About this trial
This implementation study evaluates two strategies to increase fruit consumption among Swedish students. (1) installing fruit stands in schools and (2) combining fruit stands with a health-awareness campaign. The intervention is implemented in a set of participating schools, each following one of the predefined strategies. Students are asked to use a research app to photograph their meals and snacks during three data-collection periods before, during, and after the intervention. The study collects information on fruit intake, eating patterns, and the number of fruits taken from the stands to assess effectiveness and reduce food waste. The aim is to identify which strategy better supports healthy eating habits in school environments.

Treatments tested in this trial
Fruit Stand Availability
BehavioralFree fruit is provided to students through fruit stands placed in central school areas. Two fruit varieties are offered, and fruit uptake is monitored using digital scales integrated into the stands. Students photograph school-provided fruit before eating it and annotate it as "school fruit" in the app, while also documenting all meals and snacks as part of the study protocol.
Awareness Campaign
BehavioralA school-based awareness campaign is delivered to promote healthy eating and encourage fruit consumption. Activities may include posters, messaging, or informational content. The campaign is implemented alongside the fruit stands to enhance student engagement with the intervention.
Treatment groups
300 Participants
are divided into 2 treatment groupsGroup A: Fruit stands onlyExperimental treatment 1 intervention
Group B: Fruit stands + awareness campaignExperimental treatment 2 interventions
Trial outcomes
Primary outcomes
1
Change in fruit consumption
Measured across baseline, early-intervention, and follow-up to evaluate whether fruit consumption differs between schools receiving fruit stands alone and those receiving fruit stands plus an awareness campaign.
