儿童高血压研究热点与前沿分析

Research hotspots and frontiers of childhood hypertension

目的分析中英文文献中儿童高血压研究现状、热点及前沿进展,为儿童高血压的早期预防提供参考。方法检索Web of Science(WoS)核心合集数据库和中国知网数据库(CNKI),收集2000—2021年儿童高血压研究相关文献,运用CiteSpace 5.8.R3和VOSviewer 1.6.18可视化工具分析文献发文量、作者、地区、机构合作情况和研究热点与前沿。结果共纳入英文文献22687篇、中文文献4440篇,儿童高血压主题发文量总体呈上升趋势。英文文献的发文机构以多伦多大学、科罗拉多大学为主,中文文献的发文机构以北京大学第一医院儿科为主。美国和中国在儿童高血压领域所发表的核心期刊数量处于领先地位,美国的发文影响力居于首位。关键词共现分析表明,英文文献高频关键词有“prevalence”“risk”“obesity”“risk factor”“body mass index”“insulin resistance”“overweight”“metabolic syndrome”“cardiovascular disease”“mortality”等,中文文献高频关键词有肥胖、危险因素、肥胖症、影响因素、超重、患病率、糖尿病、治疗、健康教育、体质量指数等。关键词突现分析显示,英文、中文文献各得到25个突现词。结论近年来国内外学者对儿童高血压的研究热度持续上升,热点问题在不断更新、涉及的疾病范围也在不断扩大,尤其在肥胖、糖尿病和心血管疾病方面。

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 character-istics including publications authors regions institutional cooperation research hotspots and frontiers.Results A total of 22687 English studies and 4440 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 Colo-rado.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 lit-erature included prevalence risk obesity risk factor body mass index insulin resistance overweight metabolic syndrome car-diovascular disease and mortality.Chinese high-frequency keywords in the literature include obesity risk factors adiposis influen-cing 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 obesi-ty diabetes and cardiovascular diseases.
