Research trends in gestational diabetes mellitus in Southeast Asia: A bibliometric analysis (1975-2020).

AIMS

To determine the characteristics and trends of published articles in the field of gestational diabetes mellitus (GDM) in Southeast Asia (SEA) through a bibliometric analysis.

METHODS

Systematic review of literature on GDM in SEA countries was performed using the Ovid MEDLINE®, Scopus, and WPRIM databases between 1975 and 2020. All published studies on GDM conducted in or published by authors from any SEA country were included in our analysis. Bibliometric information was obtained from Scopus and bibliometrics diagrams were created using VOSviewer software.

RESULTS

A total of 322 articles were obtained in this study. The number of publications showed an upward trend starting 2011. The country with the greatest number of publications was Malaysia while The National University of Singapore was the most productive institution in GDM research in SEA. The focus of GDM research in SEA were on the prevalence, prevention, diagnosis, and pregnancy outcomes. GDP, research expenditure, and researchers per million people were positively correlated with research productivity and impact in GDM research in SEA.

CONCLUSIONS

This is the first bibliometric analysis on GDM in SEA countries. GDM research in SEA continued to increase in the past years but still lagged behind that of other regions. The SEA countries should consider increasing support for research to produce substantial research that can serve as basis for evidence-based and locally applicable GDM interventions.
