Background and study aims
Previous studies have shown that students have low fruit and vegetable intakes, and that there are very few interventions targeting fruit and vegetable consumption in students. The aim of this study is to test an intervention in the campus environment aiming to increase students’ fruit and vegetable intakes.
Who can participate?
First and second year students at HAS University of Applied Science
What does the study involve?
Fruits and snack vegetables are provided in the afternoon in a mobile cart in the form of a miniature wooden house which is placed in the central hall of the university building. By means of questionnaires students self-reported intakes of fruit, snack vegetables, total vegetables, cooked vegetables, and side dish vegetables are assessed before and after the intervention.
What are the possible benefits and risks of participating?
Benefits of the intervention are a possible higher fruit and vegetable consumption and the health benefits of this higher consumption. The risk of the intervention are food allergies, but students can choose if they take the fruits and vegetables out of the cart. Participating in the questionnaire has a minimal burden.
Where is the study run from?
HAS University of Applied Science (Netherlands)
When is the study starting and how long is it expected to run for?
February 2017 to May 2018
Who is funding the study?
Topsector Horticulture and Starting materials, with co-funding of the Triodos Foundation and Royal FloraHolland
Who is the main contact?
Ms Nicole van den Bogerd

| Health condition(s) or problem(s) studied | Fruit and vegetable intake |
| Intervention | Fruits and snack vegetables were provided in the afternoon in a mobile cart in the form of a miniature wooden house which was placed in the central hall of the university building. This intervention has been tested three times, each time for three weeks, with a pretest-post-test design without a control group. By means of questionnaires students self-reported intakes of fruit, snack vegetables, total vegetables, cooked vegetables, and side dish vegetables were assessed. |
| Intervention type | Behavioural |
| Primary outcome measure | Self-reported fruit and snack vegetable intake, assessed using a Food Frequency Questionnaire at the pretest and post-test, and the follow-up in experiment 2 (6 weeks after the intervention) |
| Secondary outcome measures | 1. Self-reported total vegetable intake, cooked vegetable intake, side dish vegetable intake, assessed with questionnaires at the pretest and post-test, and the follow-up in experiment 2 2. Perceived taste of the fruits and vegetables that were offered and effectiveness of the intervention evaluated with new developed questionnaires during the post-test of experiment 2 |

| IPD sharing plan summary | Available on request |
| Publication and dissemination plan | All three experiments will be described in one manuscript. Data will be analysed separately and pooled. |
| IPD sharing plan | The datasets generated during and/or analysed during the current study are/will be available upon request from Nicole van den Bogerd. Questionnaire and observational data (amount of fruits and vegetables provided and used) is available at any reasonable request from researchers affiliated with a university or research institute with an ORCID. All participants in the questionnaires provided informed consent at the pretest, and data is only available without identifying information of the participants. Reasonable requests include additional data analysis of, for example, fruits and vegetable intakes, adherence to fruit and vegetable guidelines or meta-analysis. Data will available as soon as the researchers involved in the project approve the request. Data is available in a .sav or .xlsx format, and only in Dutch. |
