Objective To understand the status quo of medical students' integrity in examinations and to explore the influencing factors. Methods 2013-2015 undergraduate students from Clinical Medi-cine, Preventive Medicine and other professional subjects were included in Shanxi Medical University. A total of 221 questionnaires were issued for each grade by stratified random sampling. The database was built with EpiData 3.1. All statical analyses were performed with SPSS software (version 22.0) by means of chi-square test and binary logistic regression. Results Among the 600 medical students, 16.5% of the students had cheating. A statistically significant difference was observed in the cheating rate among the medical stu-dents in terms of gender, grade, academic performance, medical knowledge, memory, family factors, and invigilators' attitude (P<0.05). Litter pressure from the family, the teacher's proctoring is rigorous invigilation, and top scores were the protective factors for medical students' cheating in exams. Conclusion Through the analysis of the influencing factors for the medical students' integrity in examinations, corresponding measures are formulated to provide reference for relevant medical personnel in various medical colleges and universities.
