Abstract
Child nutrition has always been a global concern. This study performed visual analysis of 1,398 child nutrition highly cited papers (HCPs) from 2009 to 2019. The purpose of the study was to evaluate and present the performances of authors, journals, countries, institutions, top cited papers; to explore the hot topics, prospects, and to propose the future research directions on child nutrition. We used bibliometric methods to conduct in-depth statistical analysis of HCPs on child nutrition, showing research progress, trends and hot spots. We included HCPs on child nutrition from the Science Citation Index-Expanded (SCI-E) database February 7, 2020. Two tools, CiteSpace and VOSviewer, were used to conduct the bibliometric analyses. The results showed that, since 2011, the number of HCPs on child nutrition has increased rapidly. The top three contributors in this field were the USA, the UK and Canada. However, the contribution of developing countries was very limited. Intestinal microflora, food allergy, overweight and obesity were the three major research hotspots in this field. Results of this study provide valuable references for ongoing child nutrition related research, which may be interesting and noteworthy to the researchers involved.

A total of 1,398 highly cited papers (HCPs) were retrieved from Science Citation IndexExpanded (SCI-E), which includes 944 (67.525%) full-length research articles and 454 (32.475%) reviews
There is a significant correlation between the number of studies and the year with a high coefficient of determination (R2 = 0.9109)
Summary
Child nutrition has always been a global concern. The United Nations International Children’s Emergency Fund (UNICEF) released a report in 2019 about children, food and nutrition, entitled “The State of the World’s Children in 2019” [1]. The report mentioned that one-third of the world’s children under the age of five still cannot get the nutrition they need to grow up currently. Studies have shown that the average lifetime income loss per child with growth retardation was $ 1,400, and in developed countries, it was as high as $ 30,000 [7]. Overweight and obesity-related diseases, including heart disease, cancer, diabetes, and chronic respiratory diseases, was projected to cost more than $7 trillion in low and middle-income countries between 2011 and 2025 [7,8,9,10,11,12]
