BMI body mass index, CI confidence intervals, OR odds ratio
aAdjusted for baseline values, sex, SEIFA, ARIA+; and season
bWatching TV/DVDs/videos or playing electronic/video games
cBased on frequency of consumption of unhealthy foods (i.e., potato chips, lollies, chocolate, takeaway foods and sugar-sweetened soft drinks); higher scores represent a less healthy food index
