What this trial studies

This clinical trial aims to evaluate the effectiveness of a mobile app designed to train adolescents in craving regulation to improve their dietary intake of fruits and vegetables. Participants, aged 14-18, will be randomized into either an active intervention group using the app or a control group receiving general food facts. The study will assess changes in healthy eating index scores, body mass index, waist circumference, and blood glucose levels over one year. Participants will engage with the app twice a week and undergo in-person assessments at baseline and after one year.

Who should consider this trial

Good fit: Ideal candidates for this study are biologically female adolescents aged 15 to 18 years who are interested in improving their dietary habits.

Not a fit: Patients who are biologically male or have certain medical conditions affecting growth or glucose metabolism will not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could lead to improved dietary habits and better health outcomes for adolescent girls at risk of obesity and type 2 diabetes.

How similar studies have performed: Other studies have shown promise in using mobile health interventions for dietary improvements, suggesting this approach may be effective.
