来自CSFII/NHANES联合调查的摄入量数据将用于许多不同的目的，每个目的都有特定的数据要求和适当的分析方法。就监测和监督而言，膳食参考摄入量的可用性将有助于估计摄入量不足的普遍性和有不良影响风险的摄入量的普遍性。营养素摄入量估计的准确性将通过5遍膳食回忆方法、量化膳食补充剂摄入量数据的可用性以及扩大的食物和补充剂成分数据来提高。将通过使用新的数据库来计算食物指南金字塔中食物组的份量和食物商品的摄入量，改进食物层面的饮食监测。调查的另一个主要优点是能够将摄入量数据与个人健康措施联系起来。由于每个个体缺乏通常的摄入量，推断将继续受到限制，但与过去一样，2d数据的衰减将小于仅1d数据的衰减。更好的数据收集和分析也将导致更知情的营养政策和计划。应研究分析数据的创新方法，以尽量减少少报的影响，提供更好的群体和个人水平的日常摄入量估计，并准确地将食物和补充剂的营养摄入量联合收割机结合起来。未来可能会考虑对摄入量收集方法进行修改，以允许某些亚组的样本量更大，补充剂使用的更详细信息，扩展的食物频率问卷，不同的召回天数以及纳入饮食和健康知识问题。
Intake data from the combined CSFII/NHANES survey will be used for many different purposes, each with specific data requirements and appropriate analytic methods. For monitoring and surveillance, the availability of Dietary Reference Intakes will allow estimates of the prevalence of inadequate intakes and the prevalence of intakes with a risk of adverse effects. The accuracy of the nutrient intake estimates will be enhanced by the 5-pass dietary recall methodology, availability of quantified dietary supplement intake data and expanded food and supplement composition data. Food-level dietary monitoring will be improved by using new databases to calculate servings of food groups from the Food Guide Pyramid and intakes of food commodities. Another major strength of the survey is the ability to relate intake data to health measures for individuals. Inferences will continue to be limited by a lack of usual intake for each individual, but the attenuation will be less with 2 d of data than with only 1 d, as in the past. Better data collection and analysis will also lead to more informed nutrition policies and programs. Innovative methods of analyzing the data should be investigated to minimize the effects of underreporting, provide better estimates of usual intake at both the group and individual levels and accurately combine nutrient intakes from foods and supplements. Future modifications to the intake collection methods might be considered to allow larger sample sizes for certain subgroups, more detailed information on supplement use, an expanded food frequency questionnaire, a different number of recall days and incorporation of diet and health knowledge questions.
