目的 利用共词分析方法对近10年国内有关早产儿出院后营养的文献进行分析,深入探讨该领域的研究现状及进展,为进一步研究奠定基础。方法 在中国知网数据库以“早产儿”、“营养”或“喂养”、“出院”为主题词,检索并纳入符合研究标准的文献,利用Bicomb2对下载的文献进行关键词统计和分析,利用Ucinet6.0及Netdraw绘制共现分析图,将高频关键词之间的共现关系可视化。结果 共纳入文献72篇,提取高频关键词20个。通过共词分析得出,我国早产儿出院后营养的研究主要集中在早产儿尤其是低出生体重儿和小于胎龄儿生长发育的问题;营养支持方式以母乳喂养、早产儿出院后配方奶最为热门;而有关强化营养时间、辅食添加、营养状况对早产儿远期健康影响以及营养管理方法等方面的研究较少。结论 现阶段国内有关早产儿出院后营养的研究总体较少,其中以出院后营养支持对象与方式、近期生长发育状况的研究相对较多。在早产儿强化营养、辅食添加、营养状况对其远期健康影响以及出院后营养管理方法等方面,未来需要进一步的研究。
Abstract
Objective The co-word analysis was applied to analyze Chinese literatures on nutrition of premature infants after discharge published over the recent decade,aiming to explore the research status and progress of the field and provide a foundation for further studies. Methods Literatures on the Chinese National Knowledge Integrated Database were searched by using "premature infant","nutrition" or "feeding"," discharge" as subject headings,and those fitting in the criteria were included into the study.Keywords statistics and analysis were conducted by using Bicomb2,and a co-occurrence analysis diagram was drawn by using Ucinet 6.0 and Netdraw to visualize the co-occurrence between frequently occurred keywords. Results A total of 72 literatures were included and 20 high-frequency keywords were extracted for co-word analysis,revealing the correlations between the keywords.The results showed that studies on nutrition of premature infants after discharge in China focused on the growth and development of the low-birth-weight and small for gestational age infants.In the ways of nutritional support,the breastfeeding and post discharge formula were the most popular.However,the fortified nutrition time,the method and attention of adding the assisted food,the long-term influence due to growth defect,and the nutrition management method after discharge need further studies. Conclusions At present the domestic studies about the nutrition of premature infants after discharge are relatively less in general,and in which the nutritional support object and method are relatively more.In the future,we need further studies on the fortified nutrition,adding the assisted food,the long-term influence due to growth defect,the nutrition management method after discharge and so on
