摘要
目的 分析近年来全球小于胎龄儿(small for gestational age infant,SGA)的研究现状、热点及前沿,梳理该领域发展脉络并预测未来发展趋势,为SGA研究及临床指导提供参考.方法 基于Web of Science(WOS)核心合集数据库,选择科学引文索引扩展(Science Citation Index Expanded,SCI-EXPANDED)及社会科学引文索引(Social Sciences Citation Index,SSCI),检索式为:(TS=("small for gestational age children"or"small for gestational age infant"or"small for gestational age")AND LA=(English)AND DT=(Article OR Review Article)),时间跨度为2012年1月1日至2022年8月16日.运用CiteSpace,v.6.1.R3.64-bit绘制国家、机构、作者及关键词共现图,关键词聚类图及突现图,探究全球SGA研究领域主题演化及热点.结果 共纳入6524篇文献,近年来,全球SGA研究文献年度发文量呈波动性上升趋势;综合中介中心性(0.15)和发文量(1859篇)分析,美国在该研究领域占主导优势;高产机构为卡罗林斯学院(Karolinska Institute,瑞典),以226篇文献稳居榜首;高产作者为NICOLAIDES K团队,主要研究方向为探索SGA的危险因素、SGA的早期有效筛查方法及如何降低SGA的患病率.关键词突现图发现,近3年的研究热点主要集中于流行病学研究和基因表达对妊娠结局影响的研究.结论 进一步开展临床多中心的SGA分子流行病学和基础研究,揭示SGA患病危险因素,以提高SGA三级预防及治疗效果,仍是产科和儿科医务人员共同努力的研究方向.
Abstract
Objective To analyze the research status,hotspots and frontiers of small for gestational age infant (SGA) worldwide in recent years,summarize the development context of this field and predict the future development trend,so as to provide reference for SGA research and clinical guidance.Method Based on the Web of Science (WOS) core collection database,Science Citation Index Expanded (SCI-EXPANDED) and Social Sciences Citation Index (SSCI) were selected.The retrieval form was:(TS=("small for gestational age children" or "small for gestational age infant" or "small for gestational age") AND LA=(English) AND DT=(Article OR Review Article)),it covered the period from January 1,2012 to August 16,2022.CiteSpace,v.6.1.R3.64-bit was used to draw the co-occurrence map of countries,institutions,authors and keywords,keyword clustering map and emergence word map,to explore the topic evolution and hotspots in the field of global SGA research field.Result A total of 6524 literatures were included.In recent years,the annual number of global SGA research papers showed a rising trend in volatility.Based on the analysis of betweenness centrality (0.15) and number of publications (1859 literatures),the United States has the leading advantage in this research field.The most prolific institution was Karolinska Institute (Sweden) with 226 literatures.The main research direction of the highly productive author was NICOLAIDES K team.The main research direction was to explore the risk factors of SGA,early and effective screening methods for SGA and how to reduce the prevalence of SGA.Keywords emergence word map showed that,in the past three years,the research hotspots had been focus on epidemiological studies and the effects of gene expression on pregnancy outcomes.Conclusion To further develop the clinical multi-center SGA molecular epidemiology and basic research,reveal the risk factors of SGA to improve the three-level prevention and treatment of SGA is still the research direction of obstetric and pediatric medical staff.
