Bibliometric Analysis of Theses on Sustainable Nutrition in Türkiye

Abstract

As sustainability has become a central concern across various domains, scholarly interest in this field has grown substantially. Among these domains, sustainable nutrition has emerged as a particularly prominent area of inquiry. This study aims to analyze the content of these theses on sustainable nutrition. In this study, where the bibliometric analysis method was used, and data were obtained from the Türkiye Council of Higher Education (CoHE) Thesis Center. A total of 33 theses completed between 2017 and June 2025 were examined. Theses not registered on the CoHE Thesis Center were not included in this study. The university, institute and department, the language, the type of the thesis (master's or doctoral thesis), the year and keywords were recorded using Microsoft Excel. The data were analyzed using descriptive statistical methods. The findings showed that a large portion of theses on sustainable nutrition were prepared in the Nutrition and Dietetics Departments of universities (69.70%). As of 2023, there has been a significant increase in the number of theses written on the subject. Also, 93.94% of these were master's theses and 90.91% were written in Turkish. The universities where the most theses were prepared on the subject were Bahcesehir University, Istinye University and Baskent University. Although the number of theses completed on sustainable nutrition is increasing, this subject has not been sufficiently researched, especially in departments other than Nutrition and Dietetics. Doctoral-level theses on sustainable nutrition were found to be limited. This study offers a foundation for further interdisciplinary academic work and highlights areas requiring further research.
