Obesity
Description
- Excess adiposity causing impaired health
- BMI is a screening tool, not a diagnosis - misclassifies muscular and older patients, and underestimates risk in South and East Asian populations
| BMI (kg/m2) | Class | Asian cut-offs |
|---|---|---|
| 25-29.9 | Overweight | 23-27.4 |
| 30-34.9 | Class I | >=27.5 |
| 35-39.9 | Class II | |
| >=40 | Class III |
- Waist circumference adds independent risk information at any BMI
- Increased risk: M >=94 cm, F >=80 cm; substantially increased M >=102 cm, F >=88 cm
- Edmonton Obesity Staging System (0-4) stages by actual disease burden, not weight - a better predictor of mortality than BMI and the better basis for intervention
