OxTalks is Changing
OxTalks will soon move to the new Halo platform and will become 'Oxford Events.' There will be a need for an OxTalks freeze. This was previously planned for Friday 14th November – a new date will be shared as soon as it is available (full details will be available on the Staff Gateway).
In the meantime, the OxTalks site will remain active and events will continue to be published.
If staff have any questions about the Oxford Events launch, please contact halo@digital.ox.ac.uk
Pregnancy, Food Purchases and Nutritional Quality
Pregnancy is a critical period for health investments, bolstered by extensive public health guidance and evidence that healthy prenatal environments foster child development with lifelong benefits. We provide new evidence on the impact of conception on nutritional choices during pregnancy and infancy, using an event study and household scanner data. Households make considerable healthy adjustments in alcohol and fruit purchases. Yet, despite these, the nutritional quality of food choices, measured using the FSA’s nutrient profiling model, declines substantially during pregnancy. The magnitude of the decline amounts to 50% of the mean difference in nutritional quality between a normal weight and an obese individual. It is caused largely by increased purchases of ultra-processed, high-sugar foods currently in the focus of food regulation. The deterioration of nutritional quality varies little by socio-economic status, pregnancy risk factors and food price environments, resulting in a fairly universal in-utero exposure to less healthy food environments.
