Plain English Summary
Background and study aims
A child’s first years of life are crucial for cognitive (mental) development and future health. Studies show that a varied diet with a high intake of vegetables is positive for weight development, mental health and cognitive development. A low intake of vegetables is considered one of the greatest challenges in children’s diets in Norway. Researchers suggest that one barrier for vegetable intake among children is food neophobia. Food neophobia is defined as a reluctance to taste and eat new foods. Food neophobia increases from the age of 2 years and decreases later in childhood. Interventions that can increase children’s intake of vegetables should be introduced early in life to overcome children’s neophobia. The aim of this study is to develop and measure the effect of two different interventions for one-year-old children in kindergartens to reduce food neophobia and promote healthy diets.
Who can participate?
Children born in 2016 attending kindergartens in the counties of Oppland and Telemark in Norway
What does the study involve?
The participating kindergartens are randomly allocated to one of three groups: two different intervention groups and one control group. The first intervention group are served a warm lunch meal with a variety of vegetables on three days a week during the 3-month study period. The second intervention group are served the same meals and also give lessons and advice on meal and feeding practices. Questionnaires, information videos and recipes are included on a study web page. The control group continue their usual meal practices. To measure the effect of the interventions, parents and kindergarten staff complete questionnaires at the start of the study and after the intervention. Food neophobia, diet, food variety, vegetable liking, cognitive development, parent and kindergarten staff feeding practices, and child weight and height are all recorded. There are follow-up-questionnaires when the children are 36 and 48 months old.
What are the possible benefits and risks of participating?
The results of this study will provide new knowledge about whether or not education and a healthy meal intervention targeting children, kindergarten staff and parents will reduce levels of food neophobia in toddlers, improve parental and kindergarten feeding practices, improve children’s dietary variety, improve children’s cognitive development and reduce childhood obesity. Kindergartens in the intervention groups will increase their knowledge and competence when it comes to food and meal serving. There are no risks of participating in this study.

Study information
Scientific title
A cluster randomized web-based intervention trial among one-year-old-children in kindergarten to reduce food neophobia and promote healthy diets
Acronym
Study hypothesis
A web-based intervention that gives specific pedagogical tools and instructions to serve warm meals with a variety of vegetables aimed at one-year-old children, kindergarten personnel and parents will:
1. Reduce the children's level of food neophobia
2. Increase the children's vegetable intake
3. Improve the children's cognitive development
4. Prevent future obesity
There are two different intervention groups, and the trialists hypothesize that the group with both pedagogical tools and instructions to serve warm meals will be more effective regarding the hypotheses than the intervention group with only instructions are to serve warm meals with different vegetables.

Condition
Dietary habits, food neophobia, cognitive development, child obesity and parental and kindergarten personnel feeding practices
Intervention
The kindergartens will be randomly, consecutively allocated to either one of the intervention groups or control group based on a computer-generated list:
1. Intervention group 1 will be asked to serve a warm lunch meal with a variety of vegetables three days a week during the intervention period which will last for 3 months
2. Intervention group 2 will be asked to use given pedagogical tools including sensory lessons (the Sapere method) and advice on meal practice and feeding styles, in addition to serving the same meals as intervention group 1
3. The third group will be the control group and continue their usual practices
All the information given to the intervention groups, i.e. information videos, recipes and other necessary information, will be found in a study web page.
To evaluate effect of the interventions on the given outcomes, parents and kindergarten personnel will fill in questionnaires at baseline and post intervention. Questionnaires will be distributed by e-mail. There will be follow-up-questionnaires when the children are 36 and 48 months old.
