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-Canadian 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-Canadian standard) is calculated as follows: weight in kilograms divided by height in metres squared.
4. The index is: under 20.0 (underweight), 20.0-24.9 (acceptable weight), 25.0-27.0 (some excess weight) and higher than 27.0 (overweight).
5. Population aged 20 to 64 excluding pregnant women and persons less than 3 feet (0.914 metres) tall or greater than 6 feet 11 inches (2.108 metres).
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 01040008.
