目的通过多元统计和社会网络分析法中主题词共现的方式,研究中国儿童保健学科知识发展和分布,研究学科知识聚类,预测未来发展趋势。方法检索《中华儿科杂志》、《临床儿科杂志》、《中国实用儿科杂志》和《中国儿童保健杂志》,双人手工筛选儿童保健相关文献,按照文献数量和中国人均GDP水平分为1978至1994年、～2003年和～2011年3个阶段,使用EndnoteX4软件提取主题词,建立共词矩阵;使用SPSS17.0软件对共现矩阵进行转换、降维和聚类分析,并根据聚类分析结果绘制战略坐标图;使用Ucinet6.0软件绘制可视化网络图形。结果共提取文献5771篇,成功建立并直观展示了中国儿童保健学科知识可视化图谱及发展趋势。1978至1994年17年儿童保健发文总量162篇（年均9.5篇）,1995年后17年发文总量5618篇（年均330篇）,后者是前者发文总量的34.8倍;1978年至累积发文近百篇历经了14年（1991年）,累积发文超千篇又经过了7年（1998年）,以后每3年约增加1000篇。1978至1994年阶段中国儿童保健学科发展缓慢,方向零散,聚类归纳欠佳,佝偻病研究突出。～2003年阶段以儿童营养性疾病为研究核心,聚类归纳较好,构建了中国儿童保健学科基本框架,新兴研究领域发展稍显不足。～2011年阶段儿童社会心理行为研究成为核心,研究方法更加科学,各个聚类发展较之前平衡,知识更新迅速。结论中国儿童保健学科研究起步于20世纪90年代初,新千年后有了长足的进步,知识网络是一个逐渐完善的过程,并与国家的重视和经济发展相吻合。儿童保健研究方法学和儿童心理和社会行为发育规律等8个聚类形成了目前中国儿童保健学科架构,其中儿童发育和流行病学为最核心主题词。

英文摘要：

Objective To study the subject domain knowledge of discipline development of children health care in our country using multiple statistical and social network analysis, build visualized knowledge-mapping, and then predict the development trends in the future.Methods Search had been done according to the journal＇s name of Chinese Journal of Pediatrics, Journal of Clinical Pediatrics, Chinese Journal of Practical Pediatrics and Chinese Journal of Children Health Care. Two individual investigators then selected articles out about children health care from the entire searching results respectively. According to the native per capita GDP, the whole period was divided into three stages, 1978-1994, -2003 and -2011. After core had been characterized by Endnote X4 software in each stage, the co-occurrence matrix was built. Transformation, dimensionality reduction and clustering of the co-occurrence matrix were finished by SPSS 17.0 software, leading to the strategic plot to be built. The visualized network images were drawn using Ucinet 6.0 software.Results Totally 5 771 articles about children health care were included. The visualized domain knowledge-mapping was successfully built, and it directly reflected the structure of knowledge-mapping of the discipline development, and the key clusters were formed as well. Totally 162 articles were identified in the first 17 years （1978-1994, average 9.5 articles per year）, and 5 618 articles were enrolled in the second 17 years （1995-2011, average 330.0 articles per year）, which was 34.8 times of the number of articles in the previous period. It took 14 years （1978-1991） for the number of the articles accumulating to 100, and another more 7 years （1992-1998） to accumulate the number to 1 000. Then about 1 000 articles were published in every 3 years. In 1978-1994, the development of children health care headed slowly with fragmented directions, and the cluster results were poor, except the research of rickets, which revealed a relatively highlight. In the time
