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.

此申请请求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、提供并支持最先进的方法和 与饮食数据收集和分析相关的数据库 饮食和健康的研究。 NCC拥有最全面、最详细的 适用于研究目的的食品和营养数据库。 方法论、质量控制和培训都是最高质量的 研究所需。 NCC 人员的地位、活动、 软件、数据库和支持服务均记录在清单中 支持的研究、客户调查员、来自的支持信 全国调查人员以及 450 份来自科学界的参考文献 在其研究中使用 NCC 方法和数据库的文献。 提出了三个目标。 目标 1 的活动将维护和更新 NCC 数据库包含与某种物质相关的 18,000 种食品和 108 种营养素 新的交互式、基于计算机的软件系统（NDS-R 4.0）来收集、 编码，并分析饮食数据以生成消耗的营养物质。 五 额外的营养字段将被添加到数据库中并更新 数据库的版本大约每隔 九个月以来，国家粮食供应的快速变化可能 代表。 Aim 2 的活动将增强新的 NDS-R 软件， 和内部计算机程序来维护数据库，以进一步 提高灵活性并节省数据处理时间。 两个修订版 面试系统的详细信息将被开发并发布给客户。 Aim 3 的活动将设计、生产和验证一种新的 方法和软件工具，使调查人员能够修改现有的 食物频率集中于某种营养素。 的一个例子 将开发反式脂肪酸的方法并在 健康成年人样本。 拟议的工作将使 NCC 能够继续 为了支持全国生物医学研究，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 控制研究人员提供软件、数据库和技术的成本 饮食相关的研究服务。
