Efficacy of a Home-Based Parent Training-Focused Weight Management Intervention for Preschool Children: The DRIVE Randomized Controlled Pilot Trial

Objectives: To pilot-test a home-based parent training intervention aimed at maintaining body weight among children at risk for obesity (> the 75th body mass index percentile). Methods: Sixteen parent–child dyads were randomized to a health education or Developing Relationships that Include Values of Eating and Exercise (DRIVE) intervention arm. The DRIVE curriculum was a structured parenting program to promote healthy weight in children by relying on behavioral principles to promote skill acquisition in the family's natural setting. Body weight and waist circumference were measured at baseline and weeks 9 and 19. Results: Body mass index z-score, body weight, and percent body weight increased in children in the health education arm vs DRIVE at weeks 9 and 19. Body weight, percent body weight, and waist circumference decreased in parents in DRIVE vs the health education arm at week 19, whereas no differences were shown at week 9. Conclusions and Implications: The DRIVE program mitigated weight gain in a small sample of at-risk children and showed promising results in reducing weight in parents. Home-based interventions emphasizing parent–child interactions are indicated as a practical model to deliver weight management in children.
