Skill:
• Determination of body mass index by calculation or use of a nomogram
The body mass index (BMI) provides a measure of relative mass based on the weight and height of the individual
- It is commonly used as a screening tool to identify potential weight problems in sedentary adults
Body mass index can be calculated according to the following formula:
BMI ranges from underweight to obese, according to predetermined values based on an average adult population
- BMI values are not a valid indicator for pregnant women or professional athletes with atypical muscle / fat ratios
- BMI calculations should not be used as a diagnostic tool and should be used in conjunction with other measurements

Nomograms
An alternative way of calculating body mass index is by using an alignment chart (nomogram)
- Nomograms display height and weight on perpendicular axes and then assign BMI values to colour coded regions
