Evaluation of consumer transactions as a source of dietary consumption information

Lead Research Organisation: University of Leeds
Department Name: Sch of Geography

Abstract

This project will compare a method of self-reported dietary assessment, which is often subject to reporting bias, with and arguably objective measure of food purchasing records from consumer transactions on store loyalty cards.
There will be a strong methodological focus to the project using the two data sources to better understand patterns in dietary behaviours and assessing how well the two data sources agree in different subgroups of the population. There will be a primary data collection component which will involve recruiting a group of participants to complete multiple 24h dietary recalls to allow us to compare this measure of habitual diet, with one derived from their loyalty card transactions. Diet data will be collected using the new 24h online tool, myfood24.

Description Dietary purchase patterns vary by small area geography. Even within a single city, there is substantial variation in the fruit and vegetable purchasing patterns of the populations according to retailer data from a single store. A difference was observed according to Output Area Classification, with people in more deprived urban areas purchasing fewer fruit and vegetables than those in less deprived suburban and rural areas.
Exploitation Route The findings reveal spatial and sociodemographic inequalities in diet which may be used to inform policy to improve the accessibility and affordability of healthy diets within the populations most in need.

PI Contribution The research outputs provided by myself and the research team provide valuable insight to the retailers about the purchase habits of their customers from a nutritional perspective.
Collaborator Contribution The retailer provides match-funding for the PhD project as well as transaction data used in the analysis. The partner also allows controlled access to a sub-sample of their customers as research participants. In doing so, the retailer undertakes population sampling and provides insight into the data provided in the form of meta-data. The retailer also provided additional funding to enable Victoria Jenneson to attend the Federation of European Nutrition Societies (FENS) 2019 conference in Dublin, Ireland to present two posters with findings from the collaboration.
Impact The collaboration has led to a strengthening partnership between the retailer and the University of Leeds which has already resulted in additional research projects between the partners, with further potential in the pipeline. The collaboration is a multi-disciplinary partnership bringing together food retail and academia in the fields of nutrition, public health and geography. So far, this has resulted in two poster publications which were presented at FENS 2019. The retailer hopes to use the findings of the work from this partnership to improve its offering of healthy, affordable food which will in turn promote public health nutrition benefits.

Results and Impact Activities stand discussing the use of data to make the world a better place. Activities aimed at children and their parents which sparked discussion around the ethics for data access and security. In general members of the pubic were supportive of beneficial data uses but wanted transparency and consent.
