwise specified (EDNOS) account for 17.7%, 10.7% and 18.8% of the sample, respectively. Mean age of onset was 17 years. Mean duration of illness was 5.6 years, but 20.2% of patients had their illness for over 8 years. Anorexia nervosa patients of the restricting type (AN-R) have the shortest duration of illness. BED patients stood out because they were older on average, more often in a relationship and more often in ambulatory treatment. 70% of patients over 20 years old completed higher education, but one-third of this group was unemployed and/or disabled. Remarkably, ED patients grow more up in intact families compared to the general population. CONCLUSIONS Epidemiology of ED patients in treatment in Flanders (Belgium) seems to resemble worldwide findings. The long duration of illness, the common evolution towards chronicity and the early work impairment underline the severe personal and societal impact of ED and call to the need for early detection and treatment of these patients. LEVEL OF EVIDENCE Level V: cross-sectional descriptive study.
