  1. Note: Unweighted percentages. Percentages are rounded so may not sum to 100%
  2. *Significant difference across phase (p < 0.05)
  3. a Adults’ self-reported height and weight was used to calculate their BMI: weight (kg) / [height (m)] [2] which was classified into weight categories according to internationally recognised cut-offs [75]. BMI could not be calculated for n = 30 at baseline, n = 95 at Toxic Fat 2012/13, n = 24 at Sugary Drinks 2013/14, n = 32 at Toxic Fat/Sugary Drinks 2014, n = 16 at Junk Food 2016, n = 19 at Junk Food 2017, n = 22 at Sugary Drinks 2018, and n = 25 at Junk Food 2019 due to missing data
  4. b Socioeconomic area was determined according to the Index of Relative Socio-Economic Disadvantage (IRSD) rankings for Western Australia as described by the Australian Bureau of Statistics (2016) [56] based on respondents’ home postcodes. Low IRSD indicates greater disadvantage, high IRSD indicates least disadvantage. No IRSD value was available (or unknown/invalid postcode reported) for n = 5 at baseline 2012, n = 20 at Toxic Fat 2012/13, n = 4 at Sugary Drinks 2013/14, n = 5 at Toxic Fat/Sugary Drinks 2014, n = 5 at Junk Food 2016, n = 7 at Junk Food 2017, n = 5 at Sugary Drinks 2018, and n = 7 at Junk Food 2019
  5. c Respondents were classified as parents if they indicated they were the parent or main carer of one or more children aged under 18 who live with them
  6. d WA population proportions for these age groups were calculated as proportions of this age range (25–49 years) in the general population
  7. e Source: WA Health and Wellbeing Surveillance System (2016)
  8. f Tertiary education is defined as formal post-secondary education, including qualifications ranging from undergraduate awards (bachelor’s degrees, associate degrees and advanced diplomas) to postgraduate awards (graduate certificates and diplomas, master’s and doctoral degrees)
