1. Data source: Statistics Canada, Canadian Community Health Survey, 2000/01
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. Health regions are defined by provincial governments as the areas of responsibility for regional health boards (i.e., legislated) or as regions of interest to health care authorities.
10. A "peer group" is a grouping of health regions that have similar social and economic characteristics.
11. In Newfoundland and Labrador, health regions are generally referred to as Health and Community Services (HCS) regions.
12. In Prince Edward Island, the two health regions divide the province into urban and rural components.
13. Prince Edward Island has defined these health regions for statistical purposes only; they bear no resemblance to the boundaries of the five actual administrative health regions.
14. In Nova Scotia, health regions are known as "health zones" and relate to the province's administrative health region boundaries.
15. In Ontario, Public Health Units (PHU) administer health promotion and disease prevention programs, and District Health Councils (DHC) are advisory, health planning organizations.
16. Because of the small population of Churchill, Manitoba (population: 1,110 in 1996), the Canadian Community Health Survey only collects data for the aggregation of Burntwood/Churchill (regions 4680, 4690).
17. In Saskatchewan, "service areas" (SA) have been created from groupings of the 33 health districts.
18. In Alberta, health regions are referred to as Health Authorities (HA) or Regional Health Authorities (RHA).
19. The following symbols are used in Statistics Canada publications: (..) for figures not available and (...) for figures not appropriate or not applicable.
