SSB = Sugar-sweetened beverages, Group = intervention and control, WS = weight status, PE = parental educational level

Analyses: Overall for all and by gender, one-way ANCOVA. Group × WS/group × PE: separate interaction analyses for weight status and for parental education, two-way ANCOVA

^†Adjusted for pre-test behaviour
