Methods	Study design: Between‐participants randomised controlled trial
Participants	Setting: Laboratory setting Setting type: Naturalistic laboratory (dining room set up in a school gymnasium) Geographical region: USA Number of enrolled participants: 31 Number (%) of enrolled participants completing the study and included in analysis: 27 (87.1%) Study completers – mean age (SD): 6.3 (2.3) Study completers ‐ sex: 42% female Specific social or cultural characteristics: Preschool and school‐age children at a local childcare centre Socioeconomic status context: Low deprivation Inclusion criteria: Children agreeing to take part in the snack time activity, agreeing to answer questions from the researchers, and agreeing to be weighed and measured Exclusion criteria: None reported
Interventions	Intervention type: Proximity Type of proximity intervention: Proximity from positioned participant (table at which seated) (distance from set point) Manipulated product type: Food Characteristics of manipulated products: Animal crackers (cookies) (in context of also manipulating carrot slices on subsequent testing session) Duration of exposure to intervention: ≤ 1 day Study arms: Seated at Table 1 (nearest to snack bowl); Seated at Table 2; Seated at Table 3; Seated at Table 4; Seated at Table 5 (farthest from snack bowl) Number of comparisons analysed: 1 Comparisons analysed: Comparison 1: Participants seated at Tables 1 and 2 (i.e. serving bowl of animal crackers placed nearest (28 cm) to table (participant seated at Table 1) plus serving bowl of animal crackers placed approximately 250 cm to table (participant seated at Table 2)); participants seated at Tables 3, 4, and 5 (i.e. serving bowl of animal crackers placed approximately 500 cm to table (participant seated at Table 3) plus serving bowl of animal crackers placed approximately 750 cm to table (participant seated at Table 4) plus serving bowl of animal crackers placed approximately 1000 cm to table (participant seated at Table 5)) Concurrent intervention components in factorial design: No Concurrent intervention components confounded with comparison of interest: N/A
Outcomes	Outcomes reported in study: Mean number of animal crackers consumed; mean number of carrot slices consumed Selection outcome analysed: N/A Measurement of selection outcome: N/A Timing of selection outcome measurement: N/A Consumption outcome analysed: Mean number of animal crackers consumed Measurement of consumption outcome: Objective Timing of consumption outcome measurement: Immediate (≤ 1 day) Secondary outcome: N/A
Funding source	Funding and conflicts of interest were not reported.
Notes	Attempted to contact authors April 2017 and November 2017 to confirm outcome data and if participants re‐randomised on each of the 2 testing days, but no response received. Cannot assume re‐randomisation, so treated as single study.
