Abstract: Objective To analyze the international research hotspots of pediatric obesity through the bibliometric analysis,so as to provide reference for grasping the future research area on pediatric obesity. Methods Pediatric obesity was used as the mesh term in searching of published international literature related with pediatric obesity in PubMed database from 2013.Then topic words and sub-topic words of literature on pediatric obesity were retrieved by bibliographic items Co-occurrence matrix builder(BICOMB) and the matrix of the topic words and sub-topic words was generated.Bi-clustering analysis of the matrix was carried out using gCLUTO software,then visual mountain graph and tree diagram were generated further. Results A total of 6 546 literature was included in PubMed since 2013.The number of published literature increased from 2013 and reached a peak in 2016.Results of the cluster analysis showed that international research focus mainly concentrated on six clusters, including psychology, intervention, diagnosis and epidemiology, etiology and risk factors, physiopathology and complications, and health promotion and treatment of pediatric obesity.Intervention, diagnosis and epidemiology of pediatric obesity were the core hotspots in recent years, with the large number of literature and highly consistent research theme compared with other clusters. Conclusionss The number of literature on pediatric obesity has increased recently.International research hotspots include psychology, etiology and risk factors, diagnosis and epidemiology, treatment, intervention,physiopathology and complications of pediatric obesity.Intervention, diagnosis and epidemiology of pediatric obesity are the core hotspots in recent years.

摘要: 目的 使用文献计量分析方法,分析现阶段儿童肥胖的国际研究热点,为把握该领域今后研究方向提供参考依据。方法 以儿童肥胖为主题词,检索2013年1月1日至今美国医学文摘(PubMed) 中在国际上发表的儿童肥胖相关文献,利用书目共现分析系统提取文献的主要主题词和副主题词,生成主要主题词和副主题词的词篇矩阵;使用 gCLUTO 软件对词篇矩阵进行双向聚类分析,并进一步生成可视化山丘图及可视化树状图。结果 2013年1月1日-2019年6月18日PubMed中共收录儿童肥胖相关文献6 546篇。2013年起儿童肥胖研究发表文章数量不断增加,于2016年发表文章数量达到高峰。聚类分析结果显示,国际研究热点主要集中在心理、干预、诊断及流行病学、病因及危险因素、病理生理机制及并发症、健康促进及治疗6个聚类中,其中以儿童肥胖的干预和诊断及其流行病学为研究核心热点。这两个聚类内的文章数量多,文章之间的研究主题高度一致。结论 2013年起儿童肥胖研究发表文章数量不断增加。儿童肥胖的心理、干预、诊断及流行病学、病因及危险因素、病理生理机制及并发症、健康促进及治疗是国际研究热点,而儿童肥胖的干预和儿童肥胖的诊断及其流行病学为研究核心热点。
