Research hotspots and frontiers of childhood hypertension

  Objective  To analyze the research status, hotspots and frontier progress of hypertension in children in English and Chinese literature, so as to provide reference for the early prevention of hypertension in children.  Methods  The Web of Science core collection database and CNKI database were searched to collect the literature related to the study of hypertension in children from 2000 to 2021, and the CiteSpace 5.8.R3 and VOSviewer 1.6.18 visualization tools were used to analyze the literature characteristics including publications, authors, regions, institutional cooperation, research hotspots and frontiers.  Results  A total of 22 687 English studies and 4 440 Chinese studies were finally included. According to the analysis results, the number of articles published on hypertension in children was on the rise. The published English articles were mainly University of Toronto and University of Colorado. The main publishing institution of Chinese articles was the First Affiliated Hospital of Peking University. The United States and China took the lead in the number of core journals published in the field of hypertension in children, the United States ranked first in terms of the influence of publications. Keyword co-occurrence analysis showed that the high-frequency keywords in the English literature included prevalence, risk, obesity, risk factor, body mass index, insulin resistance, overweight, metabolic syndrome, cardiovascular disease and mortality. Chinese high-frequency keywords in the literature include obesity, risk factors, adiposis, influencing factors, overweight, prevalence, diabetes, treatment, health education and body mass index. The analysis of keywords showed that 25 burst terms were obtained separately in English and Chinese literature.  Conclusion  In recent years, the research interest on hypertension in children continues to grow and keeps updated, with the research scope expanding significantly, regarding obesity, diabetes and cardiovascular diseases.
