Executive function in childhood obesity: Promising intervention strategies to optimize treatment outcomes

Area of Science:

• Pediatric Obesity Research
• Neuroscience and Behavior
• Clinical Psychology

Background:

• Executive functions (EFs) are crucial for self-regulation and energy balance.
• Children with obesity frequently exhibit deficits in EFs, potentially impacting treatment efficacy.
• Understanding the interplay between EFs and obesity is vital for effective interventions.

Purpose of the Study:

• To review the role of top-down (e.g., inhibitory control, working memory) and bottom-up (e.g., attentional bias) EF processes in pediatric obesity treatment.
• To evaluate interventions aimed at improving EF and their impact on weight-loss success in children.
• To synthesize evidence on the relationship between EF, EF interventions, and weight management in youth.

Main Methods:

• Systematic review of empirical studies involving children (≤19 years) with overweight/obesity.
• Inclusion of studies with interventions targeting EF processes and measuring EF and/or relative weight.
• Analysis of pre-post intervention data to assess effects on EF and weight outcomes.

Main Results:

• Poorer executive function is associated with reduced success in pediatric weight-loss treatments.
• Preliminary evidence suggests behavioral weight-loss interventions and physical activity can positively influence EFs.
• Improvements in EFs correlate with enhanced weight loss in children.

Conclusions:

• Executive function deficits represent a significant barrier to effective pediatric obesity treatment.
• EF-focused interventions, including computer training and attention modification, show potential for improving both EF and weight outcomes.
• Further research is necessary to confirm the efficacy of these interventions and explore broader applications.
