Traditional foods are rich sources of essential nutrients, but Inuvialuit in the Northwest Territories (NWT), Canada, have been undergoing a nutrition transition, characterised by an increased consumption of non-nutrient-dense foods. The present study aimed to characterise energy, nutrient and food intakes amongst adult Inuvialuit.
The study collected up to three 24-h dietary recalls on nonconsecutive days for each participant in spring/summer of 2008 in one remote community in the NWT. Recall data were analysed for energy and nutrient intake, dietary adequacy, most commonly reported foods, and food contributors to energy and nutrients.
Participants included 14 men and 50 women (response rate 79%). Median daily energy intake was 9.4 (interquartile range=5.7) MJ for men and 8.3 (3.6) MJ for women. The majority of adult Inuvialuit did not meet the recommendation for vitamins A [median intake=344.7 (246.3) μg-RAE in men, 248.9 (213.8) μg-RAE in women], B(6) [0.9 (0.8) mg in men, 1.0 (0.5) mg in women] and E [2.4 (2.1) mg in men, 1.8 (1.0) mg in women], dietary fibre [7.7 (5.7) g in men, 8.7 (4.4) g in women], calcium [779.6 (842.0) mg in men, 610.4 (431.5) mg in women] and total folate [222.6 (57.7) μg in men, 264.6 (127.5) μg in women]. Vitamin D intake was below the recommendation for most women [median intake=100.0 (119.2) IU]. Traditional foods contributed substantially to protein and iron intake. Juices were the main contributors to energy, carbohydrate and calcium.
The present study revealed an inadequate consumption of essential nutrients in an Inuvialuit population. If these nutrient deficiencies continue, this population will face an increased burden of chronic diseases and malnutrition.
传统食物是必需营养素的丰富来源，但加拿大西北地区的因纽特人经历了营养转型，其特点是食用非营养密集型食物的比例增加。本研究旨在描述成年因纽特人的能量、营养素和食物摄入量。
本研究于 2008 年春夏在西北地区的一个偏远社区收集了每位参与者最多三次连续 24 小时的饮食回忆。对回忆数据进行了能量和营养素摄入、膳食充足性、最常报告的食物以及能量和营养素的食物来源分析。
参与者包括 14 名男性和 50 名女性（应答率为 79%）。男性的日均能量摄入量中位数为 9.4（四分位间距=5.7）MJ，女性为 8.3（3.6）MJ。大多数成年因纽特人未达到维生素 A[男性中位数摄入量=344.7（246.3）μg-RAE，女性 248.9（213.8）μg-RAE]、维生素 B(6)[男性 0.9（0.8）mg，女性 1.0（0.5）mg]和维生素 E[男性 2.4（2.1）mg，女性 1.8（1.0）mg]、膳食纤维[男性 7.7（5.7）g，女性 8.7（4.4）g]、钙[男性 779.6（842.0）mg，女性 610.4（431.5）mg]和总叶酸[男性 222.6（57.7）μg，女性 264.6（127.5）μg]的推荐摄入量。大多数女性维生素 D 摄入量低于推荐值[中位数摄入量=100.0（119.2）IU]。传统食物对蛋白质和铁的摄入有很大贡献。果汁是能量、碳水化合物和钙的主要来源。
本研究揭示了因纽特人群必需营养素摄入不足。如果这些营养素缺乏持续存在，该人群将面临更多的慢性病和营养不良负担。
