overweight to a degree which causes medical complications

KEY CONCEPT: 

Determination of body mass index by calculation or use of a nomogram.

BMI calculator 

Body Mass Index (BMI) is utilized as a  screening tool to identify potential weight problems. Despite this BMI is not a diagnostic tool.  More data needs to be collected in order to determine if the excess weight is a health risk.

 

BMI is a standard scale for all people; however there are limitations as women and men deposit weight in different ways and areas.

 

Furthermore, muscles have a heavier density than fat- they weigh more, BMI does not consider this. 

 

Other data which is needed: 

 

•skinfold thickness measurements

•evaluations of diet

•physical activity

•and family history 

 

(refer to table A)

Calculation worked example 

Figure A "monogram" 

An alternative to calculating the BMI is a nomogram.

 

Using a ruler, draw a line from the body mass (weight) to the height of the person.

 

The BMI of the person can be seen from where it intersects the W/HT line. (Figure A)
