1. The survey excludes from its target population those living in the three territories, individuals living on Indian reserves or on Crown lands, residents of institutions, full-time members of the Canadian Armed Forces and residents of certain remote regions.
2. The table excludes pregnant or breastfeeding females, subject to another set of nutritional recommendations. The sample of pregnant or breastfeeding females is not large enough to allow for reliable estimates.
3. Characteristics based on the first 24-hour dietary recall (first day of interview) only.
4. The intake distribution was adjusted to remove within individual variability using Software of Intake Distribution Estimation (SIDE) (Iowa State University, 1996) and the method presented in Nusser SM, Carriquirry AL, Dodd KW, Fuller WA. "A semiparametric approach to estimating usual daily intake distributions". Journal of American Statistical Association 1996;91:1440-1449.
5. AMDR is the Acceptable Macronutrient Distribution Range, expressed as a percentage of total energy intake. Intakes inside the range are associated with a reduced risk of chronic disease while providing adequate intakes of essentials nutrients.
6. The lower threshold for Acceptable Macronutrient Distribution Range (AMDR) for protein is 10%.
7. The upper threshold for Acceptable Macronutrient Distribution Range (AMDR) for protein is 30% for 4 to 18 year olds; 35% for 19 year olds and over.
8. Within individual variance was estimated at the national level and applied at the provincial level.
9. The dietary age-sex reference intake groups have been preferred to other classifications to respect established standards from the American Institute of Medicine.
10. When comparing estimates, it is important to use confidence intervals to determine if differences between values are statistically significant. Confidence intervals describe sampling variability and give an indication of the precision of a given estimate.
11. Bootstrapping techniques were used to produce the coefficient of variation (CV) and 95% confidence intervals (CIs).
12. Data with a coefficient of variation (CV) from 16.6% to 33.3% are identified as follows: (E) use with caution.
13. Data with a coefficient of variation (CV) greater than 33.3% were suppressed due to extreme sampling variability and are identified as follows: (F) too unreliable to be published.
