A bibliometric analysis of global research on vitamin D and reproductive health between 2012 and 2021: Learning from the past, planning for the future

Abstract

BackgroundVitamin D plays an invaluable role in reproductive health, but vitamin D insufficiency and deficiency are generally common among couples of childbearing age and pregnant women. This study aimed to evaluate the evolution, development trend, and research hotspot of publications on vitamin D and reproductive health.MethodsThe literature on vitamin D and reproductive health between 2012 and 2021 was retrieved from the Web of Science Core Collection (WoSCC). We used VOSviewer and CiteSpace to analyze publication years, countries, institutions, journals, highly cited authors and publications, and co-occurrence and citation bursts of keywords.ResultsA total of 1,828 articles and reviews on vitamin D and reproductive health published between 2012 and 2021 were identified. The annual publication outputs showed steady growth, with the most publications (272) and citations (7,097) in 2021. The United States contributed the most publications (458) and had the highest h-index (58). In terms of the number of publications and h-index, the journal named Nutrients ranked first. Nutrition dietetics, obstetrics gynecology, and endocrinology metabolism were three well-represented disciplines in research on vitamin D and reproductive health. Hollis BW, Wagner CL, and Litonjua AA were the top three most productive authors in this field during the last decade. Apart from vitamin D, the five keywords with the most frequent occurrence were vitamin D deficiency, pregnancy, risk, vitamin D supplementation, and 25-hydroxyvitamin D. Keyword citation burst analysis revealed that low birth weight, adipose tissue, marker, and embryo had a citation burst lasting until 2021.ConclusionIn conclusion, vitamin D has received continuous attention in the field of reproductive health, and there appears to have a higher level of research in North America. Multidisciplinary intersection contributed to the in-depth exploration in this field. And the effect of maternal vitamin D levels on fetal lipid metabolism and the prediction of fertility by vitamin D-related markers might be hotspots for the research.

Global trends and current status in pheochromocytoma: a bibliometric analysis of publications in the last 20 years

“…What’s more, the scientific contribution of a researcher can be assessed using the H index. It denotes that a researcher has produced H articles, and each of those papers has received at least H citations from other publications ( 14 ). Additionally, it can also define the publication output of a country/region, institution or journal ( 15 ).…”

Global trends and current status of distraction osteogenesis: Bibliometric analysis of publications from 1980 to 2021

“…Sum of times cited and average citations per item reflects the level of attention ( Taubes, 1993 ). The H-index reflects the number and quality of an author’s publications, which means that a scholar has published H papers, each of which has been cited at least H times by other publications ( Roldan-Valadez et al, 2019 ; Lu et al, 2022 ). In addition, it can now also define the publication quality of a country/region, institution or journal ( Noruzi et al, 2022 ).…”

“…The search terms were TS = ("distraction osteogenesis" OR "bone lengthening") and document types: (Article OR Review). We selected publications with publication dates ranging from 1 January 1980 to 31 December 2021. cited at least H times by other publications (Roldan-Valadez et al, 2019;Lu et al, 2022). In addition, it can now also define the publication quality of a country/region, institution or journal (Noruzi et al, 2022).…”
