Digital Family-Based Treatment for Childhood Obesity

(FBT 2 Trial)

This trial tests a new digital program called FBT 2.0 (Family-Based Treatment), designed to help children with obesity and their caregivers manage weight more effectively. The goal is to determine if this online program can better support families with engaging and personalized tools compared to standard educational materials alone. Families will participate in the program for six months, completing modules and receiving guidance from trained interventionists. Children diagnosed with obesity (BMI at or above the 95th percentile) and who have a caregiver willing to participate are good candidates for this study. As an unphased trial, this study offers families the opportunity to access innovative support tools that could enhance their weight management journey.

The trial information does not specify whether participants must stop taking their current medications.

Research has shown that family-based treatment (FBT), the foundation of FBT 2.0, is generally safe and effective for children with obesity. Although specific data on side effects for FBT 2.0 is not yet available, traditional FBT has enabled families to manage weight without major issues.

Researchers are excited about the Digital Family-Based Treatment (FBT 2.0) for childhood obesity because it leverages technology to engage families in a comprehensive approach. Unlike traditional options that often involve in-person sessions or basic educational materials, FBT 2.0 offers a fully digital platform that allows families to access interactive modules from home. Each family receives personalized support through weekly interventionist-led sessions and additional coaching via text or video, making it more flexible and accessible. This digital format not only empowers families to work on healthy habits at their own pace but also ensures consistent guidance and support throughout the six-month program.

Studies have shown that Family-Based Treatment (FBT) helps children and teens with obesity achieve significant weight changes. Research indicates that FBT involves the whole family in the treatment process to assist children with overweight or obesity. In this trial, participants will receive either FBT 2.0, a digital version of this treatment, or an information-and-referral control intervention. FBT 2.0 is designed as an easy-to-use, interactive program for families to manage weight effectively. Previous findings suggest that this approach is not only cost-effective but also supports better weight management compared to usual care. The digital format of FBT 2.0 provides personalized, engaging, and supportive help that families can conveniently access from home.¹²⁴⁶⁷
