Global Research Trends and Future Directions in Selenium's Role in Child Development: A Bibliometric Analysis

Aim: Selenium is an essential trace element for the human body, which significantly affects the growth and development of children. This study aimed to investigate the effects of selenium on child development, analyze emerging concepts, and predict future trends. Material and Methods: Using comprehensive search strategies in the Scopus and Web of Science Core Collection databases, 155 articles in English were identified. Publications, citations, prominent authors, collaboration networks, and influential journals were analyzed using the tools Biblioshiny and Bibliometrics R. Results: A steady growth trajectory was shown, with publications and research findings over the past 51 years demonstrating an increasing awareness of the positive effects of selenium on child development and growth. The United States and China were identified as the leading contributors. Peking University, Charité - Universitätsmedizin Berlin, and Humboldt University were the leading institutions, with Skalny A. and Chen J. identified as the most prolific authors. Biological Trace Element Research has emerged as the leading journal for disseminating knowledge in this field. In addition, keyword analysis revealed the importance of terms such as “selenium,” “human,” and “child.” Overall, this comprehensive study, the product of a global collaboration on selenium and its relationship to child growth, provides an in-depth study of selenium. Conclusion: The results of this analysis highlight future research priorities and the need for continued research in this area, advocating for expanded interdisciplinary studies to further explore the mechanisms and broader effects of selenium on child development and health.
