description

Objective The area of pediatric hypertension (HTN) research has seen substantial progress over the last two decades, but no bibliometric analysis has yet been undertaken to describe these advances. This study aims to describe the published research examining HTN in children and adolescents from 2000 to 2018. Methods Articles were retrieved using PubMed and the Web of Science. Analyses were performed to quantify the evolution of scientific output, identifying the leading journals, authors, and countries as well as the existing collaboration networks. Likewise, we identified the most cited articles, describing their document type, main topic focus, and the age of the patients studied. Results In total, we identified 8317 articles in the Web of Science. The annual number of publications doubled over the study period. Articles were published in 1415 journals, mainly in the categories of Peripheral & Vascular Diseases and Pediatrics. The USA dominated scientific production in the field. Regarding researcher productivity, the top 202 authors participated in 20% of the articles, and there were 47 stable research clusters, with the largest component made up of 17 authors. Altogether, there were 145 most cited articles, with an irregular annual distribution; about half focus on HTN itself, while the rest study associated disorders and conditions. Conclusion This is the first study to analyze scientific output on HTN in children and adolescents. The snapshot that emerges is of a research area that is growing but is still in a relatively early phase of development.
