Data collection and entry
Data were collected on two occasions: (i) at baseline, pre-intervention between July and October 2020 and (ii) at follow-up, in weeks 11 and 12 of the intervention implementation period (between November and December 2020). The primary outcomes were child food provision and child dietary intake. Secondary outcomes were menu compliance and intervention acceptability by staff. Due to COVID-19 restrictions at the time, modifications were made to the collection of dietary data at the follow-up time point. Due to differences in methods at baseline and follow-up, only follow-up dietary data were analysed and compared between groups.
