The Dose Trial: Dose Intensity of Behavioral Interventions for Childhood Obesity
Vanderbilt University Medical Center
Summary
The research team is recruiting 900 children between the ages 5-17 with obesity from Tennessee and Louisiana. The team is assigning children and their caregivers by chance to one of five groups. In the first group, 300 children and their caregivers receive 26 hours of IBT. In the second group, 300 children and their caregivers receive 13 hours of IBT. The remaining three groups of 100 children and their caregivers receive 16, 19, or 22 hours of IBT. Children's healthcare providers, nutritionists, and social workers are providing IBT to each of the groups over six months. At the start of the study and again after one year, the research team is measuring the children's body mass index, or BMI. BMI is a measure of a person's body fat based on their height and weight. The team is also looking at the children's: * Diet * Exercise * Sleep * Media use * Quality of life
Description
The Dose study aims to evaluate the optimal number of contact hours (i.e., dose) of intensive behavioral lifestyle interventions for childhood obesity. Current recommendations by the American Academy of Pediatrics (AAP) and the United States Preventive Services Task Force (USPSTF) suggest that intensive behavioral lifestyle interventions should have at least 26 hours of contact time. This is a difficult standard to achieve, as it requires significant resources from healthcare systems and time from families. This study\'s purpose is to test whether 26 hours is needed to achieve clinically m…

Interventions
- BehavioralIntensive Behavioral Lifestyle Modification
Participants in all arms will receive visits with their child's primary care provider (4 visits, 1 hour total), on-demand web-based learning modules that focus on building skills and knowledge in health behaviors (7 hours), and community resource counseling sessions delivered by a social worker or similar healthcare professional (4 sessions, 2 hours total). The difference between arms will be in the frequency and duration of personalized nutrition counseling delivered by a registered dietitian or similar healthcare professional: 16 sessions (60 minutes per session), 12 sessions (60 minutes per session), 9 sessions (60 minutes per session), 8 sessions (45 minutes per session), or 6 sessions (30 minutes per session).
