Note. Dietary factors are adjusted for total energy using the nutrient density approach with the
exception of fibre where total kilocalories were entered as an additional covariate.
1Based on the Canadian Food Guide, HEI assigns a score (max = 100) based on diet quality of the individual.
2Mixed Grain Fibre variable includes fibre in grams from mixed foods including grains.
* P-trend <0.05; ** P < 0.01; *** P < 0.001.
