目标.计算阿拉斯加2个地区的能量和营养素摄入量，并描述阿拉斯加原住民（AN）慢性疾病发展的影响。研究设计。横断面观察，10个村庄和2个枢纽社区生病阿拉斯加农村; 333名参与者，年龄13至88岁。经过培训的访谈者收集了4个季节的24小时饮食回忆。在这两个地区，AN报告了传统的本地食物和商店购买的食物的组合;大部分能量来自商店购买的食物，高比例的营养素来自本地食物，特别是蛋白质，铁和欧米茄-3脂肪酸。从鱼类和海洋哺乳动物中摄入的欧米茄-3脂肪酸的平均摄入量是美国普通人群的20倍以上。蛋白质、铁、硒、维生素A、维生素C（男性）和叶酸（男性）的平均摄入量符合推荐水平，钙和纤维的摄入量低于推荐水平;碳水化合物和饱和脂肪（%能量）高于推荐水平。传统食物继续为阿拉斯加农村的饮食提供大量的营养。过量的单糖可能会导致肥胖和糖尿病的增加。钙、膳食纤维、水果和蔬菜的低摄入量可能导致消化系统癌症的发病率增加。强调本土食物的积极方面，增加水果、蔬菜和富含钙的食物的消费是必要的。(Int J Circumpolar Health 2009;68（2）：109-122）
Objectives. To calculate the energy and nutrient intake in 2 regions of Alaska and to describe the implications for development of chronic disease among Alaska Native people (AN).Study design. Cross-sectional observation, 10 villages and 2 hub communities ill rural Alaska; 333 participants ages 13 to 88 years old.Methods. Trained interviewers collected 24-hour diet recalls during 4 seasons.Results. In both regions, AN reported a combination of traditional Native foods and store bought foods; most of the energy comes From store-bought foods a high proportion of nutrients come from Native foods, especially protein, iron and omega-3 fatly acids. Mean intakes of omega-3 fatty acids, from fish and sea mammals, are over twenty times greater than those of the general U.S. population. Mean intakes of protein, iron, selenium, vitamin A, vitamin C (men) and folate (men) met recommended levels, intakes of calcium and fiber were below recommended levels; carbohydrate and saturated fat (% energy) were above.Conclusions. Traditional foods continue to contribute it significant amount of nutrients to the diet in rural Alaska. Excess simple sugars may be contributing to the rise in obesity and diabetes. Low intakes of calcium, dietary fiber, fruits, and vegetables may contribute to the increased incidence of cancers of the digestive system. Emphasis oil the positive aspects of Native foods and increased consumption of fruits, vegetables and calcium-rich foods are warranted. (Int J Circumpolar Health 2009;68(2):109-122)
