Calculations

According to the World Health Organization (WHO) and Health Canada guidelines, the index for body weight classification for the population aged 18 and older is:
- less than 18.50 (underweight);
- 18.50 to 24.99 (normal weight);
- 25.00 to 29.99 (overweight);
- 30.00 to 34.99 (obese, class I);
- 35.00 to 39.99 (obese, class II);
- 40.00 or greater (obese, class III).

The population aged 5 to 17 is classified as 'overweight' or 'obese' according to age and sex specific cut-off points defined by the World Health Organization.
