Research that aims to discover whether what we eat affects our health has been hampered by lack of accurate tools to collect information on diet. Such a measurement tool would need to collect and analyse data in a reasonable time frame, with enough detail, flexible enough for different ages and ethnic groups and at minimal cost. At the moment there is no such dietary assessment tool available in the UK. This study will make use of the internet to develop a new UK focussed dietary assessment tool based on the Automated Multiple Pass Method (AMPM) developed in the USA. The AMPM uses 5 cycles of questioning to obtain a detailed account of food eaten in the past 24 hours. A search engine allows participants to select from several thousand food items in an extensive food database. This project has three main components. 1) Development of a new UK on-line dietary assessment tool. Existing online tools from the US and France (ASA24, DietDay, Nutrinet Sante) will be compared using focus groups. 30 potential users will be divided into 3 groups according to age: adolescent; adult; elderly (post-retirement). Following this the new UK tool will be developed based on the American ASA24 tool as template. 2) The second part of the study is a validation study, to see how the new tool compares to existing ?gold standard? approaches. We will compare food and nutrient intakes assessed by the on-line tool with foods and nutrients obtained using an interviewer administered dietary recall (the AMPM) both in comparison to independent biomarkers of nutrients: specifically urinary N (for protein); potassium; sucrose and fructose; and total energy expenditure. 200 participants will provide repeated measurements over 6 months. We will look at differences in agreement between the biomarkers and nutrient intakes as assessed by the average of measurements from both the on-line recall and the AMPM. 3) The final part will be a pilot study to see how well the new tool will work in practise with two different epidemiological cohorts. A subgroup of 200 older women in the UK Women?s Cohort plus their adult children and adolescent grandchildren and 100 participants from the Clinical Biobank at Imperial, a clinic based cohort with mixed population characteristics, will complete 3 on-line recalls over 6 months.Dissemination of the tool is key and open access vital. We intend to provide the software free of charge to other UK researchers.

旨在发现我们吃的东西是否会影响我们的健康的研究由于缺乏收集饮食信息的准确工具而受到阻碍。这种衡量工具需要在合理的时间范围内收集和分析数据，数据要足够详细，对不同年龄和族裔群体要足够灵活，而且费用要最低。目前，英国还没有这样的饮食评估工具。这项研究将利用互联网开发一个新的英国重点饮食评估工具的基础上，自动多遍法（AMPM）在美国开发的。AMPM使用5个询问周期来获得过去24小时内所吃食物的详细说明。一个搜索引擎允许参与者从一个广泛的食物数据库中选择数千种食物。该项目有三个主要组成部分。1)开发新的英国在线膳食评估工具。将使用焦点小组对美国和法国的现有在线工具（ASA 24、DietDay、Nutrinet Sante）进行比较。30名潜在用户将根据年龄分为3组：青少年;成年人;老年人（退休后）。在此之后，将以美国ASA 24工具为模板开发新的英国工具。2)研究的第二部分是验证研究，看看新工具与现有工具相比如何？黄金标准？接近。我们将通过在线工具评估的食物和营养素摄入量与使用访谈者管理的饮食回忆（AMPM）获得的食物和营养素进行比较，两者都与营养素的独立生物标志物进行比较：特别是尿N（蛋白质）;钾;蔗糖和果糖;和总能量消耗。200名参与者将在6个月内提供重复测量。我们将通过在线回忆和AMPM的平均测量值来评估生物标志物和营养素摄入量之间的一致性差异。3)最后一部分将是一项试点研究，以了解新工具在两个不同的流行病学队列中的实际工作情况。一个由200名英国老年妇女组成的小组妇女？的队列加上他们的成年子女和青少年孙子女以及来自帝国临床生物库的100名参与者，一个具有混合人群特征的基于诊所的队列，将在6个月内完成3次在线召回。我们打算向其他英国研究人员免费提供该软件。
