A bibliometric analysis of neurobiological and behavioral disturbances of cafeteria diet interventions

Abstract

Obesity is a global epidemic mainly caused by the overconsumption of western diets, high in fat and sugars. Cafeteria diet administered to rodents is an effective model of the metabolic, neurobiological, and behavioral disturbances caused by the over consumption of western diet in humans. However, this is still an emerging research field. To provide information about the past, present and future of the research field, this study aims to explore the research field of cafeteria diet and behavior through bibliometric analysis. Original articles on cafeteria diet and behavior were obtained from Pubmed, Scopus and Web of Science databases from 2013 to Octuber 30, 2023. The R packages litsearchr, bibliometrix, sjrdata and mblm were used for descriptive and inferential statistics. Linear regression, concept mapping and trend analysis were used for relationship analysis. 85 articles included from 457 authors, 20 countries and 56 institutions were included. 46 from Pubmed, 12 from Scopus and 27 from Web of Science. The 25 topmost productive authors were from Spain, Brazil, Australia, Switzerland, and USA. 15 authors had an h-index higher than 3. The institution with the largest production of articles is the University of South Wales with 10 articles. A simple linear regression could not establish significance between the relationship between the impact factor and the number of citations received. In addition, a conceptual structure map was performed, and 5 clusters were found. Finally, by a bi-factor analysis, a trend topic established that anxiety is the term currently in trend and since 2017 in the cafeteria diet and behavior research field. The present study explores the performance of authors, countries, institutions, and journals on classical measures of scientific parameters. This helped to model multiple correspondence and trend analyses that provide a reliable source of information to direct research on cafeteria diet interventions.
