Abstract: Objective To understand the current status and progress on researches regarding the impact of electronic waste (e-waste) on the health of pregnant women and children in foreign language literature,so as to provide theoretical basis and innovative ideas for further research in this field in China. Methods Based on bibliometrics Methods combined with information visualization,bibliographic information co-occurrence mining system(BICOMS) analysis software was used to extract and collate the information of topic words,and co-occurrence matrix was generated.NetDraw was used to arrange the relationships among the main headings and draw social network diagrams.Also,gCLUTO cluster analysis was used for clustering analysis.According to the actual clustering effect,the final choice of the main topic words gathered into three categories,visual surface maps and visualization matrix were generated. Results There were 5 018 studies regarding the impact of e-waste on the health of pregnant women and children.The number of studies was balanced in the distribution of age,journals,authors and countries.In 5 018 studies,there are 3 975 main subject words with substantial meaning,And the lower the frequency of main subject words was,the more the number of main keywords would be.Among them,there were 303 main subject words appearing more than 10 times,1 962 main subject words appeared once,and 32 main themes appeared more than 59 times,which was the main research direction of the impact of e-waste on pregnant women and children.The results of social network analysis showed that there were 14 high-frequency main keywords in the middle of the social network,with the largest centrality. Conclusions The impact of environmental pollution on disease,behavior and development in children and adolescents,the impact of maternal and occupational exposure to e-waste on disease are three key areas in the researches about the impact of e-waste on the health of pregnant women and children.In recent years,foreign researchers have gained great achievements on the above three aspects,however,there are still few studies on ways of affecting health of pregnant women,mechanism,preventive measures and prognosis research.In addition,the impact of e-waste on the health of pregnant women and children is very less-researched in China,so further research is warranted
