  1. Abbreviations: WC waist circumference, BMI body mass index
  2. Prevalence estimates are represented as percentages
  3. Asian-specific BMI threshold for obesity is defined as BMI of 27.5 kg/m2 (Asian-specific general obesity)
  4. Asian-specific WC threshold for obesity is defined as WC of ≥102 cm for men and ≥88 cm for women (Asian-specific abdominal obesity, noting that these thresholds are the same as the international thresholds)
  5. Not obese (BMI < 27.5, WC < 102 for men, WC < 88 for women), obese by WC only (BMI < 27.5, WC ≥ 102 for men, WC ≥ 88 for women), obese by both BMI and WC (BMI ≥ 27.5, WC ≥ 102 for men, WC ≥ 88 for women) and obese by BMI only (BMI ≥ 27.5, WC < 102 for men, WC < 88 for women)
