Registration Number

Yale University
Brief Summary

This study will evaluate the effectiveness of the Bright Bodies intervention in improving body mass index (BMI) among 7-13 year-old children with obesity simultaneously with the impact of the implementation strategy on adoption, reach, fidelity, cost, and maintenance of the intervention in three heterogenous settings serving patients disproportionately affected by obesity.

Detailed Description

The demonstrated efficacy of Bright Bodies in a well-designed randomized controlled trial (RCT) and a real-world effectiveness study reduce equipoise and challenge the ethics of a prospective RCT of implementing Bright Bodies in other settings. As such, this study is an observational, multiphase mixed methods design to evaluate effectiveness and implementation among three purposively selected heterogeneous sites serving low-income populations with racial and ethnic, rural-urban, and geographic diversity.

Children ages 7-13 years with BMI ≥85th percentile and their parent/caregivers hereafter referred to as parent will be recruited to participate in the evaluation study from among participants in the newly-established Bright Bodies programs at each of the three implementation sites. The aim is for each site to recruit approximately 40 children and their parents (a total of 120 children and 120 parents) to participate in the Bright Bodies program over the study's enrollment period. The primary outcome is change in BMI expressed as a percentage of the 95th percentile (%BMIp95) using EHR data collected as part of routine clinical care up to 36 months before and up to 15 months after enrollment in the intervention. Secondary outcomes include: (a) change in %BMIp95 at three and six months, (b) changes in parent BMI at three and six months, (d) parent-reported changes in health behaviors (sleep, physical activity, screen time, eating behaviors), via surveys at 3, 6 and 12 months, and (e) changes in parent-proxy reported weight-related quality of life, parent stress, and parent talk about weight via surveys at baseline, 6, and 12 months after enrollment. We will also describe implementation outcomes (reach, adoption, fidelity/adaptation, and cost) through qualitative and quantitative data collection from members of our study team throughout the process of implementation.

Primary Outcome Measures
NameTimeMethod
Change in %BMIp95Up to 36 months prior to baseline through up to 15 months after enrollment

Change in %BMIp95, calculated from height and weight. A negative percentage indicates that the participant's BMI has decreased since enrollment.

Secondary Outcome Measures
NameTimeMethod
Change in parent BMIBaseline through 6 months after enrollment

Change in BMI, calculated from height and weight measured as part of the Bright Bodies program. A negative change in parent BMI indicates that the parent's BMI has decreased since enrollment.

Change in weight-related quality of lifeBaseline through 12 months after enrollment

Sizing Them Up is a validated, parent-proxy reported instrument assessing weight-related quality of life for children aged 5-13 years. Possible score ranges from 1 (never) to 4 (always). Higher score indicates a higher quality of life.

Change in weight-related health behaviors.Baseline through 12 months after enrollment

Parent-proxy responses to the Bright Bodies Healthy Lifestyles Questionnaire about vegetable and fruit intake \[scores range from 1 (none) to 4 (three or more); Higher score indicates healthier behavior\]; sugar-sweetened beverage intake \[scores range from 1 (none) to 4 (three or more); Lower score indicates healthy behavior\]; intake of sweets/desserts \[scores range from 1 (none) to 4 (seven or more); Lower score indicates healthy behavior\]; physical activity \[scores range from 1 (less than 30 minutes) to 4 (more than 2 hours); higher score indicates healthy behavior.\]; screen time \[scores range from 1 (more than 4 hours) to 4 (1 hour or less); higher score indicates healthy behavior.\]; sleep \[scores range from 1 (6 hours or less) to 3 (9 hours or more) for the amount a child sleeps each night and from 1 (no) to 2 (yes) for the question about a regular bedtime; Higher score indicates healthy behavior\].

Change in binge eating behaviors.Baseline through 12 months after enrollment

Children's Brief Binge-Eating Questionnaire will be parent-proxy reported. Possible score ranges from 1 (definitely false) to 3 (definitely true). Higher scores indicate greater concern for binge eating behavior.

Change in parent conversations about weight.Baseline through 12 months after enrollment

Parent conversation about weight is measured with three questions using a parent self-report instrument from the New Moves, a school-based intervention designed to prevent obesity and other weight-related problems. Possible scores range from 1 (never) to 5 (very often). Lower score indicates less weight talk.

Per patient cost for participation in Bright BodiesFrom enrollment through 12 months after enrollment

Calculated based on data regarding resource utilization of the Bright Bodies program and participants' use of relevant medical and non-medical resources.
