 Baseline assessments will include child and parent demographic data, medical history, and cognitive functioning, along with anthropometric measures such as height, weight, and body composition. Those who complete baseline assessments will be enrolled in one of two groups of family-based treatment on after-school evenings 8 pairs in each group; total of 16 child-caregiver pairs. A total of 24 weekly treatment sessions lasting up to 90 minutes each will be held over 6 months. Family-based behavioral treatment is a manualized, group intervention for children with obesity and their caregivers that incorporate participant-driven goal-based changes in diet and physical activity, and a variety of interactive educational session topics and behavioral support for reaching goals. A private weigh-in for children and caregivers will be conducted at each session. Sessions will begin with check-in with each family about weekly goal progress, after which the caregivers and children will split into separate groups for session-specific content including educational material tailored to nutrition, eating, and activity. The final portion of group session will involve children and caregivers merging in one group to share learning experiences and engage in collaborative goal-setting for the upcoming weeks. After the six month family-based behavioral intervention, baseline measures will be reassessed as well as overall program adherence. Program adherence will be evaluated using weekly program attendance and the number of days dietaryphysical activity self-monitoring logs were completed.
