Abstract:
Objective: To analyze the changing trends and development strategies of research hotspots in domestic and foreign epidemiological journals in the past decade, in order to promote the capacity building of the Chinese Journal of Epidemiology, enhance its academic influence, and improve its ability to serve authors. Methods: By searching the China National Knowledge Infrastructure and PubMed databases from 2015 to 2024, and using CiteSpace literature quantification analysis software, keyword co-occurrence analysis and cluster analysis were conducted on the Chinese Journal of Epidemiology (3 146 articles) and International Journal of Epidemiology, European Journal of Epidemiology, and American Journal of Epidemiology (4 988 articles) (3 international epidemiological journals) to explore the differences in research focus and hotspots between domestic and foreign journals, and to conduct keyword emergence knowledge graph analysis on the research progress and trends of epidemiological journals. Results: The annual average number of articles published in the Chinese Journal of Epidemiology from 2015 to 2024 is 320.4, with 26 authors having published ≥30 articles. The Chinese Journal of Epidemiology extracted a total of 436 keywords, and 3 international epidemiological journals extracted a total of 449 keywords, forming 13 and 11 clusters respectively. Both domestic and international journals focus on chronic non-communicable diseases and related influencing factors, but the Chinese Journal of Epidemiology places greater emphasis on locally adapted content and applied research. Keyword burst analysis reveals that the emerging intelligent methods theme appeared earlier in three international epidemiology journals compared to the Chinese Journal of Epidemiology, and in recent years, there has been increased attention to macro health policy topics such as "health disparities" and "health equity". Conclusions: The Chinese Journal of Epidemiology has developed distinctive features in localized adaptive content and applied research. In the future, it can enhance international alignment by advancing methodological frontiers and focusing on macro health policy themes, thereby elevating academic influence.
