1. Data source: Statistics Canada, National Population Health Survey, 1994/95, 1996/97 and 1998/99, cross sectional sample, health file
2. Body mass index (BMI-International standard), which relates weight to height, is a common method of determining if an individual's weight is in a healthy range based on their height.
3. Body mass index (BMI-International standard) is calculated as follows: weight in kilograms divided by height in metres squared.
4. The index is: under 18.5 (underweight), 18.5-24.9 (acceptable weight), 25.0-29.9 (overweight) and 30.0 or higher (obese).
5. Data with sampling variability (coefficient of variation) of greater than 33.3% were suppressed (- -); therefore, numbers in various aggregations may not sum to the totals.
6. Bootstrapping techniques were used to produce the coefficient of variation (CV) and 95% confidence intervals (CIs).
7. Data with a coefficient of variation (CV) from 16.6% to 33.3% are identified by an (E) and should be interpreted with caution.
8. Data with a coefficient of variation (CV) greater than 33.3% were suppressed (F) due to extreme sampling variability.
9. CANSIM table number 01040009.
