Visualization research hotspots and trends of foodborne diseases in China based on CiteSpace in 1985 -2022 / 公共卫生与预防医学

ABSTRACT

Objective To understand the research status of foodborne diseases in China from 1985 to 2022, and to explore the development process, research hotspots and frontier trends in this field. Methods With CNKI database as the search source, CiteSpace 6.1.R2 was used to analyze domestic research literature on foodborne diseases from 1985 to 2022. The author and organization cooperation map, and keyword co-occurrence and keyword timeline map were generated to comprehensively analyze the characteristics of foodborne diseases as well as research hotspots and cutting-edge trends in this field in China. Results A total of 2526 valid articles were obtained by exclusion criteria. According to the time distribution of articles from 1985-2022, the number of articles published before 2000 was small, and the annual number of articles published since 2000 had significantly increased. The largest number of articles was published by the China National Center for Food Safety Risk Assessment (51 articles), followed by the National Institution for Nutrition and Health of Chinese Center for Disease Control and Prevention (CDC) (38 articles). Most of the studies were conducted by national or government level research institutions in cooperation with provincial disease control and prevention centers. There was a close cooperation among different agencies. By the keyword cluster analysis, it was found that monitoring, Salmonella, and food safety were the concentrated research areas. The burst detection of keywords showed that food poisoning, sentinel hospital, and epidemic characteristics had the strongest citation burst. In recent years, the research hotspots were serotyping, drug resistance, virulence genes and so on. These keywords could reflect the investigation speed and laboratory level from a perspective. Conclusion The research on foodborne diseases in China is constantly increasing, and the research focus is gradually shifting from simple monitoring to improving the speed of outbreak investigation and laboratory level and speeding up the molecular tracing network to prevent more foodborne diseases.
