National Diet and Nutrition Survey : Young People Aged 4 to 18 Years, 1997

<P>Abstract copyright UK Data Service and data collection copyright owner.</P><p>The National Diet and Nutrition Survey (NDNS) Rolling Programme (RP) began in 2008 and is designed to assess the diet, nutrient intake and nutritional status of the general population aged 1.5 years and over living in private households in the UK. (For details of the previous NDNS series, which began in 1992, see the documentation for studies 3481, 4036, 4243 and 5140.)</p><p>The programme is funded by Public Health England (PHE), an executive agency of the Department of Health, and the UK Food Standards Agency (FSA).</p><p>The NDNS RP is currently carried out by a consortium comprising NatCen Social Research (NatCen) (NatCen, contract lead)&nbsp;and the MRC Epidemiology Unit, University of Cambridge (scientific lead). The MRC Epidemiology Unit joined the consortium in November 2017. Until December 2018, the consortium included the MRC Elsie Widdowson Laboratory, Cambridge (former scientific lead). In Years 1 to 5 (2008/09 – 2012/13) the consortium also included the University College London Medical School (UCL).</p><p>Survey activities at the MRC Epidemiology Unit are delivered with the support of the National Institute for Health Research (NIHR) Cambridge Biomedical Research Centre (IS-BRC-1215- 20014), comprising the NIHR BRC Nutritional Biomarker Laboratory and NIHR BRC Dietary Assessment and Physical Activity Group. The NIHR Cambridge Biomedical Research Centre is a partnership between Cambridge University Hospitals NHS Foundation Trust and the University of Cambridge, funded by the NIHR.&nbsp;</p><div>The NDNS RP provides the only source of high quality, nationally representative UK data on the types and quantities of foods consumed by individuals, from which estimates of nutrient intake for the population are derived. Results are used by Government to develop policy and monitor progress toward diet and nutrition objectives of UK Health Departments, for example work to tackle obesity and monitor progress towards a healthy, balanced diet as visually depicted in the&nbsp;<a title="Eatwell Guide" href="https://www.gov.uk/government/publications/the-eatwell-guide" style="background-color: rgb(255, 255, 255);">Eatwell Guide</a>. The NDNS RP provides an important source of evidence underpinning the&nbsp;<a title="Scientific Advisory Committee on Nutrition" href="https://www.gov.uk/government/groups/scientific-advisory-committee-on-nutrition" style="background-color: rgb(255, 255, 255);">Scientific Advisory Committee on Nutrition</a>&nbsp;(SACN) work relating to national nutrition policy. The food consumption data are also used by the FSA to assess exposure to chemicals in food, as part of the risk assessment and communication process in response to a food emergency or to inform negotiations on setting regulatory limits for contaminants.</div><div><br></div><p>Further information is available from the gov.uk&nbsp;<a title="National Diet and Nutrition Survey" href="https://www.gov.uk/government/collections/national-diet-and-nutrition-survey">National Diet and Nutrition Survey</a>&nbsp;webpage.</p><p><br></p><br>The survey of young people aged 4 to 18 years aimed to collect data on diet through a questionnaire and a 7-day weighed intake record for a nationally representative sample living in private households in Great Britain. The study also included a 7-day bowel movement record, a 7-day physical activity diary, anthropometric and blood pressure measurem ents, a spot urine sample and a blood sample. The survey consisted of two parts: Part 1, the Diet and Nutrition Survey, and Part 2, the Oral Health Survey.<br> <br> In addition to the aims of the survey series as a whole, the survey of young people was designed to:<ul><li>provide data to assist in the development of dietary guidelines for young people, including dietary guidelines for food provided by schools</li><li>determine the frequency of bowel movement in this age group</li><li>provide baseline and comparative data for blood pressure and some anthropometric measurements in this age group</li><li>provide baseline and comparative data for some haematological and biochemical indices in blood and urine in this age group</li></ul><br><B>Main Topics</B>:<BR><br>There are two groups of datasets, primary datasets containing data in the format originally collected and derived datasets.<br> <br> The primary data includes dietary data from the food diary at four levels: person level, day level (seven days were collected per diary), plate level (this is a group of foods consumed together at the same serving) and food item level. It includes data from the physical activity diary for seven days and the keyed anthropometric data. The dataset also contains a file of blood and urine analyte data. <br> <br> The derived datasets provided include average nutrient intake for each person, intake of food sub-groups, nutrient intakes at the food item level and average daily intake of each of 55 nutrients from different food types. In addition, SPSS data files are provided containing the key derived variables for the initial dietary interview, the smoking and drinking self-completion, blood and urine analytes, physical measurements and variables derived from the physical activity diary data.<br> <br> This study also contains the MAFF nutrient databank, used to convert food weights into nutrient intake. <br> <br> Full details of the datasets are provided in Section 4 of the User Guide. Specifications for the derived variables are given in Appendix J of the User Guide.本摘要版权归英国数据服务中心（UK Data Service）及数据采集版权所有者所有。 <p>全国饮食与营养调查（National Diet and Nutrition Survey, NDNS）滚动项目（Rolling Programme, RP）于2008年启动，旨在评估英国私人家庭中1.5岁及以上普通人群的饮食结构、营养素摄入及营养状况。（有关1992年启动的初代NDNS系列研究详情，请参阅编号为3481、4036、4243及5140的研究文档。）</p> <p>本项目由英国卫生部下属执行机构英国公共卫生署（Public Health England, PHE）及英国食品标准局（UK Food Standards Agency, FSA）联合资助。</p> <p>目前，NDNS滚动项目由NatCen社会研究中心（NatCen Social Research, NatCen，合同牵头方）与剑桥大学MRC流行病学单元（MRC Epidemiology Unit, University of Cambridge，科学牵头方）组成的联盟负责实施。剑桥大学MRC流行病学单元于2017年11月加入该联盟；2018年12月前，联盟成员还包括剑桥MRC埃尔西·威德森实验室（MRC Elsie Widdowson Laboratory, Cambridge，前科学牵头方）。在第1至5年度（2008/09—2012/13），联盟成员还包含伦敦大学学院医学院（University College London Medical School, UCL）。</p> <div>剑桥大学MRC流行病学单元的调研工作得到了英国国家卫生与保健研究院（National Institute for Health Research, NIHR）剑桥生物医学研究中心（编号IS-BRC-1215-20014）的支持，该中心下设NIHR BRC营养生物标志物实验室与NIHR BRC膳食评估与体力活动研究组。NIHR剑桥生物医学研究中心是剑桥大学医院国民保健信托基金会与剑桥大学的合作机构，由NIHR资助。</div> <div>NDNS滚动项目是英国唯一具备全国代表性的高质量个体食物消费种类与摄入量数据来源，可据此推算人群营养素摄入水平。英国政府利用该项目结果制定政策，并追踪英国各卫生部门饮食与营养目标的达成进度，例如用于开展肥胖防控工作，以及监测《饮食均衡指南》（Eatwell Guide）中所倡导的健康均衡饮食的推进情况。本项目同时为国家营养科学咨询委员会（Scientific Advisory Committee on Nutrition, SACN）开展全国营养政策相关工作提供关键证据支撑。食品消费数据还被英国食品标准局用于评估人群食品化学物质暴露水平，以此作为食品突发事件风险评估与沟通流程的一部分，或为制定污染物监管限值的谈判提供依据。</div> <div><br></div> <p>更多详情可访问gov.uk平台上的全国饮食与营养调查专题网页。</p> <p><br></p> <br>针对4至18岁青少年的调研旨在通过问卷与7天称重饮食记录，为大不列颠地区私人家庭中的全国代表性样本收集饮食相关数据。本研究同时包含7天排便记录、7天体力活动日志、人体测量与血压检测、即时尿液样本采集及血液样本采集。调研分为两部分：第一部分为饮食与营养调查，第二部分为口腔健康调查。 <br> 除了本系列调研的整体目标外，青少年调研还旨在达成以下目标：<ul><li>提供数据支撑青少年膳食指南的制定工作，包括学校供餐膳食指南</li><li>明确该年龄段人群的排便频率</li><li>获取该年龄段人群血压与部分人体测量指标的基线与对比数据</li><li>获取该年龄段人群血液与尿液中部分血液学及生化指标的基线与对比数据</li></ul> <br><b>核心主题</b>:<br><br>本数据集分为两类，一类为原始数据集，保留原始采集格式的数据；另一类为衍生数据集。 <br> 原始数据集包含来自食物日记的四级膳食数据：个体水平、单日水平（每份日记采集7天数据）、餐食水平（同一餐次共同食用的一组食物）及食物条目水平。此外还包含7天体力活动日志数据、录入完成的人体测量数据，以及血液与尿液分析物数据文件。 <br> 本次提供的衍生数据集包含：个体平均营养素摄入水平、食物亚组摄入量、食物条目水平的营养素摄入数据，以及来自不同食物类别的55种营养素的日均摄入量。此外还提供SPSS格式数据文件，包含初始膳食访谈、烟酒情况自填问卷、血液与尿液分析物、身体测量指标及从体力活动日志数据中衍生得到的核心变量。 <br> 本研究同时包含MAFF营养素数据库，用于将食物重量换算为营养素摄入量。 <br> 数据集的完整详情请参阅用户指南第4部分，衍生变量的规范说明请参阅用户指南附录J。
