Insights
Family-based interventions improved child health behaviors for pediatric obesity prevention. While body mass index (BMI) did not change, family routines and health behaviors showed significant positive impacts.
Area of Science:
- Public Health
- Pediatrics
- Behavioral Science
Background:
- Pediatric obesity is a significant public health challenge.
- Family-based behavioral interventions are recommended but lack real-world testing.
- Few interventions are evaluated in diverse, low-income populations.
Purpose of the Study:
- To assess a family-based intervention's effectiveness in pediatric primary care.
- To evaluate impacts on child and family health outcomes.
- To determine if the intervention reduces excess weight gain in children.
Main Methods:
- 240 families with children (6-12 years) and BMI ≥85th percentile were randomized.
- Intervention group received Family Check-Up 4 Health (FCU4Health) for 6 months.
- Outcomes included child BMI, body fat, and caregiver-reported health behaviors.
Main Results:
- No significant differences in child BMI or body fat between groups.
- Significant improvements in child health behaviors at 12 months in the intervention group.
- Improved family health routines at 6 months mediated behavior changes.
Conclusions:
- The FCU4Health intervention positively impacted child and family health behaviors related to pediatric obesity.
- The intervention shows promise for managing factors contributing to childhood obesity.
- BMI did not significantly differ, suggesting a need for longer-term studies or combined approaches.
Background:
Paediatric obesity is a multifaceted public health problem. Family based behavioural interventions are the recommended approach for the prevention of excess weight gain in children and adolescents, yet few have been tested under "real-world" conditions.
Objectives:
To evaluate the effectiveness of a family based intervention, delivered in coordination with paediatric primary care, on child and family health outcomes.
Methods:
A sample of 240 families with racially and ethnically diverse (86% non-White) and predominantly low-income children (49% female) ages 6 to 12 years (M = 9.5 years) with body mass index (BMI) ≥85th percentile for age and gender were identified in paediatric primary care. Participants were randomized to either the Family Check-Up 4 Health (FCU4Health) program (N = 141) or usual care plus information (N = 99). FCU4Health, an assessment-driven individually tailored intervention designed to preempt excess weight gain by improving parenting skills was delivered for 6 months in clinic, at home and in the community. Child BMI and body fat were assessed using a bioelectrical impedance scale and caregiver-reported health behaviours (eg, diet, physical activity and family health routines) were obtained at baseline, 3, 6 and 12 months.
Results:
Change in child BMI and percent body fat did not differ by group assignment. Path analysis indicated significant group differences in child health behaviours at 12 months, mediated by improved family health routines at 6 months.
Conclusion:
The FCU4Health, delivered in coordination with paediatric primary care, significantly impacted child and family health behaviours that are associated with the development and maintenance of paediatric obesity. BMI did not significantly differ.
