目标.本研究的目的是开发它的饮食工具（食物频率问卷[FFQ]），测量总的饮食摄入量超过一年的阿拉斯加原住民在2个地区。为了准确评估阿拉斯加原住民的饮食与他们的健康之间的关系，需要评估饮食的方法。收集季节性24小时（24-h）饮食回忆，以制定描述平均膳食食物和营养素消耗的所有FFQ。阿拉斯加原住民生活在12个小社区在2个地区的国家有资格参加。每个参与者提供4个24小时的饮食回忆，每个季节1次。使用回归技术，通过召回来制定所有FFQ。FFQ对333名原始参与者中的58名进行了管理。使用斯皮尔曼相关系数将对FFQ的反应与他们24小时回忆的平均值进行比较。能量调整的相关性范围从0.15蛋白质到0.49单不饱和脂肪酸。26种营养素中有15种（总碳水化合物、蔗糖、果糖）具有显著相关性。总脂肪，脂肪酸[单不饱和。多不饱和的omega 3、EPA、DHA]、叶酸、维生素A、C、D、钾和硒）。FFQ可用于评估阿拉斯加州西部阿拉斯加原住民相关营养素的摄入量。(Int J Circumpolar Health 2009：68（2）：99-108）
Objectives. The purpose of this Study was to develop it dietary instrument (food frequency questionnaire [FFQ]) that measured total dietary intake over I year among Alaska Native people in 2 regions. Ways of assessing diet are needed in order to accurately evaluate how the diets of Alaska Natives relate to their health.Study design. Seasonal 24-hour (24-h) diet recalls were collected for developing all FFQ that described the average dietary foods and nutrients consumed. Alaska Native people living in 12 small communities in 2 regions of the state were eligible to participate.Methods. Each participant was to provide 4 24-h diet recalls, 1 per season. Recalls were used to develop all FFQ using regression techniques. The FFQ was administered to 58 of the 333 original participants. Responses to the FFQ were compared to the averages of their 24-h recalls using the Spearman Correlation Coefficient.Results. Energy-adjusted correlations ranged from 0.15 for protein to 0.49 for monounsaturated fatty acids. Fifteen of 26 nutrients examined were significantly correlated (total carbohydrates, Sucrose, fructose. total fat, fatty acids [monounsaturated. polyunsaturated. omega 3, EPA, DHA], folate, vitamins A, C, D, potassium and selenium).Conclusions. The FFQ can be used to evaluate intakes of Alaska Natives in western Alaska for the correlated nutrients. (Int J Circumpolar Health 2009: 68(2):99-108)
