Background Higher height and weight are known to be associated with higher risk of atrial fibrillation ( AF ); however, whether the is related abdominal obesity unclear. Methods Results We studied 501 690 adults (mean age: 47.6±14.3 years; 250 664 women [50.0%]) without baseline in National Sample Cohort released by Health Insurance Service Korea. Body mass index (underweight defined as <18.5; normal, 18.5 <25.0; overweight, 25.0 <30.0; obese, ≥30.0) waist circumference (abdominal ≥90 cm for men ≥80 women) were evaluated. During a mean follow‐up 3.9±1.3 years, 3443 participants (1432 [41.6%]) developed . In multivariable models adjusted clinical variables, underweight, obese individuals increased 21% (95% confidence interval, 1.01–1.45, P =0.043), 14% 1.06–1.23, <0.001), 52% 1.30–1.78, respectively, compared those normal body index. confounder‐adjusted hazards was 18% 1.10–1.27, <0.001). The present abdominally regardless except group. subgroup analysis, conferred new‐onset , particularly comorbidities. Conclusions Abdominal an important, potentially modifiable factor nonobese Asian persons. These data suggest that interventions decrease may reduce population burden
