Publication Trends for Sarcopenia in the World: A 20-Year Bibliometric Analysis.

BACKGROUND

Sarcopenia, an age-related degenerative disease, seriously affects the health and quality of life of the elder. The research of sarcopenia has changed dramatically around the world. This article aims to analyze global trends in this field over the past 20 years.

METHODS

"Sarcopenia" was used as the search term to retrieve relevant publications from the WOS and PubMed databases. Co-occurrence, literature coupling, co-citation, and co-author analysis were performed by using the software VOS viewer. We analyzed the trends of sarcopenia research over the last 20 years from different aspects, such as the number of papers, total citations, average citations per item, h-index, research area, article types, institutions, country, journals, and funding.

RESULTS

We retrieved 13,421 research articles published on sarcopenia between 2001 and 2020. The results showed that the USA made the highest contributions to this field. Geriatrics gerontology is the most study classification of sarcopenia. Basic research on sarcopenia in geriatric gerontology accounts for approximately 16.496% of global publications. The Osteoporosis International published the largest number of sarcopenia-related studies. The United States Department of Health Human Services was the leading funding organization, which sponsored 1,604 articles.

CONCLUSION

Global sarcopenia research increased rapidly from 2001 to 2020, especially recently. The research leader of sarcopenia is the USA. In the future, the study of sarcopenia will continue to focus on aging, nutrition, and exercise and will delve deeper into molecular mechanisms. On the other hand, revealing the link between sarcopenia and other diseases will be the next research hotspot.
