*Proportions of obesity based on both WC ≥ 90/80 cm and BMI ≥ 28 kg/m2 (overlap between BMI- and WC- based obesity) is calculated as the number of obesity based on both WC ≥ 90/80 cm and BMI ≥ 28 kg/m2 divided by the number of obesity based on either WC ≥ 90/80 cm or BMI ≥ 28 kg/m2.

Likewise, proportions of exclusive general obesity and exclusive central obesity are calculated by the similar procedure.
