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.
