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.

此应用程序请求对营养协调中心的支持 (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和 与收集和分析年内饮食数据有关的数据库 饮食与健康的研究。NCC拥有最全面和最详细的 适合研究目的的食物和营养数据库。 方法论、质量控制和培训是最高质量的 是研究所必需的。NCC人员的地位，活动， 软件、数据库和支持服务以清单形式记录 支持的研究，客户调查人员，来自 全国范围内的研究人员，以及来自科学研究中心的450篇参考文献 在他们的研究中使用NCC方法和数据库的文献。 提出了三个目标。目标1的活动将保持和更新 NCC数据库包含18,000种食物和108种与 新的交互式计算机软件系统(NDS-R 4.0)，以收集、 编码，并分析饮食数据以生成营养素消耗量。五 其他营养素字段将添加到数据库中，并进行更新 数据库的版本将大约每隔一年向客户发布 九个月来，国家粮食供应的快速变化 有代表性的。AIM 2的活动将增强新的NDS-R软件， 以及维护数据库的内部计算机程序，以进一步 提高灵活性并节省数据处理时间。两个修订版 将开发并向客户发布面试系统的。 Aim 3的活动将设计、生产和验证一个新的 使调查人员能够修改现有的方法和软件工具 食物频率集中在某一种营养上。这是一个示例 将开发反式脂肪酸的方法学，并在 健康成年人的样本。拟议的工作将使NCC能够继续 为了支持全国的生物医学研究，它将提供连续性 以及正在进行的和未来的研究的可比性，这将有助于 控制调查人员提供软件、数据库和 与饮食相关的研究服务。
