What this trial studies
This clinical trial aims to evaluate the feasibility and preliminary effectiveness of a mobile health intervention designed to improve diet quality among adolescents aged 14-17 years who are overweight or obese. Participants will engage in a two-arm randomized controlled trial, completing dietary recalls, providing urine samples, and using continuous glucose monitors and activity trackers. The study will compare the control and intervention groups to assess improvements in diet quality and meal timing traits. The overarching goal is to determine if a digital-based approach can effectively enhance dietary habits in this population.
Who should consider this trial
Good fit: Ideal candidates are adolescents aged 14-17 years with a body mass index between the 85th and 99th percentile and a Healthy Eating Index score below 80.
Not a fit: Patients with a history of eating disorders or conditions that significantly alter dietary intake may not benefit from this intervention.
Why it matters
Potential benefit: If successful, this intervention could lead to improved dietary habits and better health outcomes for adolescents struggling with overweight or obesity.
How similar studies have performed: Previous studies have shown that digital-based interventions can improve dietary intake in adolescents, suggesting potential for success in this approach.
