Is it Helpful to Use Fitbits in a Family Based Weight Loss Program?

Not Applicable

• Conditions: Pediatric Obesity
• Interventions: Device: Fitbit

• Registration Number: NCT03215641
• Lead Sponsor: Children's Hospital Los Angeles

Brief Summary

This study evaluates the role of personal activity trackers to help improve weight loss or weight maintenance for children and their parents enrolled in a comprehensive weight loss program.

Detailed Description

Childhood obesity rates have tripled in the last 30 years, with as many as 50% of children in the US being obese or overweight. High-intensity comprehensive behavioral family lifestyle intervention (CBFLI) programs have been shown to be among the most effective interventions for weight loss in children. However, these programs are time- and resource-intensive with high rates of recidivism. Personal activity trackers (PAT) provide objectively measured physical activity data and are more reliable than self-report. These devices can also have a motivational impact. The investigators intend to study the effects of these devices and their data on behavior change and weight loss for both parents and children enrolled in a CBFLI program. The investigators will objectively measure the level of activity of both members of the parent-child dyad, explore the relationship between parent-child activity levels and its effect on each other, as well as on overall weight loss or weight maintenance.

Arm && Interventions

Group	Intervention	Description
Intervention	Fitbit	The intervention group families will be given fitbits on the first day of the Body Works program. They will otherwise receive the same curriculum as the control families. the will fill out the same physical activity surveys as the control families. they will receive weekly feedback based on the objectively measured physical activity.

Primary Outcome Measures

Name	Time	Method
BMI-z score	Baseline to program completion (~8 weeks)	change in BMI-z score

Secondary Outcome Measures

Name	Time	Method
impact of fitbit on program completion rate	Baseline to program completion (~8 weeks)	The investigators will evaluate if families that receive fitbits complete the program at a higher rate (completion is defined as having attended at least 4 out of 7 sessions).
Impact of fitbit on program attendance	Baseline to program completion (~8 weeks)	The investigators will evaluate if families that receive fitbits attend more sessions (out of 7 total sessions) by recording their attendance at each session
