Trend in FV intake and the mediated effect of preferences and accessibility on this trend

	c (SE)	c' (SE)	a(SE)	b (SE)	ab (SE)
FV intake	-0.55 (0.29)‡
Accessibility		1.42 (0.26)***	1.08 (0.15)***	0.82 (0.04)***	0.89 (0.13)***
Preferences		0.83 (0.26)**	0.31 (0.15)*	0.83 (0.04)***	0.25 (0.12)*

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
