* Relative risks (95% CI) were adjusted for age, baseline weight, smoking, physical activity, education level and medication use.
^† Only subjects free of mentioned component at baseline were entered in each analysis.
WC: waist circumference, TG: triglyceride, FPG: fasting plasma glucose, BP: blood pressure
