Abstract:
Objective:To explore the research characteristics of clinical nutrition in China across different periods by systematically analyzing the articles published in the Chinese Journal of Clinical Nutrition over three decades (1993–2024). Methods:We utilized the bibliometric tool VOSviewer to divide the articles published in the Chinese Journal of Clinical Nutrition from 1993 to 2024 into three stages: 1993–2001, 2002–2008, and 2009–2024, for which every two consecutive editorial boards were regarded as one stage. Keyword co-occurrence analysis was conducted and the authors were analyzed. Accordingly, knowledge graphs were drawn to reflect the research characteristics of clinical nutrition in China at various developmental stages. Results:Research on clinical nutrition research in China differed across different stages. From 1993 to 2001, research primarily focused on parenteral and enteral nutrition and nutritional support, exploring their applications for specific diseases. From 2002 to 2008, the content of research became more detailed, and evidence-based methodologies were widely adopted, promoting the transition of research from simple nutrition support to the analysis of nutrition intervention mechanisms and evidence-based practice. From 2009 to 2024, articles published in the Chinese Journal of Clinical Nutrition not only focused on traditional nutritional support and disease interventions but also introduced emerging standards and new diseases, involving more diseases and populations; additionally, the research hotspots extended to interdisciplinary fields, along with continuously evolved research methods and technologies. Conclusions:The evolution of articles published in the Chinese Journal of Clinical Nutrition over the past 32 years not only documented the developmental trajectory of Chinese clinical nutrition from basic technical specifications to precision medicine interventions but also offered a paradigm shift of the discipline from the introduction and digestion of technologies to the independent innovation in formulating clinical nutrition-related guidelines and expert consensuses.
