在北极社区，人们注意到粮食不安全和营养转型。因此，我们评估了生物标志物的营养状况和营养素摄入量的传统食品（TF）和因纽特人在加拿大的粮食安全状况。2007-2008年对36个北极社区的因纽特人（>= 18岁）进行了一项横断面健康调查。使用美国农业部问卷和营养摄入量通过24小时饮食召回来评估粮食安全。生物标志物包括血清25-羟基维生素D [25（OH）D]、血红蛋白、血清铁蛋白和红细胞RBC脂肪酸（FA）。分析按过去一天TF消费（是与否）和食品安全状态（安全与不安全）分层。食物不安全是普遍的（62.6%），与较高的RBC trans-FA和较低的血红蛋白水平和血清铁蛋白相关，而TF摄入与较高的血清25（OH）D，（n-3）FA和血清铁蛋白相关（P
Food insecurity and the nutrition transition have been noted in arctic communities. We therefore evaluated biomarkers of nutritional status and nutrient intakes by traditional food (TF) and food security status among Inuit in Canada. A cross-sectional health survey of Inuit (>= 18 y) in 36 arctic communities was conducted in 2007-2008. Food security was assessed by 24-h dietary recalls using USDA questionnaires and nutrient intakes. Biomarkers included serum 25-hydroxy vitamin D [25(OH)D), hemoglobin, serum ferritin, and erythrocyte RBC fatty acids (FA). Analyses were stratified by past-day TF consumption (yes vs. no) and food security status (secure vs. insecure). Food insecurity was prevalent (62.6%) and associated with higher RBC trans-FA and lower hemoglobin levels and serum ferritin, whereas TF consumption was associated with higher serum 25(OH)D, (n-3) FA, and serum ferritin (P
