National Diet and Nutrition Survey Years 1-11, 2008-2019

<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><p>The study currently includes data and documentation covering Years 1-11 of the NDNS RP.</p><p>The Yrs 9-11 food level dietary data are presented in separate annual files due to their size, rather than one combined file as for previous years. A syntax file is included for SPSS users to join these files together if required.</p>

<p>For the 19th edition (October 2021) serials and stratification variables have been updated for Y9-11 to correct an error whereby cluster was not independent across survey years. Y11 Supplements data have also been appended to the dataset. Minor edits have also been made to the Yr1-4 and Yr9-11 individual data files and the Yr 9-11 User Guide and Variables List documents updated.</p><br><B>Main Topics</B>:<BR><br>The study includes dietary data obtained from an unweighed four-day food diary and information from a face-to-face interview (on food shopping, preparation and eating habits, smoking and drinking, physical activity,&nbsp; general health), physical measurements (height and weight) and collection of a spot urine sample. A nurse interview is also conducted to collect information on prescribed medicines take physical and blood pressure measurements&nbsp; and a blood sample.&nbsp; Other measures may have been included in other years.

《国家饮食与营养调查》（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、营养素摄入水平及营养状况。（关于1992年启动的前序NDNS系列研究详情，请参阅研究编号3481、4036、4243及5140的相关文档。）
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）与英国食品标准局（UK Food Standards Agency, FSA）联合资助。
当前NDNS滚动项目由以下机构组成的联盟负责实施：国家社会研究中心（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）。剑桥大学MRC流行病学单元于2017年11月加入该联盟；2018年12月之前，联盟还包含剑桥MRC埃尔西·威德森实验室（MRC Elsie Widdowson Laboratory, Cambridge，前科学牵头方）。在项目第1至5年（2008/09—2012/13）期间，联盟还包括伦敦大学学院医学院（University College London Medical School, UCL）。
剑桥大学MRC流行病学单元的调查工作得到了英国国家卫生与保健研究所（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饮食评估与身体活动研究组。NIHR剑桥生物医学研究中心由剑桥大学医院国民保健信托基金会与剑桥大学合作组建，由NIHR资助。
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类型与摄入量数据来源，可据此推算人群营养素摄入水平。英国政府利用该研究结果制定政策，并监测英国卫生部门饮食与营养目标的推进进度，例如用于应对肥胖问题的相关工作，以及监测《饮食指南（Eatwell Guide）》中所可视化呈现的健康均衡饮食目标的落实情况。本项目还为国家营养科学咨询委员会（Scientific Advisory Committee on Nutrition, SACN）的国家营养政策相关工作提供了重要的证据支撑。食品消费数据同时被英国食品标准局（FSA）用于评估人群的食品化学品暴露水平，作为应对食品突发事件的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。

本研究当前包含NDNS滚动项目第1至11年的相关数据与文档。
由于数据量较大，第9至11年的食物水平膳食数据以单独的年度文件形式提供，而非此前年份的合并文件。研究附带了语法文件，供SPSS用户根据需要将这些文件合并使用。
**最新版本信息**
在2021年10月发布的第19版中，针对第9至11年的数据更新了序列变量与分层变量，以修正不同调查年份间聚类不独立的错误。此外，第11年的补充数据已追加至数据集中。研究还对第1至4年及第9至11年的个体数据文件进行了小幅修订，并更新了第9至11年的用户指南与变量列表文档。
**核心研究内容**
本研究的数据来源包括：无称重记录的四天食物日记膳食数据、面对面访谈收集的信息（涉及食品采购、制备与饮食习惯、烟酒使用情况、身体活动与整体健康状况）、身体测量数据（身高与体重）以及即时尿液样本采集。此外，研究还会开展护士访谈，收集受试者的处方药服用情况、身体测量与血压测量数据以及血液样本。部分年份的研究还纳入了其他测量指标。
