Abstract: Objective To understand the current status and hotspot issues on the sleep in children through analtyzing for related literatures.Methods Literatures on sleep in children were retrived in PubMed from January 1st,2014 to February 28th 2019.Bibliographic information co-occurrence mining system (BICOMS) analysis software was used to extract and collate the information of topic words,and co-occurrence matrix was generated.Netdraw was used to arrange the relationships among the main headings and draw social network diagrams.And gCLUTO cluster analysis was used to generate visual surface maps and visualization matrix according to the actual clustering effect. Results Totally 2 070 studies on the sleep in children were included.And 34 main keywords with frequency greater than 28,were currently the main research directions of sleep in children,as well as the promotion of safe sleep.Finally,the hotspot issues were summarized in three aspects,including 1)Safe sleep in infants and the correlation of sleep with physical activity,obesity and dietary behavior; 2)Sleep circadian rhythm in children and its impact on growth and development; 3) Sleep disorders and its correlation with psychological and behavioral development. Conclusions There are few studies on the hazard mechanism of the effect of sleep circadian rhythm and sleep continuity on the mental and physical health of children.Further studies are warranted in this area to enrich related research in China.

摘要： 目的 分析儿童睡眠研究的相关文献,了解当前的研究现状及热点。方法 检索PubMed数据库2014年1月1日-2019年2月28日发表的有关儿童睡眠的文献,采用书目信息共现挖掘系统 (BICOMS)对主要主题词的信息进行抽取和整理,并生成共现矩阵;采用NetDraw按照中心度排列各主要主题词之间的关系,并绘制社会网络图;采用gCLUTO进行聚类分析,根据实际聚类效果,最终选择将主要主题词聚为3类,并生成可视化矩阵和可视化曲面图。结果 共检索儿童睡眠相关文献2 070篇,出现频次＞28次的主题词34个,通过分析获得儿童睡眠研究的3个研究热点:婴幼儿睡眠安全及睡眠与儿童健康身体活动、肥胖和饮食行为间的关系,不同儿童的睡眠/觉醒模式和昼夜节律及睡眠对儿童发育的影响,睡眠障碍与儿童心理行为发育。结论 目前探索儿童睡眠昼夜节律、睡眠持续性对儿童身心健康的影响机制、安全健康睡眠的促进等方面研究较少,后期需在此基础上加以创新,不断丰富我国在儿童睡眠方面的研究成果。
