Effect of Learning on Vegetable Acceptance by Toddlers (WP23_HabEat)

Learning Mechanisms of Food Preferences in 2-3 y. o. Toddlers in Nurseries

The aim of this study is to understand the formation of food preferences from an early age.

Study Overview

• Status: Completed
• Conditions: Food Preference

Detailed Description

The main purpose of this research is to compare the effectiveness of two mechanisms (mere exposure, flavour-flavour learning) in the short and medium term (up to six months after the learning phase) on 2-3 year-old children's vegetable acceptance. the research is conducted on children aged 2 to 3 years in daycares.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Vegetable intake and liking	Measure of salsify and carrot puree intake and liking by toddlers at lunch, at pre-exposure before the exposure phase	baseline = Pre-exposure at one week before the beginning of the experimental manipulation (i.e. exposure phase)

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
Vegetable intake and liking	Measure of salsify puree intake and liking by toddlers at lunch, during the exposure phase	exposure period: 4 weeks, twice a week
Vegetable intake and liking	Measure of salsify and carrot puree intake and liking by toddlers at lunch, one week after the exposure phase	Measure at post-exposure one week after the end of the experimental manipulation (i.e. exposure phase)
Vegetable intake and liking	Measure of salsify intake and liking by toddlers at lunch, at follow-up one month after the exposure phase	1-month follow-up, conducted one month after the end of the experimental manipulation (i.e. exposure phase)
Vegetable intake and liking	Measure of salsify and carrot puree intake and liking by toddlers at lunch, at follow-up three months after the exposure phase	3-month follow-up conducted three months after the end of the experimental manipulation (i.e. exposure phase)
Vegetable intake and liking	Measure of salsify and carrot puree intake and liking by toddlers at lunch, at follow-up six months after the exposure phase	6-month follow-up conducted six months after the end of the experimental manipulation (i.e. exposure phase)
