Abstract: Objective To understand the excessive resting heart rate （RHR） of college freshmen and related influencing factors， so as to provide scientific basis for primary prevention of cardiovascular diseases. Methods Based on the physical examination of 12 849 freshmen enrolled in Jianghan University from 2015 to 2017，the detection rate of excessive RHR and the factors affecting the excessive RHR were analyzed. Objective Results Excessive RHR detection rate of 12 849 freshmen was 2. 23%，2. 26% for male and 2. 30% for female （χ² = 0. 025，P > 0. 05）；excessive RHR detection rates in 2015，2016 and 2017 were 1. 85%，2. 30% and 2. 73%，respectively，which showed an increasing trend year by year （χ² = 7. 558，P < 0. 05）；The detection rates of excessive RHR of college freshmen in hypertension group，overweight and obesity group，urban group，late night，family history of cardiovascular disease group were higher than those of non-hypertension group，nonoverweight and non-obesity group，rural group，non-late night，non-family history of cardiovascular disease group（χ² values were 122. 485，8. 566，11. 263，78. 498，91. 192，P < 0. 05）. The multiple stepwise regression analysis showed that hypertension，obesity，staying up late，lack of physical exercise，town and family history of cardiovascular disease were risk factors for the excessive RHR of college freshmen（P < 0. 05）. Conclusion The excessive RHR of freshman is related to many factors，the prevention and treatment of cardiovascular diseases should be started from the youth and a healthy lifestyle should be advocated.
