Global research in sarcopenia: High-cited papers, research institutions, funding agencies and collaborations, 1993-2022.

Background And Aims: This bibliometric analysis aims to analyze the high-cited papers (HCPs), those which have received >100 citations) on Sarcopenia to provide insight into publication performances and research characteristics of the literature.

Methods: Global HCPs on Sarcopenia research were identified from the Scopus database from January 1993 to August 2022. VOSviewer, and Biblioshiny software were used to visualize the collaborative interaction among most productive countries, organizations, authors, and keywords. Select bibliometric measures were applied to evaluate the publication productivity and their influence in this area.

Results: Out of 6219 publications on Sarcopenia only 398 were HCPs. These HCPs received an average of 271.7 citations per publication (CPP). The most productive organizations were the Università Cattolica del Sacro Cuore, Italy, and Jean Mayer USDA Human Nutrition Center on Aging, USA. The most impactful organizations in terms of CPP and relative citation index were CHU de Toulouse, France, and Università Cattolica del Sacro Cuore, Italy. The most productive authors were Landi F and Morley JE, and Anker SD from Italy and Germany respectively. The most impactful authors were: Cederholm T (Sweden), Cruz JAJ (Spain) and Rolland Y (France). There were few/no HCPs from South America, Africa, South Asia, and USSR.

Conclusion: Sarcopenia research has been predominantly done in USA, Europe, and China, and rarely from low and middle-income countries. Further focus of research should be on its etiopathogenesis (especially at the molecular level), prevalence in different communities, methods to diagnose it in early stages, and its cost-effective management.
