*p < 0.05; analyses are complex samples GLM, with adjustments made for school clustering, and interactions with SES; post-intervention values are adjusted for baseline equivalents where available, parent age, BMI and ethnicity, and child age and gender; a higher score indicates a higher level of attitude or behaviour for all outcomes.
