The Dose Trial: Dose Intensity of Behavioral Interventions for Childhood Obesity
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:
