How It Works & Formula
Adjusted Body Weight (ABW) is used for patients who are overweight or obese, as it provides a more accurate estimation of lean body mass for medication dosing and nutritional requirements.
The formula used is:
ABW = IBW + 0.4 × (Actual Weight - IBW)
Where IBW (Ideal Body Weight) is calculated using the selected formula:
- Devine: Male: 50 kg + 2.3 kg per inch over 5 feet; Female: 45.5 kg + 2.3 kg per inch over 5 feet
- Robinson: Male: 52 kg + 1.9 kg per inch over 5 feet; Female: 49 kg + 1.7 kg per inch over 5 feet
- Miller: Male: 56.2 kg + 1.41 kg per inch over 5 feet; Female: 53.1 kg + 1.36 kg per inch over 5 feet
- Hamwi: Male: 48 kg + 2.7 kg per inch over 5 feet; Female: 45.5 kg + 2.2 kg per inch over 5 feet
