Abstract: Objectives To analyze the situation and influencing factors of overseas visits and exchanges among undergraduate clinical medicine students using data collected from China Medical Student Survey. Methods Descriptive analysis, chi-square test, Logit model were used. Results A total of 219 396 medical undergraduate students from 123 medical colleges across the country participated in the survey, of which only 2.0% had overseas visiting and exchange experiences. In terms of the likelihood of participating in overseas visits and exchanges, urban students were higher than rural students (β=0.405, P<0.001), students from families with an annual income of over 150 000 to 300 000 Yuan and over 300 000 Yuan exceeded those with an annual income of less than 10 000 Yuan (β=0.375, P<0.001;β=0.845, P<0.001),students whose universities located in western China were lower than those located in eastern China (β=-0.159, P<0.001), students who studying at universities affiliated to the central government were higher than those studying at universities affiliated to provincial sectors(β=0.305,P=0.039),students who studying at world-class university and discipline construction programs were higher than those who studying at independent colleges (β=0.493,P=0.009;β=0.546,P<0.001). Conclusions The proportion of medical undergraduate students who participated in overseas visits and exchanges is too low and should be steadily increased. The likelihood of medical students from disadvantaged groups participating in overseas visits and exchanges is relatively low, and it is necessary to improve the financial aid system to address this issue. In addition, there are significant differences in undergraduate medical students' overseas visits and exchanges among different types of universities, which should be taken seriously.
