To explore the relationship among children's diet quality, weight status and food environment in subarctic Canada.
In the cross-sectional study, children's BMI was calculated, diet quality was assessed using three 24 h dietary recalls and children were asked about their home food environment and source of meals.
Two Aboriginal Cree communities in northern Québec.
Two hundred and one children in grades 4-6.
The majority (64.2%) of children were overweight (29.9%) or obese (34.3%). Weight status was not associated with reported restaurant meal frequency or the home food environment. The 18% of children who consumed three or more restaurant meals in the three days of recall consumed, on average, 2004 kJ (479 kcal) more energy daily than children consuming no restaurant meals and had higher intakes of fat, saturated fat, Ca and soda. Most foods contributing to energy and dietary fat were energy-dense market foods of low nutritional value such as sweetened beverages and snack foods. Only 68% of children reported often having fruits and vegetables in the home and 98.5% of children consumed less than 5 fruits and vegetables daily. Many children (42.8%) were at risk of Zn inadequacy. Only 19% of children consumed 2 or more servings of milk daily, and the mean intakes of Ca and vitamin D were below the recommended adequate intake. Traditional game meat was consumed infrequently, but contributed significantly to Fe and Zn intake.
Childhood obesity in subarctic communities prevailed in a food environment typified by high-energy-density commercial foods of low nutritional value.
探讨加拿大亚北极地区儿童饮食质量、体重状况与食物环境之间的关系。
在这项横断面研究中，计算儿童的体重指数（BMI），通过三次24小时饮食回顾评估饮食质量，并询问儿童有关家庭食物环境和膳食来源的情况。
魁北克省北部的两个克里族原住民社区。
201名四至六年级的儿童。
大多数（64.2%）儿童超重（29.9%）或肥胖（34.3%）。体重状况与报告的外出就餐频率或家庭食物环境无关。在回顾的三天中，有18%的儿童食用了三次或更多次外出就餐，他们每天平均比未外出就餐的儿童多摄入2004千焦（479千卡）能量，并且脂肪、饱和脂肪、钙和汽水的摄入量更高。大多数提供能量和膳食脂肪的食物是能量密集型的低营养价值市场食品，如含糖饮料和休闲食品。只有68%的儿童报告家中经常有水果和蔬菜，98.5%的儿童每天食用的水果和蔬菜少于5份。许多儿童（42.8%）有锌摄入不足的风险。只有19%的儿童每天饮用2份或更多份牛奶，钙和维生素D的平均摄入量低于推荐的适宜摄入量。传统野味肉食用频率较低，但对铁和锌的摄入量有显著贡献。
在以低营养价值的高能量密度商业食品为特征的食物环境中，亚北极社区儿童肥胖问题普遍存在。
