Abstract

Dietary habits among Arctic preschoolers are unknown. A cross-sectional health survey of 388 Inuit, aged 3–5 y, was conducted in 16 communities in Canada’s Nunavut Territory. Twenty-four–hour recall and FFQ with parents and primary caregivers quantified diet from market and traditional foods (TF). The Institute of Medicine’s Dietary Reference Intakes estimated adequacy comparing intakes with Estimated Average Requirement or Adequate Intakes (AI). High-sugar and high-fat food and sugar beverage consumption and the extent to which dietary habits followed the Canadian Food Guide were evaluated. The children’s mean age was 4.4 ± 0.9 y and the mean BMI percentile was 90.2%. Consumption of nutrient-poor and energy-dense food and beverages contributed to 35% of energy. Most children met the requirements for many nutrients despite not eating the recommended servings from Eating Well with Canada’s Food Guide First Nations, Inuit and Métis. Higher intake of TF resulted in higher intakes of cholesterol, vitamins A and D, iron, magnesium, and zinc. The percent above the AI for vitamin D was 43.1, 56.8, and 83.2% among no, low, and high TF consumers, respectively (χ2 test; P-trend < 0.0001). Dietary habits indicate a population at risk for overweight, obesity, and tooth decay. Interventions should encourage TF, including plant-based TF; healthy market food choices, including fruit and vegetables; and milk or alternative sources of vitamin D and calcium and discourage unhealthy market food choices.
