Model 1: adjusted for age, gender, current smoking, current drinking, and physical activity.
Model 2: adjusted for variables in model 1, plus WC as a confounding factor. OR of WC (95% CI 1.07 to 1.11, p<0.001).
Model 3: adjusted for variables in model 2, plus HOMA-IR as a confounding factor. OR of HOMA-IR (95% CI 2.11 to 3.01, p<0.001).
*For p<0.05.
†For p<0.001.
HOMA-IR, homeostasis model assessment of insulin resistance; WC, waist circumference.
