Insights
A family-based behavioral intervention (LAUNCH) significantly reduced obesity in preschool children compared to standard care. This intensive approach improved child BMI and parent weight loss, showing lasting effects at follow-up.
Area of Science:
- Pediatrics
- Public Health
- Behavioral Science
Background:
- Childhood obesity is a significant public health concern requiring effective interventions.
- Preschool-aged children with obesity and their overweight parents are a target population for early intervention.
- Current primary care approaches may lack the intensity needed for substantial obesity reduction.
Purpose of the Study:
- To evaluate the efficacy of a clinic and home-based behavioral intervention (LAUNCH) for reducing obesity in preschool children.
- To compare the LAUNCH intervention with enhanced standard care (Pediatrician Counseling; PC).
- To assess the long-term effects of the intervention at 12-month follow-up.
Main Methods:
- A randomized controlled trial involving 18 preschool children (aged 2-5 years) with BMI ≥95th percentile and an overweight parent.
- Intervention group received the LAUNCH program, a family-based behavioral intervention focusing on nutrition and activity.
- Control group received one-time Pediatrician Counseling (PC) with diet and activity recommendations.
Main Results:
- The LAUNCH intervention resulted in significantly greater reductions in child BMI z-score, BMI percentile, and weight gain at 6 and 12 months compared to PC.
- Parents in the LAUNCH group experienced significantly greater weight loss at both 6 and 12 months.
- The positive effects of the LAUNCH intervention were maintained at the 12-month follow-up.
Conclusions:
- An intensive, family-based behavioral intervention incorporating child behavior management strategies is more effective for reducing preschool obesity than low-intensity counseling.
- The LAUNCH program demonstrates promise for sustainable obesity reduction in young children and their families.
- Findings suggest that intensive interventions may be necessary for significant and lasting impact on childhood obesity in primary care settings.
Abstract:
We evaluated the efficacy of a 6-month clinic and home-based behavioral intervention (Learning about Activity and Understanding Nutrition for Child Health; LAUNCH) to reduce obesity in preschool children ≥95th BMI percentile compared to enhanced standard of care (Pediatrician Counseling; PC). LAUNCH was a family-based behavioral intervention that taught parents to use child behavior management strategies to increase healthy eating and activity for their children and themselves. PC presented the same diet and activity recommendations, but was delivered in a one-time PC session. Eighteen children aged 2-5 years (mean 4.71 ± 1.01) with an average BMI percentile of 98 (±1.60) and an overweight parent were randomized to LAUNCH or PC. Assessments were conducted at baseline, 6 months (end of LAUNCH treatment) and 12 months (6 months following LAUNCH treatment). LAUNCH showed a significantly greater decrease on the primary outcomes of child at month 6 (post-treatment) BMI z (-0.59 ± 0.17), BMI percentile (-2.4 ± 1.0), and weight gain (-2.7 kg ± 1.2) than PC and this difference was maintained at follow-up (month 12). LAUNCH parents also had a significantly greater weight loss (-5.5 kg ± 0.9) at month 6 and 12 (-8.0 kg ± 3.5) than PC parents. Based on the data from this small sample, an intensive intervention that includes child behavior management strategies to improve healthy eating and activity appears more promising in reducing preschool obesity than a low intensity intervention that is typical of treatment that could be delivered in primary care.
