Diabetes status is defined at second examination( posterior to 5 years of the baseline).
†
We defined obesity condition with a combination of BMI and waist circumference criteria. Extremely obesity was defined as BMI≥40 kg/m2 (men and women), or waist circumference ≥50 inch (men) or ≥49 inch (women) while “obesity” was BMI ≥30 kg/m2 but <40 kg/m2 (men and women), or waist circumference ≥40 inch but <50 inch (men) or ≥35 but <49 inch (women). Overweight was BMI ≥25 kg/m2 but < 30 kg/m2 (men and women), or waist circumference ≥37inch but < 40 inch (men) or ≥31.5 but < 35 inch (women).
