Critique of Two Methods for Assessing the Nutrient Adequacy of Diets, A
评析了两种评估膳食营养充足性的方法：阈值法和概率法，比较了它们的假设、优缺点及适用条件，指出概率法依赖当前不可得的数据，而阈值法虽简单但易产生分类错误。
The adequacy of diets can be assessed using several analytical approaches. This paper reviews two methods of assessment: a cutoff method, which estimates the percentage of the population having usual intakes below a given value; and a probability method, which assesses the percentage of the population whose usual intakes are below their individual requirements.\nFirst, the concept pf usual nutrient intakes and the problems associated with estimating usual intake distributions are discussed. Next, the two methods of dietary assessment and their related assumptions are described and compared. The more specific inference of the probability method is shown to rely on its assumptions and data that are currently not available. While the cutoff method is simpler, its use may result in misclassification errors and its estimates are highly influenced by the cutoff standard selected.
