Abstract: Objective To understand the research status of the first 1 000 days of early life in China, and to grasp the research hotspots and frontiers in this field, so as to provide reference for further researches in the future. Method Relevant literature on the first 1 000 days of early life in the CNKI full-text database from 1993 to 2018 was retrieved, and CiteSpace was used to draw a scientific knowledge map for visual analysis. Results The number of articles published in the field of researches on the first 1 000 days of early life in China showed an overall upward trend.There were few research authors and simple cooperative relations, and HONG Jian-guo had the most publications.The distribution of research institutions was scattered, and there was a lack of academic communications and cooperation between research institutions.Publications on the first 1 000 days in life from Chongqing Medical University and the Affiliated Institutions were the most.Terms including "early life" and "malnutrition" were the research hotspots in this field, "insulin resistance", "nutrition", "malnutrition", "children" and "famine" were the research frontiers in this field.Finally the timeline chart on the development process of this field can be divided into 1993—2005, 2006—2012, 2013—2018 three stages by combining the keyword co-occurrence map with clustering. Conclusions Researches on the first 1 000 days of early life in China is booming, but the research strength is weak.It is recommended to strengthen the input of scientific researchers and academic cooperation among different institutions.And related researches on malnutrition in early life need to be further developed.
