Effects of an obesity intervention program on cognitive function in children: A randomized controlled trial

Area of Science:

• Pediatric Health
• Cognitive Neuroscience
• Obesity Research

Background:

• Childhood adiposity is linked to diminished cognitive function.
• Understanding the impact of interventions on cognitive development is crucial.

Purpose of the Study:

• To investigate the effects of a structured obesity intervention on children's cognitive abilities.
• To assess changes in visuospatial construction, emotional control, and monitoring skills.

Main Methods:

• 115 children were randomized into a Day Camp Intervention Arm (DCIA) or Standard Intervention Arm (SIA).
• The DCIA involved a 6-week day camp (physical exercise, health classes) followed by a 46-week family-based program.
• Cognitive function and anthropometrics were assessed at baseline, 6 weeks, and 52 weeks.

Main Results:

• Significant improvements in visuospatial construction skills were observed in the DCIA group at 6 weeks (P=0.02).
• At 52 weeks, the DCIA group showed greater improvements in emotional control (P=0.002) and monitoring (P=0.04).
• No significant group differences were found for other cognitive outcomes.

Conclusions:

• The comprehensive obesity intervention positively impacted specific cognitive domains in children.
• Findings suggest that interventions targeting adiposity can enhance emotional regulation and executive functions like monitoring and visuospatial skills.
