Subjects are dependent observations between T1 and T4 with valid measurements at T2
Bold - significant p-value < 0.05
b = regression coefficient, estimates of intervention group
OR = odds ratios for the intervention group
¹Serving sizes (examples below):
Snacks = 1.5 dl of crisps or cheese doodles
Sweets = about 1.5 dl of sweets or 4 pieces from a chocolate bar
Cakes = a small bun or 5 small biscuits
Ice-cream = a small ice cream bar or 1 dl ice-cream
Drinks = 1.5 dl
Vegetables = 2 dl grated carrots/cabbage or a large tomato or 2–3 broccoli heads

²Aggregated variables: unhealthy foods (snacks, sweets/chocolate, ice-cream, cakes/buns/cookies), healthy foods (fruit and vegetables) and unhealthy drinks (soft drink, flavoured milk, and fruit juice > 1 serving)
³Stratified analysis due to interaction effect (group × sex)
