Primary outcomes: food provision and child dietary intake
The primary outcomes assessed were child food provision (what children were served at mealtimes) and child dietary intake assessed against the Victorian Menu Planning Guidelines for five food groups (vegetables and legumes; fruit; cereals and breads; dairy and alternatives and meat and alternatives) and discretionary food and drinks (foods and drinks that do not fit in the five food groups as they are nutrient poor and typically higher in kilojoules, saturated fat, added sugars and/or added salt) as classified in the Australian Dietary GuidelinesChildren’s food provision and intake were measured using the standardised weighed plate wastage method for lunch and two mid-meal snacks. To adapt to COVID-19 restrictions at follow-up data collection, measurement of plate waste was modified to incorporate a hybrid use of photography and weight measures, as researchers were not permitted to enter rooms during mealtimesAll foods were entered into Excel, and an eight-digit food code was assigned to individual food items (e.g. raw carrot) using the AUSNUT 2011–2013 database
