Abstract： Objective To understand the current status and hotspots of international preventive medicine; To provide references for the research and discipline development of preventive medicine. Methods Literature about preventive medicine published from 2015 to 2019 in PubMed was searched and topic words and other information were extracted. Bibliometric analysis was carried out using bibliometrics methods， bibliographic information co-occurrence analysis system （BICOMB）， and graphical clustering toolkit （gCLUTO 1.0）.  Results Totally 1 435 articles about preventive medicine in 597 journals were retrieved. The top 3 countries were the United States， United Kingdom and Germany， and China ranked the fourteenth. A total of 4 696 keywords and sub-topics appeared， with a total of 16 886 occurrences. The 99 keywords and sub-topics with a cumulative frequency of ≥ 19 times were used as high-frequency words， with a total of 7 463 occurrences， accounting for 42.20% of the total frequency. Co-word clustering analysis found that high-frequency word clustering was divided into 6 categories. Research hotspots included psychological research on suicide， comparative research on preventive health care， research on occupation and health， research on occupational medical education resources， research on preventive health care strategies， and preventive research on cardiovascular diseases. Conclusion Based on the bibliometric analysis of international preventive medicine，

this article presents the current research status and hotspots of preventive medicine in recent years， and provides reference information for scientific research in China.
