The Families and Schools for Health Project: A Longitudinal Cluster Randomized Controlled Trial Targeting Children...

Area of Science:

• Pediatric obesity research
• Behavioral interventions
• Public health

Background:

• Childhood obesity is a significant public health concern.
• Existing interventions often focus on single components like diet or exercise.
• The role of psychosocial factors in family and peer environments needs further investigation.

Purpose of the Study:

• To evaluate the effectiveness of combined family and peer-based psychosocial interventions on childhood obesity.
• To determine if interventions targeting family dynamics and peer group interactions enhance a lifestyle approach.

Main Methods:

• Cluster randomized controlled trial involving 538 first-grade children with BMI percentile >75.
• Four intervention conditions compared: Family Lifestyle (FL), FL + Peer Group (PG), FL + Family Dynamics (FD), and FL + FD + PG, against a control group.
• Longitudinal anthropometric data collected from 1st to 4th grade analyzed using a two-level random intercept growth model.

Main Results:

• The comprehensive FL + FD + PG intervention demonstrated a significant reduction in BMI and BMI-M% gains over three years compared to controls.
• Specific effect sizes: B = -0.05 for raw BMI and B = -2.36 for BMI-M%.

Conclusions:

• Simultaneous interventions addressing parent, child, and peer group behaviors related to physical and socioemotional health are effective.
• This multi-component approach shows promise for achieving long-term positive impacts on childhood obesity.
• Integrating psychosocial components enhances lifestyle interventions for managing pediatric obesity.
