Abstract：OBJECTIVE: Inadequate postnatal nutritional support is an important factor contributing to growth failure, which leads to poor neurological outcome. In this study, co-word analysis was used to investigate the research on nutrition of premature infants over the last six years in China, describe the research trend in this field in China, and provide possible directions for future research. METHODS: A literature search was performed in January 2013 using the CNKI database and the key words “preterm infant” and “nutrition”. A total of 772 articles were retrieved. Then high-frequency key words were extracted using Excel 2010 to create a co-occurrence matrix. Finally, a visualized network was built using Ucinet 6.0. RESULTS: The knowledge domain map of research on nutritional support for premature infants in China showed that the major topic of relevant research is still the combination of parenteral nutrition and enteral nutrition, with the goal of maintaining appropriate growth rates in premature infants. Researchers have paid much attention to the adverse effects of parenteral nutrition. Feeding intolerance is still the main problem in nutritional support, especially enteral nutrition, for premature infants. CONCLUSIONS: A visualized network of current research on nutrition of premature infants in China has been created, and a knowledge domain map has been drawn to reflect the hot topics in this field of study over the last six years.
