Dietary data was collected in 11 – 12y olds in Northumberland schools to explore dietary intakes over time (4) . To explore changes in the diet quality of schoolchildren aged 11 – 12 years in Northumberland in 2010 and 2022. Ethics approval was obtained from Newcastle University Research Ethics Committee (reference 1861/695). Participants were recruited, using opt-out consent, and completed three-day diet diaries at two time points, including week and weekend days. A follow-up interview clari fi ed information and dietary data was entered into Intake24 (intake24.co.uk), an online dietary assessment tool. Diet quality scores were calculated using the diet quality index for adolescents (DQI-A), this uses food group intakes and is com-posed of three components including diet quality, diet diversity and diet equilibrium(3). Socioeconomic status was classi fi ed using pupil postcodes and the English Index of Multiple Deprivation 2019 (IMD) and separated into quintiles with quintile 1 being the least deprived (Q1) and quintile 5 the most deprived (Q5). Analyses explored mean change of DQI-A and IMD between 2010 and 2022, and mean DQI-A scores for packed and school lunch consumers in 2010 and 2022 using t-tests, analyses were conducted in Stata v17. A total of 341 children participated (2010 n = 215; 2022 n = 126). Similar numbers of males and females participated: M = 108, F = 107 (2010); M = 60 F = 62
