1. Data source: Statistics Canada, Canadian Community Health Survey, Nutrition, 2004
2. Body mass index (BMI) is calculated by dividing the respondent's body weight (in kilograms) by their height (in metres) squared.
3. The index is: neither overweight nor obese; overweight; obese.
4. Body mass index (BMI) for children is different from that of adults as they are still maturing. This variable classifies the measured BMI of children aged 2 to 17 as "obese" or "overweight" according to the age-and-sex-specific BMI cut-off points as defined by Cole and others. The Cole cut-off points are based on pooled international data (Brazil, Great Britain, Hong Kong, Netherlands, Singapore and United States) for BMI and linked to the internationally accepted adult BMI cut-off points of 25 (overweight) and 30 (obese). Respondents who do not fall within the categories of "obese" or "overweight" (as defined by Cole and others) have been classified by the Canadian Community Health Survey (CCHS) as "neither overweight nor obese".
5. Bootstrapping techniques were used to produce the coefficient of variation (CV) and 95% confidence intervals (CIs).
6. Data with a coefficient of variation (CV) from 16.6% to 33.3% are identified by an (E) and should be interpreted with caution.
7. Data with a coefficient of variation (CV) greater than 33.3% were suppressed (F) due to extreme sampling variability.
