Early childhood executive control modulates negative affectivity's role in increasing adolescent body mass index trajectories
Authors' conclusion
For children without robust executive control abilities early in development, negative affectivity may be a risk factor for accelerated adolescent BMI growth. Targeted assessment of early risk factors may be useful for childhood obesity prevention efforts.
Study context
- Population
- Children assessed at age 5.25 (executive control tasks; temperament by parent-completed Child Behavior Questionnaire), BMI calculated annually at ages 14–17
- Participants
- 229 children
- Outcome
- Adolescent BMI trajectories
- Follow-up
- Ages 14-17
Main finding
As reported in the abstract
Adolescent BMI growth
- Greater early negative affectivity predicted more positive BMI growth
- Early childhood executive control was not associated with BMI growth
- Greater negative affectivity predicted greater BMI escalation at average and below average executive control abilities
Observational data: associations, not effects.
