Inclusion criteria

Inclusion criteria: Food Stop was part of the Child Health CheckPoint (CheckPoint), which was nested within the Birth-cohort (B-cohort) of the Longitudinal Study of Australian Children (LSAC). LSAC is the only nationally-representative children’s longitudinal study in Australia. The study involves biennial data collection waves from two cohorts (B- and K-cohorts) of population-representative children and their parents. The CheckPoint study only recruited those children (age range 11-12) and their midlife parents from LSAC’s B-cohort who agreed to be contacted by the CheckPoint team (n=3513). Of the 3513 families that were invited to participate in CheckPoint, 1874 child-parent dyads took part in CheckPoint throughout Australia.
