Visual analysis of domestic and international hotspots of nutritional research in children with tumors

Abstract

Objective: To analyze the literatures related to the nutrition of children with tumors at home and abroad, and sort out the current status, hotspots and frontiers of the research in this field, so as to provide a theoretical basis and reference for relevant research in China. Methods: The Web of Science and CNKI were searched for literatures related to nutrition of pediatric tumor patients since its establishment, and CiteSpace 6.1.R6 software was applied to visualize and analyze the nodes of countries, institutions and keywords. Results: A total of 53 articles in Chinese and 204 in English were included, with fluctuating upward trends in the number of publications. The largest number of publications with the strongest centrality was from the United States, and China was not ranked. Domestic publications were mainly from university-affiliated medical institutions, with Beijing Childrens Hospital Affiliated to Capital Medical University having the largest number of publications. Foreign publications were mainly from universities and medical institutions, with McMaster University and St. Jude Childrens Research Hospital having the largest number of publications. The main directions of domestic researchs were nutritional status and malnutrition, and the hot populations were children with malignant tumors and hematological tumors. The main directions of foreign researchs were nutritional status, malnutrition and body composition analysis, and the hot populations were children receiving chemotherapy or acute lymphoblastic leukemia. Conclusion: Through CiteSpace software to visualize the hotspots of children's oncology nutrition research at home and abroad directly, the relevant foreign researchs are more mature than the domestic, which can provide reference for researchers in China.
