c = total change in FV intake over time; c' = change in FV intake over time when adjusted for changes in the mediator; a = change in mediator over time; b = association between mediator and FV intake when adjusted for changes over time; ab = mediated effect using the product of coefficient test. SE, standard error. All analyses are adjusted for clustering effects and time, gender, parental education and treatment condition. ‡ p < 0.10; * p < 0.05; **p < 0.01; ***p < 0.001
