Bibliometric overview of the Tehran Lipid and Glucose Study (TLGS) publications from 2000 to 2022.

ABSTRACT

Aim: The present study was conducted to analyze the publications of the Tehran Lipid and Glucose Study (TLGS) and assess its scientific productions during the last 23 years. Methods: The required data were retrieved from the Scopus database. The advanced search was chosen, and the search query included terms related to the TLGS. Search and retrieval of data were conducted on August 30, 2022. Bibliometric indicators have been used at three levels in this research including the level of documents, journals, and authors. Also, the knowledge structure of this set was analyzed at the level of social structure and the level of conceptual structure. Data analysis and visualizations was performed using Bibliometrix and VOSviewer software. Results: A total of 870 documents related to the TLGS have been indexed in the Scopus from 2000 to 2022, and 1148 authors have participated in the relevant studies. 66.4% of the TLGS documents were published in journals with Q1 subject area quartiles. There was an annual growth rate of 20% and average citations per document of 16.5. There was a co-authorship per document of 5.6 and an international co-authorship of 8.7%. According to the co-occurrence network for keywords, the most common areas in the TLGS published documents were nutrition, epidemiologic issues, cardiometabolic-related biomarkers, diabetes, hypertension, lifestyle variables and genetic studies. Conclusion: Over the past 23 years, the TLGS has successfully addressed a wide range of inquiries pertaining to cardiometabolic and nutritional issues in Iran. The remarkable achievements of the TLGS act as a catalyst, advocating for the planning and implementation of additional cohort studies that specifically focus on non-communicable diseases within the Iranian population.
