Elevated levels of body mass index and waist circumference, but not high variability, are associated with an increased risk of atrial fibrillation

Table 3 Associations of variability in BMI and WC with risk of atrial fibrillation

Variability measures	Multivariable adjusted HR (95% CI)
Variability measures	BMI	WC
VIM	0.96 (0.86, 1.07)	1.02 (0.99, 1.05)
CV	0.99 (0.96, 1.02)	1.02 (0.99, 1.04)
ARV	0.97 (0.89, 1.05)	1.02 (0.99, 1.03)
SD	0.98 (0.89, 1.09)	1.02 (0.99, 1.04)

Abbreviations: ARV Average real variability; BMI Body mass index, CV Coefficient of variation, CI Confidence interval, HR Hazard ratio, SD Standard deviation, VIM Variability independent of the mean, WC Waist circumference
All models were adjusted for age, sex, physical activity, smoking status, alcohol drinking status, low-density lipoprotein cholesterol, heart rate, hypertension, and diabetes
