REF reference category
aHigher scores indicate expectation of more SSB consumption/higher score on unfavourable behaviour
bR square statistic represents the estimated level of variance explained by the regression model
Note: numbers printed in bold represent significant association between independent variable and average SSB consumption in litre per day of child in that model. Asterisks’ represent the level of significance of the association between independent variable and outcome, corrected for all other variables: *p < 0.05, **p < 0.01, ***p < 0.001
