Nutrient intakes of Canadian children and adolescents at school by meal occasion and location of food preparation.

Canadian children consume a significant proportion of daily foods at school, do not benefit from any federal school food program, and have historically inadequate diets. Assessment of dietary intakes at school can inform policy discussions for the design, funding, and delivery of school-based nutrition interventions. The objectives were to examine the most recent nationally representative dietary intake data of Canadian children at school by (i) location of food preparation, (ii) meal occasion, and (iii) as a proportion of total daily intakes. Intake data from the first day 24 h dietary recalls of the 2015 Canadian Community Health Survey-Nutrition were examined for children 4-18 years old ( = 1690). Intakes were reported by location of food preparation and meal occasion and were expressed as means and as a proportion of daily intake. At school, 98.6% of children consumed foods that did not require preparation, while 37.1% consumed foods prepared at home. Lunch and snacks were the meal occasions consumed most often at school, by 85.5% and 66.1% of children. Children consumed 32.6% of their daily energy intake and between 28.4% and 35.6% of daily nutrient intakes at school. School-based nutrition interventions for frequently consumed meal occasions, such as snack or lunch programs, that include foods lower in added sugar and sodium and higher in calcium, fibre, and iron may improve the health of Canadian children.
