Neighborhood‐Level Variation in the Effectiveness of Intensive Health Behavior and Lifestyle Treatment for Pediatric Obesity
Authors' conclusion
Bright Bodies participation was associated with BMI reduction among all COI/COI-HE subgroups, but the highest COI/COI-HE groups had the greatest reductions.
Study context
- Population
- First-time participants (2008–2018) in Bright Bodies, a family-based intensive health behavior and lifestyle treatment for pediatric obesity, with initial BMI ≥ 85th percentile; mean age 11.7 years, 60.1% female; 80.8% in Low Child Opportunity Index (COI), 66.5% in Low COI-Healthy Environment (COI-HE) neighborhoodsyouth
- Participants
- 391 participants
- Exposure
- Monthly BMI change by neighborhood COI and COI-HE
- Outcome
- Monthly change in BMI percent of the 95th percentile (%BMIp95)
Methodological detailsmultivariable mixed effect linear regression
- Multivariable mixed effect linear regression
Main finding
As reported in the abstract
Monthly %BMIp95 change
High COI
−1.86
mean · 95% CI −2.40–-1.33
Moderate COI
−1.17
mean · CI −1.59–-0.75
High COI-HE
−2.32
mean · CI −2.78–-1.85
Low COI-HE
−1.53
mean · CI −1.75–-1.32
COI subgroups: P = 0.039 for interaction · COI-HE subgroups: P = 0.004
Observational data: associations, not effects.
