1999~2018年巨大儿的相关研究分析

Relevant research on macrosomia from 1999 to 2018

目的分析巨大儿的相关研究现状及热点并预测其趋势.方法以1999~2018年SCI-E数据库收录论文为研究对象,运用文献计量学和VOS viewer数据可视化软件对纳入文献进行统计分析.结果1952篇纳入文献的分析结果显示:①每年巨大儿的相关研究论文发表数量总体呈增长趋势,美国与英国是该领域文献的主要贡献国家,美国是资助机构数和受资助文章发表数最多的国家,美国作者Caughey AB在该领域影响力相对较大;②我国在该领域的影响力逐渐增大,年度发文量于2018年超过美国位居第一,67.6%的文章受基金资助;③2009年后该领域出现多元化研究角度和研究方向,但研究的主要方向未发生变化,发表论文的总被引频次从2014年开始呈下降趋势.结论巨大儿研究领域一直为研究热点,我国巨大儿研究水平尚需进一步提高,且巨大儿发病的生物学机制尚需进一步探索.

Objective To analyze the status quo and hotspot of researches on macrosomia and to predict future research trends in this field.Methods Papers included in the SCI-E database from 1999 to 2018 were adopted as research objects,and were analyzed by bibliometric and VOS viewer data visualization software.Results A total of 1952 papers were enrolled.The results showed that:①The number of related papers was generally increased every year.The United States and the United Kingdom were the main contributors to the literatures in this field.The funding agencies and funded articles were the most in the United States.Caughey AB,coming from the United States,had rather a large influence.②The annual publication volume in China surpassed the United States and became the No.1 in 2018,and 67.6%of these articles were funded.③There appeared different research angles and directions after 2009,but the main direction had not changed.The total citation frequency of papers were declined since 2014.Conclusion The research of macrosomia is a hotspot always,but the research level in China needs to be further improved,and the biological pathogenesis of macrosomia remains to be further explored.
