Impulsivity and reward sensitivity facets as predictors of weight change in children: Differences by binge‐eating disorder diagnostic status
Authors' conclusion
Findings indicate the importance of developing theoretical models and interventions for obesity prevention in children with BED that address emotional impulsivity.
Study context
- Population
- Nine-to-ten-year-old children recruited across the United States (Adolescent Brain and Cognitive Development study)
- Exposure
- Children with vs without binge-eating disorder (BED)
- Outcome
- BMI z-score predicted by baseline impulsivity and reward sensitivity facets
- Follow-up
- 1-year follow-up
Methodological detailssecondary analysis of the Adolescent Brain and Cognitive Development study
- Secondary analysis of the Adolescent Brain and Cognitive Development study
Main finding
As reported in the abstract
BMI-z at 1-year follow-up
- Without BED: reward sensitivity and impulsivity unrelated to BMI-z at follow-up
- BED: greater negative urgency and lower positive urgency predicted increased BMI-z at 1-year follow-up
Observational data: associations, not effects.
