背景准确评估膳食摄入量对于研究人员和公共卫生从业人员在公共卫生方面取得进展至关重要。这在美国原住民中尤为重要，因为他们的疾病患病率明显高于美国普通人群。饮食记录，食物频率问卷（FFQ），和贝类评估调查中的美洲原住民成年人从社区推进部落民族的研究跨越生命周期（海岸）CoASTAL队列由从太平洋西北部落国家的三个部落登记处随机选择的个体组成。这项横断面研究使用了来自CoASTAL基线的数据，仅限于完成贝类评估调查（n=500）、FFQ（n=518）、饮食记录（n=444）、体重测量（n =493）和身高测量（n=496）的非妊娠成年人（18岁或以上）。配对t检验、皮尔逊相关系数和一致性百分比被用于评估饮食记录和FFQ，包括和不包括报告能量摄入（rEI）的可解释性。灵敏度和特异性以及斯皮尔曼相关系数被用来评估贝类评估调查和FFQ相比，饮食records.Results的FFQ和饮食记录的选择营养素之间的统计学显着相关性是不一样的性别。考虑到饮食记录和FFQ的rEI的可解释性，改善了男性和女性的蛋白质能量百分比、碳水化合物能量和钙的相关性强度。此外，当样本仅限于合理的rEI时，rEI（饮食记录和FFQ）与体重之间的关联变得显著。贝类评估调查发现，同样评估贝类消费相比，FFQ.Conclusions这些结果支持的好处，多项措施的饮食，包括区域和文化的具体调查，特别是美洲原住民。考虑到rEI的可接受性，可以确保更准确地估计膳食摄入量。美国饮食协会杂志2010;110：65-73。
Background Accurate assessment of dietary intake is essential for researchers and public health practitioners to make advancements in public health. This is especially important in Native Americans who display disease prevalence rates that are dramatically higher than the general US population.Objective To evaluate three dietary assessment tools: dietary records, a food frequency questionnaire (FFQ), and a shellfish assessment survey among Native American adults from the Communities Advancing the Studies of Tribal Nations Across the Lifespan (CoASTAL) cohort.Design The CoASTAL cohort was composed of randomly selected individuals from three tribal registries of Pacific Northwest Tribal Nations. This cross-sectional study used data from the baseline of CoASTAL and was restricted to the non-pregnant adults (aged 18 years or older) who completed the shellfish assessment survey (n=500), an FFQ (n=518), dietary records (n=444), weight measures (n=493), and height measures (n=496). Paired t tests, Pearson correlation coefficients, and percent agreement were used to evaluate the dietary records and the FFQ with and without accounting for plausibility of reported energy intake (rEI). Sensitivity and specificity as well as Spearman correlation coefficients were used to evaluate the shellfish assessment survey and the FFQ compared to dietary records.Results Statistically significant correlations between the FFQ and dietary records for selected nutrients were not the same by sex. Accounting for plausibility of rEI for the dietary records and the FFQ improved the strength of the correlations for percent energy from protein, energy from carbohydrate, and calcium for both men and women. In addition, the association between rEI (dietary records and FFQ) and weight became significant when the sample was limited to plausible rEI. The shellfish assessment survey was found to similarly assess shellfish consumption in comparison to the FFQ.Conclusions These results support the benefit of multiple measures of diet, including regional and culturally specific surveys, especially among Native Americans. Accounting for plausibility of rEI may ensure more accurate estimations of dietary intakes. J Am Diet Assoc. 2010;110:65-73.
