Global Trends in Vitamin D Deficiency Research during 2014 to 2023

A Scientometric Exploration on Contributors, Leading Nations and Key Collaborations

Abstract

This study aims to analyze global research trends on vitamin D deficiency from 2014 to 2023. A scientometric approach is applied to analyze 28,916 documents indexed in the Scopus database. Bibliographic data of the documents were extracted in CSV format and analyzed using MS Excel 2021 and VOSviewer. The analysis found 2021 to be the most productive year, and the majority were journal articles (70%). The primary language used for publication is English, accounting for 93.53%, with the United States leading in publication output, followed by China, the UK, Italy, and India. Medicine, among subjects, contributed the largest publication share of 53%, followed by "Biochemistry, Genetics, and Molecular Biology" (13%). "Harvard Medical School" was the most dominant institution, with the highest number of contributions in this field. This research has identified leading journals, key contributors, and their collaboration networks, providing valuable insights that can guide future studies, foster collaborative research, and optimise funding allocation by various agencies in the field of vitamin D deficiency.
