Background : The number of patients with cardiovascular disease (CVD) in Japan continues to increase with population aging. Since 2020, the Tokushima Prefecture has implemented universal 12-lead electrocardiography (ECG) screening during specific health checkups to facilitate the early detection of CVD. This study aimed to identify factors associated with ECG abnormalities. Methods : Individuals who underwent the 2020 Tokushima Specific Health Checkup were included in this study. Participant characteristics were compared according to the presence of atrial fibrillation (AF) and pathological Q waves (PQW). Logistic regression analyses were conducted to identify associated factors. Results : Among the 54,368 participants (median age, 71 years ; 43.2% men), 538 (1.0%) had AF and 700 (1.3%) had PQW. AF was positively associated with male sex, older age, being overweight and obese, hypertension, prediabetes, and chronic kidney disease (CKD), and negatively associated with hypertriglyceridemia and hyper-low-density lipoprotein cholesterolemia. PQW was positively associated with male sex, older age, being underweight, higher BMI, hypertension, diabetes, dyslipidemia treatment, and CKD, and negatively associated with being overweight. Conclusion : Older age, hypertension, and class ≥ II obesity were positively associated with both AF and PQW. Prediabetes was positively associated with AF, whereas diabetes mellitus was positively associated with PQW. J. Med. Invest. 73 : 390-397, August, 2026
