| Child frequency of consumptionc | 1.13 | 1.08–1.18 |
| Monitor | 1.22 | 1.10–1.38 |
| Larger than recommended | ||
| Adult PS in line (vs. small) | 2.38 | 1.80–3.15 |
| Adult PS above (vs. small) | 5.58 | 4.12–7.53 |
| Child Liking b | 0.95 | 0.91–0.99 |
| Child frequency of consumption c | 1.22 | 1.16–1.28 |

a Based on 659 participants and six individual HED snack food items (cereal, chocolate coated cookie, mini milk chocolate buttons, salted potato chips, swiss roll and white toast), 555 responses missing at random or removed due to a snack food item not being consumed before, b Based on a 10 point Likert scale, c Mean frequency of consumption per week based on the Food Frequency Questionnaire (FFQ) scale [56], Reference category = recommended snack portion size.
