Comparing fruit stands alone versus fruit stands plus an awareness campaign in schools

An Interventional Study Evaluating Two Different School Deployment Strategies, Testing the Effects of Onsite Awareness Raising on the Adoption of the Fruit-stands by Local Student Populations

Not applicable Interventional Karolinska Institutet · NCT07385820

This project will test whether putting fruit stands in schools, with or without a health-awareness campaign, helps Swedish students aged 7–19 eat more fruit.

What this trial studies

The study places fruit stands offering two types of fruit in central school areas and compares fruit availability alone to fruit availability combined with a health-awareness campaign. Participating schools are assigned to one of the two strategies and staff use digital scales on the stands to monitor fruit uptake by photographing scale readings for OCR-based weight tracking. Students use a mobile app to photograph their meals and snacks during three data-collection periods before, during, and after the intervention to capture fruit intake and eating patterns. Outcomes include number and weight of fruits taken, student-reported consumption from photos, and food waste to determine which approach better supports healthier eating in the school environment.

Who should consider this trial

Good fit: Students aged 7–19 enrolled at participating Swedish schools who can use a mobile phone to document meals and have provided informed consent (parental consent required if under 15).

Not a fit: Students not attending participating schools, those unable to use a mobile phone to document meals, or those with clinical conditions the research team deems likely to interfere may not benefit.

Why it matters

Potential benefit: If successful, the approach could increase students' fruit intake at school and support healthier long-term eating habits.

How similar studies have performed: Previous school fruit programs have often produced modest increases in fruit consumption, while evidence on added value from awareness campaigns is mixed.
