项目摘要

Studies of diet and disease relationships are difficult to carry out and often generate conflicting results. Problems occur because measuring diet in large populations is challenging. Measurement error happens in dietary studies for lots of reasons including lack of expertise, limited food choices on assessment tools, inaccurate portion sizes, incomplete food databases and cost. Health practitioners also need suitable tools for assessment of diet in patients for diagnostic purposes and monitoring treatments.The main aim of this proposal is to improve the design, conduct, analysis and interpretation of diet studies reporting food & nutrient intakes to reduce measurement error and bias. In addition, the partnership will empower researchers and clinicians through provision of valid tools to measure food and nutrient intakes. This will be of value for a range of stakeholder groups, with the potential to make important public health impacts.Currently, unless researchers or practitioners are experts in the area of nutrition it is extremely difficult for them to include measurement of dietary behaviour in their studies. We aim to provide a resource to meet the challenges of measuring diet accurately and efficiently that incorporates new developments in technology. This will be achieved by creating a unique website containing valid, evidence based dietary assessment tools along with guidance on use linked to an analysis system generating results of foods and nutrients consumed. This resource will provide access to the best assessment tools for use in a standardised way; increasing the quality of research which is undertaken in this area.Tools for inclusion on the website will be chosen by a group of experts to provide trustworthy selection of the best dietary assessment tools. These could be questionnaires; use an interview format; or on-line completion. We expect initially 10-20 tools to be included on the website. Existing paper based questionnaires included will be converted to an on-line format with downloadable pdfs. We will establish new standards for collecting, analysing and reporting studies of diet and health. The web-site hosting the validated dietary assessment tools (DAT-eLibrary) will be interactive and provide guidance for choice of the most appropriate tool for use; printable questionnaires and forms; on-line data entry and analysis functions. At the same time, we will expand and improve existing food composition tables for the UK. The growing diversity of the UK diet with around 70,000 food items in stores has not been matched by an expansion of the standard food composition tables, with only ~7,000 items. We plan to link existing national public & food industry branded food tables to expand the choice of foods available. We will use back of pack nutrient information from food producers, fast food retailers & supermarkets to expand the food tables. National public and food industry branded food tables will be linked to support analysis of tools in the DAT-eLibrary. International food tables can also be incorporated.The final element of the project will be to create an on-line interface between the dietary assessment tools and the food composition tables. The food tables will be linked to the tools in the DAT-eLibrary. The interface will allow users to access the tools and undertake analysis. Access will either be free or minimal cost to support sustainability of the resource keeping the database up-to-date.This partnership will be a unique resource for nutrition researchers, scientists and health practitioners of value to both experts and non-experts. No other website combines in one place the resources proposed here, making this proposal the most comprehensive place to find support for research in nutrition & dietary assessment. Having a central on-line resource will be a cost effective approach to improving the quality of research in the diet and health area.

饮食和疾病关系的研究很难进行，而且经常产生相互矛盾的结果。问题的出现是因为在大规模人群中测量饮食具有挑战性。在膳食研究中，由于缺乏专业知识、评估工具上的食物选择有限、食物份量不准确、食物数据库不完整和成本等原因，测量误差会发生。卫生从业人员还需要适当的工具来评估患者的饮食，以用于诊断目的和监测治疗。该提案的主要目的是改进报告食物和营养素摄入量的饮食研究的设计、实施、分析和解释，以减少测量误差和偏差。此外，该伙伴关系将通过提供有效的工具来测量食物和营养摄入量，从而增强研究人员和临床医生的能力。这对一系列利益相关者群体来说都具有价值，并有可能产生重要的公共卫生影响。目前，除非研究人员或从业者是营养领域的专家，否则他们很难将饮食行为的测量纳入他们的研究中。我们的目标是提供一个资源，以满足准确和有效地测量饮食的挑战，结合技术的新发展。这将通过创建一个独特的网站来实现，该网站包含有效的、以证据为基础的饮食评估工具，沿着使用指南，该指南与生成食物和营养素消耗结果的分析系统相关联。该资源将提供以标准化方式使用的最佳评估工具;提高在该领域进行的研究质量。网站上包含的工具将由一组专家选择，以提供最佳饮食评估工具的可靠选择。这些可以是问卷调查;使用访谈格式;或在线完成。我们预计最初将在网站上包含10-20个工具。现有的纸质问卷将转换为可下载的pdf在线格式。我们将建立收集、分析和报告饮食与健康研究的新标准。经验证的膳食评估工具网站（DAT-eLibrary）将是互动式的，并为选择最合适的使用工具提供指导;可打印的问卷和表格;在线数据输入和分析功能。与此同时，我们将扩大和改进英国现有的食物成分表。英国饮食的日益多样化，商店里大约有70，000种食物，但标准食物成分表的扩展却没有匹配，只有大约7，000种食物。我们计划将现有的国家公共和食品行业品牌食品表连接起来，以扩大可用食品的选择。我们将使用来自食品生产商、快餐零售商和超市的包装背面营养信息来扩大食品表。国家公共和食品行业品牌食品表将被链接，以支持DAT-eLibrary中的工具分析。该项目的最后一项内容是在饮食评估工具和食物成分表之间建立一个联机接口。食物表将与DAT-eLibrary中的工具链接。该界面将允许用户访问这些工具并进行分析。访问将是免费的或最低的成本，以支持资源的可持续性，保持数据库的最新。这种伙伴关系将是营养研究人员，科学家和卫生从业人员的专家和非专家的价值的独特资源。没有其他网站在一个地方结合了这里提出的资源，使这个建议成为最全面的地方，为营养和饮食评估研究提供支持。有一个中央在线资源将是一个成本效益的方法，以提高在饮食和健康领域的研究质量。
