Promoting Vegetable Intake in Preschool Aged Children

Status Completed

Clinical Trial Summary

The aim of this cluster randomised control trial is to test the efficacy of a repeated taste exposure intervention, a nutritional educational intervention and combination of both to increase intake of an unfamiliar vegetable in preschool aged children (aged 3-5 years).

Clinical Trial Description

The aim of this study is to test the efficacy of a repeated taste exposure intervention, a nutritional educational intervention and combination of both to increase intake of an unfamiliar vegetable in preschool aged children (aged 3-5 years). In particular the study will assess whether these strategies are effective to encourage intake of an unfamiliar vegetable in children who are fussy eaters or going through the food neophobia phase. The effectiveness of these interventions will also be observed overtime at 3 and 6 months post intervention.

Nurseries will be randomised into one of four conditions over the 12 week intervention period; these include educational intervention only, taste exposures only, taste exposures and educational intervention or no intervention (control group). All children will be offered an unfamiliar vegetable prior to the intervention and after the intervention to evaluate changes in intake of the unfamiliar vegetable. The repeated taste exposure groups will be offered the novel vegetable repeatedly (1 exposure per week) over the 12 week period. For the educational intervention nursery staff will be advised to deliver two components of an existing PhunkyFoods educational programme over the same period.

Parents will be asked some general demographic questions, child food behaviour questions and questions about their feeding practices. Finally nursery staff will be requested to provide feedback to evaluate intervention feasibility, barriers and efficacy.

It is predicted that children's intake of the unfamiliar vegetable will vary by intervention. The primary hypothesis to be tested is that children who receive the repeated taste exposures are more likely to increase their intake of the unfamiliar vegetable compared to those in educational only or control conditions. The second hypothesis is that repeated taste exposures will increase intake of an unfamiliar vegetable in fussy eaters more than education. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
