[EN] Objective The present study seeks to extend previous bibliometric studies on eating disorders (EDs) by including a time-dependent analysis of the growth and evolution of multi-author collaborations and their correlation with ED publication trends from 1980 to 2014 (35 years). Methods Using standardized practices, we searched Web of Science (WoS) Core Collection (WoSCC) (indexes: Science Citation Index-Expanded [SCIE], & Social Science Citation Index [SSCI]) and Scopus (areas: Health Sciences, Life Sciences, & Social Sciences and Humanities) to identify a large sample of articles related to EDs. We then submitted our sample of articles to bibliometric and graph theory analyses to identify co-authorship and social network patterns. Results We present a large number of detailed findings, including a clear pattern of scientific growth measured as number of publications per five-year period or quinquennium (Q), a tremendous increase in the number of authors attracted by the ED subject, and a very high and steady growth in collaborative work. Conclusions We inferred that the noted publication growth was likely driven by the noted increase in the number of new authors per Q. Social network analyses suggested that collaborations within ED follow patters of interaction that are similar to well established and recognized disciplines, as indicated by the presence of a ¿giant cluster¿, high cluster density, and the replication of the ¿small world¿ phenomenon¿the principle that we are all linked by short chains of acquaintances.

[EN] Eduardo Primo Yúfera was the founder of the Institute of Agrochemicals and Food Technology (IATA-CSIC) and was its director until being appointed president of the Spanish National Research Council. He is considered both patron and promoter of the fields of food science and technology and chemical ecology in Spain, as well as pioneer of the innovation system model (R+D+i). Throughout his long research career,which lasted 65 years, he published 291 scientifi c papers, with an average of 4.48 papers per year. Of these, 89.3 % were in collaboration with others: a total of 161 different coauthors. His efforts to disseminate science led him to create the Revista de Agroquímica y Tecnología de los Alimentos in 1961. A total of 50 % of his scientifi c production was featured in this journal but his work was also published in more than 50 national and international scientifi c journals, of which 36 are included in the Journal Citation Report. Those with the highest impact factors are Journal of Organic Chemistry, Planta and Journal of Agricultural and Food Chemistry, which feature in the fi rst quartile in their respective subject areas. The 86 articles listed in SCI-Expanded have received a total of 482 citations. This study highlights his scientifi c activity, using bibliometric indicators of productivity, collaboration and the scientifi c impact of his publications., [ES]Eduardo Primo Yúfera fue el fundador y director del Instituto de Agroquímica y Tecnología de los Alimentos hasta su nombramiento como presidente del Consejo Superior de Investigaciones Científicas. Es considerado el promotor e impulsor de la Ciencia y Tecnología de los Alimentos y de la Ecología Química en España, así como el precursor del modelo de sistema de innovación (I+D+i). A lo largo de su dilatada trayectoria investigadora, que duró 65 años, publicó 291 artículos científicos, con una media de 4,48 trabajos anuales.

El 50 % de su producción científica quedó recogida en esta revista aunque también publicó en más de 50 revistas científicas nacionales e internaciones, 36 de ellas incluidas en el Journal Citation Report, entre las que destacan por su mayor factor de impacto: Journal of Organic Chemistry, Planta y Journal of Agricultural and Food Chemistry, que se sitúan en el primer cuartil de sus áreas correspondientes. Los 86 artículos del autor que aparecen indexados en el SCI-Expanded han recibido un total 482 citas. Este estudio pone de relieve su actividad científica a través de indicadores bibliométricos de productividad, colaboración e impacto científico de sus publicaciones., [Objetivos] El objetivo de este trabajo es analizar la trayectoria científica de Primo Yúfera mediante indicadores bibliométricos de productividad, colaboración e impacto. Estos indicadores permitirán identificar y caracterizar el papel que jugó en el avance de la ciencia en general y de algunas de sus áreas de conocimiento, como la Farmacognosia, Ciencia y Tecnología de los Alimentos y Ecología Química.
