The National Diet and Nutrition Survey (NDNS) follow-up study, ‘Diet, nutrition and physical activity in 2020 – a follow-up study during COVID-19’, was published in September 2021. This webinar will describe the background, methods, findings and limitations of the study which aimed to describe and assess the impact of the COVID-19 pandemic on the diet and physical activity of people in the UK in 2020. Self-reported diet and physical activity data were collected for around 1,000 adults and children from August to October 2020 and compared with their diet and activity data obtained at the time of their original NDNS rolling programme interview, on average 2 years 7 months earlier. Data on food security, financial security and changes in dietary and health-related behaviours since the start of the COVID-19 pandemic in the UK in February 2020 were also collected in this study through a web questionnaire with the aim of helping to understand the context for any changes in diet and activity. The follow-up study used the new NDNS dietary assessment method based on the online recall tool Intake24. The webinar will also describe this major methodological change for NDNS, summarise the findings of the first stage of evaluation, also published in September, and plans for further evaluation.
