SES = socioeconomic status; B = unstandardized coefficient, OR = Odds ratio, 95% CI = 95% Confidence Interval. Bold values represent statistically significant association.
Model A: Single mediator model. This model includes the mediator `parental fruit consumption'.
Model B: Single mediator model. This model includes the mediator `parental rules regarding fruit consumption'.
Model C: Single mediator model. This model includes the mediator `home availability of fruit'.
Model D: Multiple mediation model. This model includes the mediators: parental fruit consumption, parental rules regarding fruit consumption and home availability of fruit.
Model E: Single mediator model. This model includes the mediator `parental vegetable intake'.
Model F: Single mediator model. This model includes the mediator `parental rules regarding vegetable consumption'.
Model G: Single mediator model. This model includes the mediator `home availability of vegetables'.
Model H: Multiple mediator model. This model includes the mediators: parental vegetable consumption, parental rules regarding vegetable consumption and home availability of vegetables.
Model I: Single mediator model. This model includes the mediator `parental breakfast consumption'.
All models are adjusted for: child's age, child's gender, child's ethnicity and child's BMI.
