What this trial studies

The trial tests a digital adaptation of the FIT Families family-based behavioral program delivered through a smartphone app called the Digital Wellness Nurse (DWN). Adolescents (12–17) with obesity and their primary caregivers use the app for education, self-monitoring, wearable data collection, and social support while community health workers monitor progress and meet weekly by video. The platform automates reminders and incentive prompts tied to adherence and allows additional family members to send encouragement. The primary focus is feasibility in rural African American families, measuring uptake, adherence, and acceptability of the digital delivery.

Who should consider this trial

Good fit: Ideal participants are English‑proficient African American adolescents aged 12–17 with BMI at or above the 90th percentile who live primarily with an overweight or obese caregiver in a rural community and both have smartphones with internet.

Not a fit: Those whose obesity is secondary to medications or chronic/genetic conditions, pregnant individuals, people with serious mental or emotional conditions, non‑English speakers, or families without individual smartphones or mobile internet are unlikely to qualify or to benefit.

Why it matters

Potential benefit: If successful, the DWN could expand access to evidence-based family obesity treatment in rural communities and improve teens’ self-monitoring, physical activity, and weight outcomes.

How similar studies have performed: Behavioral family programs like FIT Families have shown benefit in prior trials, but fully automated mobile nurse platforms are newer and have limited direct evidence to date.
