What this trial studies
This study investigates the effectiveness of a mobile health intervention based on the Health Belief Model and family involvement to enhance oral health behaviors among adolescents aged 12 to 15. It is a 30-month cluster randomized controlled trial involving three groups, where parents and their children will receive targeted mobile messages aimed at improving oral hygiene practices and reducing sugar intake. The primary outcome is the increment of dental caries two years post-intervention, while secondary outcomes include changes in oral health self-efficacy and behaviors, as well as dental plaque and gingival bleeding indices.
Who should consider this trial
Good fit: Ideal candidates are Chinese adolescents aged 12 to 15 living with their parents or primary caregivers who have access to mobile phones.
Not a fit: Patients on special diets or with medical conditions affecting growth or eating may not benefit from this study.
Why it matters
Potential benefit: If successful, this intervention could significantly improve oral health behaviors in adolescents, leading to a reduction in dental diseases.
How similar studies have performed: Previous studies have shown promise in using mobile health interventions for health behavior changes, suggesting potential success for this approach.
