目的 了解我国生命早期1 000天领域的研究现状,把握该领域的研究热点和前沿,为后续开展深入研究提供参考。方法 检索1993-2018年CNKI期刊全文数据库中我国生命早期1 000天的相关文献,运用CiteSpace软件绘制科学知识图谱进行可视化分析。结果 我国生命早期1 000天领域的发文量整体呈上升的趋势;研究作者较少、合作关系简单,发文量最多的是洪建国;研究机构分布较分散,研究机构之间缺乏学术交流与合作,发文量最多的是重庆医科大学及其附属机构;“生命早期”、“营养不良”是该领域的研究热点;“胰岛素抵抗”、“营养”、“营养不良”、“儿童”和“饥荒”是该领域的研究前沿;结合关键词共现图谱和聚类时间线图可将该领域的发展进程分为1993-2005、2006-2012、2013-2018年三个阶段。结论 我国生命早期1 000天领域的研究正繁荣发展,但研究力量薄弱,建议加强科研人员的投入和机构间的学术合作,围绕生命早期营养不良的相关研究还需深入展开。
Abstract
Objective To understand the research status of the first 1 000 days of early life in China, and to grasp the research hotspots and frontiers in this field, so as to provide reference for further researches in the future. Method Relevant literature on the first 1 000 days of early life in the CNKI full-text database from 1993 to 2018 was retrieved, and CiteSpace was used to draw a scientific knowledge map for visual analysis. Results The number of articles published in the field of researches on the first 1 000 days of early life in China showed an overall upward trend.There were few research authors and simple cooperative relations, and HONG Jian-guo had the most publications.The distribution of research institutions was scattered, and there was a lack of academic communications and cooperation between research institutions.Publications on the first 1 000 days in life from Chongqing Medical University and the Affiliated Institutions were the most.Terms including "early life" and "malnutrition" were the research hotspots in this field, "insulin resistance", "nutrition", "malnutrition", "children" and "famine" were the research frontiers in this field.Finally the timeline chart on the development process of this field can be divided into 1993—2005, 2006—2012, 2013—2018 three stages by combining the keyword co-occurrence map with clustering. Conclusions Researches on the first 1 000 days of early life in China is booming, but the research strength is weak.It is recommended to strengthen the input of scientific researchers and academic cooperation among different institutions.And related researches on malnutrition in early life need to be further developed.
