Who uses your data?


The Government uses results from the survey to make decisions that improve public health and protect food safety. Results from the survey have led to public health campaigns such as Change4Life which encourages people to “Eat well, move more and live longer”.


Once results from the survey have been published by the Government, academics study these results for their own research purposes. Academics have looked at a number of interesting diet and nutrition issues, including how parental employment shapes children’s eating habits.

Who has access to my data?

The data controllers for this study are Public Health England (PHE) and the Food Standards Agency (FSA). NatCen Social Research is the data processor for this study. Northern Ireland Statistics and Research Agency (NISRA) is also a data processor for fieldwork in Northern Ireland. Please note that the lawful basis for processing data as identified by the data controllers is “performance of a task carried out in the public interest or in the exercise of official authority vested in the controller” (Article 6(1) (e)). An additional condition has been identified by the data controllers for processing special category data (including biometric data). This states that “processing is necessary for archiving in the public interest, scientific or historical research purposes or statistical purposes based on UK law” (Article 9(2) (j)). Our research collaborator, the University of Cambridge MRC Epidemiology Unit, has access to biological samples you may provide. They have access to some personal, but non-identifiable, data for research and analysis purposes. For logistical reasons, we work with the following third parties: DPD, Formara and Stor-A-File. We also employ a Freelance Research Associate who assists with data management.

What will happen to any information I give?

We will handle your data in accordance with the EU General Data Protection Regulation (GDPR). The personal information we collect about you is used in order to undertake our survey. This includes arranging appointments to collect information from you and feeding back results from your blood tests. The results and any urine and/or blood samples collected will be used for research and statistical purposes only, for the purpose of improving public health.

In the future, NatCen may want to contact you about follow-up research on health. We will only invite you to take part in follow-up research if you give written consent for this. If you are invited to take part in any future studies you will be free to refuse if you do not want to take part.

Do I have to take part?

Providing personal details and taking part in the study is not a statutory or contractual requirement, and participation is therefore completely voluntary. There will be no consequences for you as a participant if you choose not to provide personal data, and you have the right to withdraw from the study at any point.

Where is my data stored?

All personal data will be stored securely, in line with NatCen’s certification to ISO27001 and Cyber Essentials Plus. No personal identifiable data, such as your name or contact details, will be transferred to another country.
