Objective: To research the prevalence and influencing factors of asymptomatic arrhythmia among college students, and provide scientific basis for heart rate control and health management of asymptomatic arrhythmia among college students. Methods: Using cluster sampling method, 3 012 college students who studied in the First Clinical Medical College of Henan University of Traditional Chinese Medicine and the Second Clinical Medical College of Henan University of Traditional Chinese Medicine were selected as the research objects from September to November 2022. After entering school in autumn (September in 2022), all college students were investigated by questionnaire, and the general data and living habits of asymptomatic arrhythmia college students and normal college students were compared. Logistic regression was used to analyze the influencing factors of asymptomatic arrhythmia among college students. Results: A total of 62 patients with asymptomatic arrhythmia were found. The detection rates of the patients with body mass index(BMI)≥24.0 kg/m 2 , systolic blood pressure(SBP)≥120 mmHg, diastolic blood pressure(DBP)≥80 mmHg, family history of cardiovascular disease, smoking, drinking, exercising less than three times a week, heavy study pressure, irregular work and rest, depression tendency and anxiety tendency were 5.58%, 4.49%, 5.63%, 6.18%, 4.26%, 4.50%, 3.72%, 4.29%, 4.28%, 9.15%,9.03%, which were significantly higher than those of patients with BMI<24.0 kg/m 2, SBP＜120 mmHg, DBP<80 mmHg, no family history of cardiovascular disease, no smoking, no drinking, exercise more than three times a week, little study pressure, regular work and rest, no depression tendency and no anxiety tendency (1.20%, 1.37%, 1.35%, 1.53%, 1.55 %, 1.59%, 1.27%, 1.52%, 1.38%, 1.71%,1.71%), and the differences were statistically significant ( χ 2=45.33, 25.20, 37.74, 32.24, 16.69, 17.25, 19.57, 17.83, 22.36, 37.23,39.42, P <0.01). Logistic regression analysis showed that the higher of BMI,SBP and DBP, family history of cardiovascular disease, smoking, drinking, times of exercise, heavy study pressure, irregular work and rest, depression tendency and anxiety tendency were positively correlated with asymptomatic arrhythmia of college students ( P <0.05). Conclusions The higher of BMI and blood pressure, family history of cardiovascular diseases, bad living habits and psychological status are related to asymptomatic arrhythmia in college students. It is of great significance to control weight and blood pressure reasonably and maintain good living habits and mental state for preventing and improving asymptomatic arrhythmia.
