Delay discounting and nucleus accumbens functional connectivity are related to weight status in adolescents from the Adolescent Brain and Cognitive Development (ABCD) study
Authors' conclusion
Delay discounting and nucleus accumbens functional connectivity are independently related to weight status in a large sample of early adolescents. A better understanding of the relationship between reward and overeating behaviours may better inform obesity interventions.
Study context
- Population
- 10–12-year-olds from the Adolescent Brain and Cognitive Development (ABCD) Study1,817 with connectivity data
- Participants
- 3,819 participants
- Outcome
- Relationships between weight status (BMIz, WHtRz), monetary delay-discounting performance and nucleus accumbens functional connectivity
Methodological detailssecondary analysis of the ABCD Study, multilevel longitudinal linear modelling
- Secondary analysis of the ABCD Study
- Multilevel longitudinal linear modelling
Main finding
As reported in the abstract
- Greater discounting associated with higher BMIz and WHtRz
Observational data: associations, not effects.
Further findings
Nucleus accumbens functional connectivity and BMIz
- Nucleus accumbens connectivity to cingulo-opercular, dorsal attention, fronto-parietal, salience and ventral attention networks predictive of BMIz
- Nucleus accumbens connectivity did not mediate the delay discounting–BMIz association
- N = 1817
