Abstract

Objective: To determine the prevalence and associated factors of cardiac arrhythmias among students participating in sports clubs at Can Tho University of Medicine and Pharmacy. Subjects and Methods: A cross-sectional descriptive study was conducted on 75 students. Anthropometric indices, blood pressure, frequency, and duration of physical activity were recorded. Cardiac arrhythmias were diagnosed using resting electrocardiograms (ECG). Chi-square tests and univariate/multivariate logistic regression analyses were performed to identify associated factors. Results: The prevalence of cardiac arrhythmias was 15.79%, primarily including sinus tachycardia (11.84%) and multifocal atrial tachycardia (3.95%). Arrhythmias were significantly associated with female gender (p = 0.0004) and age ≤25 (p = 0.03). In multivariate logistic regression, age >25 was an independent protective factor (OR = 0.15; 95% CI: 0.03–0.86; p = 0.03). Anthropometric indicators such as waist circumference, WHR, blood pressure, and physical activity showed no statistically significant association with arrhythmias, although increased waist circumference showed a trend toward increased risk (OR = 6.26; p = 0.11). Conclusion: Cardiac arrhythmias are relatively common among physically active students, particularly in females and younger individuals.
