This application requests support for the Nutrition Coordinating Center (NCC) at the University of Minnesota, as a national research resource. NCC develops, provides, and supports state-of-the-art methods and databases related to the collection and analysis of dietary data in studies of diet and health. NCC has the most comprehensive and detailed food and nutrient database appropriate for research purposes. Methodologies, quality control, and training are of the highest quality required for research. The stature of NCC personnel, activities, software, databases, and support services is documented with listings of studies supported, client investigators, letters of support from investigators nationally, and 450 references from the scientific literature that have used NCC methods and databases in their research. Three aims are proposed. Activities for Aim 1 will maintain and update the NCC database of 18,000 foods and 108 nutrients associated with a new interactive, computer-based software system (NDS-R 4.0) to collect, code, and analyze dietary data to generate nutrients consumed. Five additional nutrient fields will be added to the database, and updated versions of the database will be released to clients approximately every nine months so rapid changes in the nation's food supply can be represented. Activities for Aim 2 will enhance the new NDS-R software, and in-house computer programs to maintain the database, to further improve flexibility and save data processing time. Two revised versions of the interview system will be developed and released to clients. Activities for Aim 3 will design, produce, and validate a new methodology and software tool to enable investigators to modify existing food-frequency focused on a certain nutrient. An example of the methodology will be developed for trans fatty acids and validated on a sample of healthy adults. The proposed work will allow NCC to continue to support biomedical research nationally, it will provide continuity and comparability for ongoing and future studies, and it will help control costs to investigators for providing software, databases, and diet-related research services.

此申请要求支持营养协调中心 （NCC）在明尼苏达大学，作为国家研究资源。 NCC开发，提供和支持最先进的方法，并且 与饮食数据的收集和分析有关的数据库 饮食和健康研究。 NCC拥有最全面，最详细的 食品和营养数据库适合研究目的。 方法论，质量控制和培训是最高质量的 研究所需的。 NCC人员，活动， 列表记录了软件，数据库和支持服务 支持的研究，客户调查人员，来自 在全国范围内调查人员和科学的450个参考文献 在其研究中使用NCC方法和数据库的文献。 提出了三个目标。 AIM 1的活动将维护和更新 NCC数据库的18,000种食物和108种营养素与 新的基于计算机的软件系统（NDS-R 4.0）收集， 编码并分析饮食数据以产生消耗的营养。 五 其他营养领域将添加到数据库中，并更新 数据库的版本大约将向客户发布 九个月如此迅速的粮食供应变化可能是 代表。 AIM 2的活动将增强新的NDS-R软件， 和内部计算机程序以维护数据库，以进一步 提高灵活性并节省数据处理时间。 两个修订版 访谈系统的范围将被开发并发布给客户。 AIM 3的活动将设计，生产和验证一个新的 方法和软件工具使研究人员能够修改现有 食物频率集中在某种营养素上。 一个例子 将开发用于反式脂肪酸的方法，并在A上进行验证 健康成年人样本。 拟议的工作将使NCC继续 为了在全国范围内支持生物医学研究，它将提供连续性 以及正在进行和未来研究的可比性，这将有助于 为调查人员控制成本，以提供软件，数据库和 与饮食有关的研究服务。
