National Diet and Nutrition Survey Years 1-9, 2008/09-2016/17

<p>The study currently includes data and documentation covering Years 1-9 of the NDNS RP. <br> </p><p>For the 15th edition (November 2019), the following changes were made:</p><p>1) Five additional variables (astrata1 - 5) were added to the Years 1-4 individual data file, and variables cluster1 - 5 were renamed astrata1 - 5 in the Years 5-6, 7-8 and 9 individual files.<br>2) Three additional variables for year 6 (holoTC, holoTCRes, holoTC_Comment) were added to the Years 5-6 individual file, and values of the variable qwimd were updated for 210 year 5 Welsh cases.<br>3) Values of the variable qsimd were updated for 72 year 7 Scottish cases in the Years 7-8 individual file.<br>4) The documents 6533_ndns_yrs1-4_data.pdf, 6533_ndns_yrs5-6_data.pdf, 6533_ndns_yrs5-6_dataset_strata.pdf, 6533_ndns_yrs7-8_data.pdf and 6533_ndns_yr9_data.pdf were edited to reflect the data updates.</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 statusof the general population aged 1.5 years and over living in private householdsin the UK. (For details of the previous NDNS series, which began in 1992, see the documentation for studies 3481, 4036, 4243 and 5140.)<br><br>The NDNS RP is funded by Public Health England (PHE), an executiveagency of the Department of Health, and the UK Food Standards Agency (FSA) andis carried out by a consortium comprising NatCen Social Research (NatCen) and MRC Elsie Widdowson Laboratory (MRC EWL), formerly known as MRC Human NutritionResearch (HNR). Fieldwork in Northern Ireland is carried out by the NorthernIreland Statistics and Research Agency (NISRA).<br>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 <a href="https://www.gov.uk/government/publications/the-eatwell-guide">Eatwell Guide</a>. The NDNS RP provides an important source of evidence underpinning the <a href="https://www.gov.uk/government/groups/scientific-advisory-committee-on-nutrition">Scientific Advisory Committee on Nutrition</a>'s (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.<br><br>Further information is available from the gov.uk <a href="https://www.gov.uk/government/collections/national-diet-and-nutrition-survey">National Diet and Nutrition Survey</a> webpage.<br><br></p>
